Weekend, what a shake! Hail, rain and even snow are coming. This is the most important novelty that emerges from the data that has just arrived from the main computing centers that the dose has increased compared to what they have begun to smell in recent days: among Saturday 25th and Sunday 26th February There will be a dramatic change in just 24 hours, with a Winter tail shot.
In the next few days, a special weather configuration will be established at the European level: the strengthening of the Azores anticyclone in the direction of the UK and Scandinavia will allow a downpour A huge mass of very cold airfrom offshore Arctic extraction, in the direction of Italy, which will be associated with the pre-existing low-lying vortex in the Mediterranean region.

In China, about 230,000 people have been evacuated due to Typhoon Talim. Last night I came ashore in the southern province of Guangdong. Talim continued its march towards Beibu Gulf and overnight – weakened by a tropical storm – again made landfall in Guangxi Province, which borders Vietnam.
The hurricane caused winds of up to 140 kilometers per hour. The southern province of Hainan Island was hit by waves nearly 6 meters high.
Floods and falling trees
Floods have been reported in several places. According to the Reuters news agency, people are posting videos on Chinese social media of fallen trees, floating cars, a beached whale and walkers struggling to keep their balance.
According to state media, firefighters are busy rescuing people from fallen trees and cleaning roads. The extent of the damage caused by Talim has yet to be assessed.
Residents of the city of Fuzhou, located 1,000 km east of the area where Talib made landfall, were also affected by the typhoon. From there, there were reports of cars and furniture being washed away and flood damage.
Trains and flights have been cancelled
In addition to the numerous evacuations, other precautions were taken in southern China’s provinces yesterday. Hundreds of flights and trains have been cancelled. Thousands of fishing boats have been withdrawn in Guangdong and dozens of coastal tourist destinations have been closed.
The storm is expected to weaken further as it moves northwest toward Vietnam during the day. In Quang Ninh and Hai Phong, about 30,000 people have been evacuated as a precaution.
Talim is the fourth cyclone in Asia of the year and the first to make landfall.

Snow is coming…finally!
So all this chat of El Nino we all expected to have the most amazing season of snow. Well it certainly didn’t start that way. The only snow that has fallen this season was in late November. Albeit a good snowfall it certainly wasn’t enough to kickstart the season.
Hats off to TeleVerbier who managed to keep the link to the 4 vallee’s open until yesterday and at least 2 or 3 runs on Savoleyres have been skiable and very quite. Now it’s NY week it’s certainly busier but up high the snow conditions are great.
The great news is that a storm from the atlantic is gaining some momentum and heading our way. It looks like we’re going to get a reasonable snow fall over a 7-10 day period. Cutting it a bit fine…!


Colorado digging out from big snowstorm
DENVER — Coloradans are digging out from a major snowstorm that canceled flights, delayed opening of Denver city offices and piled up snow as much as two-feet deep.
Dozens of people are waking up at Denver International Airport waiting to catch flights that were canceled after a powerful snowstorm blanketed the Front Range on Sunday. Denver officials asked city workers to come in mid-morning to allow time for snow removal.
The storm, which packed high winds and caused blizzard conditions at times, is expected to make way for sun and warmer temperatures by Monday afternoon.


(KTXL) — A pair of storm systems are heading our way.
The first storm will begin Wednesday night in Northern California. It will be enhanced by an atmospheric river, meaning there is potential for downpours.
There will be scattered on and off showers on Thursday while it snows in the Sierra.
There’s a Winter Weather Advisory in effect for elevations above 4,500 feet from 5 p.m. Wednesday to 1 p.m. Thursday. Travel will be difficult at times as 6 to 12 inches of snow accumulate.
Those patrolling Interstate 80 said they do not want a repeat of what happened earlier in the week when snow caused drivers to have trouble on the road.
“The road feels good but the conditions change minute to minute,” said Sean Nichols, who lives in Sierra.
Nichols said he has lived in the area for 15 years and that he is accustomed to driving in the storm. But he said he has noticed not everyone traveling toward the Sierra is used to the conditions.
“I had a guy trailing me at 65, and I didn’t even want to go 65. So, I just pulled over and let him by then I realized I’d rather be doing 50,” Nichols said.
Law enforcement are looking to avoid scenes like Monday.
“We had a total of 12 crashes in about a six-hour period,” said California Highway Patrol Officer Brett Martin. “One thing to remember is that what the weather is like down in the valley is oftentimes not what it is up here. It could be sunny even in Auburn and by the time you get up the hill it’s snowing.”
The next storm will likely start Friday night and be most impactful through Saturday morning.
This system looks equal or slightly stronger in strength compared to the Thursday storm. Similar snow and rain totals are expected.
While beneficial for reservoirs, these storms will not dramatically change drought conditions. They will, however, stave off what looked like an extremely early start to fire season.


Ranchi/Jamshedpur: Incessant rains disrupted normal life in Ranchi, East Singhbhum, Hazaribag, Bokaro and Giridih districts today as many rivers in the state were in spate.
The district administration of Ranchi, East Singhbhum, Hazaribagh, Bokaro and Giridih have declared school holiday tomorrow for students up to class 8 in view of incessant rains, official sources said.
Ranchi today received 70.8 mm of rainfall, the MeT sources said.
Many rivers including Damodar, Konar and Siwane were in spate owing to continuous rains since last four days.
The movement of traffic on Tati-Jharia, Hazaribag-Katakumsandi has been stalled, officials sources said, adding that many rivers were flowing over the bridges.
The local Met sources said Hazaribag has received 196.8 mm rainfall during the last 24 hours.
Meanwhile, six sluice gates of Charowa Dam reservoir was opened today as it crossed the red level. Water-logging was reported from several parts of Hazaribag, including Hurhuru, Kumhartoli, Ramnagar, where several houses inundated.
Though the situation has improved compared to yesterday, the reports of water logging was pouring from parts of the Dalbhum sub-division, said
Normal life continued to be affected in the Jamshedpur, which has registered a record rainfall yesterday after several years, even though water level in Kharkhai and Swarnarekha rivers receded a bit today.
“We are monitoring the situation round the clock as heavy rain was predicted, Sub-Divisional Officer (Dhalbhum),” Prabhat Kumar said.
A Giridih district report stated that a diversion on Giridih-Dhanbad main road was washed away in the rain.
Normal life was also affected in Seraikela-Kharswan and West Singhbhum district due to continuous rains.

Residents of Southeast Queensland have been warned to prepare for severe storms, which can cause hail, high winds and flash floods.
The Bureau of Meteorology warned that severe thunderstorms were on the weather radar in the city at 5:30 p.m. Near Boonah, Beaudesert, Laidley, Gatton and Elgin Vale in a northeasterly direction.
It was predicted that they would cover Ipswich, Coolangatta and the areas between Gympie and Murgon by 6 p.m. and Brisbane CBD, Beenleigh, and Logan City Esk until 6:30 p.m.
Previously, Maroon Dam on southern Darling Downs had received just over 50mm of rain in an hour, and hail was reported in Legume on the Queensland-NSW border.It was predicted to affect Boonah, the area between Boonah and Beaudesert and the area northeast of Kingaroy at 5:25 p.m. and Beaudesert, Laidley and Gatton at 5:55 p.m.
By noon it was hot in Queensland and the heatwave en conditions caused temperatures in the central west of the state to rise above 40 ° C.
The hottest place in Queensland is currently Longreach with 40.5 ° C at noon, followed by Blackall at 39.9 ° C and Rockhampton and Blackwater at 38 ° C.
It comes after Southeast Queensland was treated to a nightly lightning show as the state swells from a final summer heat wave.
While only 18mm fell overnight in Brisbane, a lightning bolt lit the sky around 11 p.m., captured by Twitter users, some of whom were woken by the storm.
A stunning light show will sweep through most of Southeast Queensland tonight. This bolt was pointed west from Coorparoo, where it was just beginning to rain, as the thunder builds up @ 10NewsFirstQLD # bnestormpic.twitter.com/Aj3bDaQ9M8
Most of the rainfall was recorded in Goonburra south of Toowoomba at 34mm. Eagle Farm near Brisbane Airport received 18mm in the night storage hall.
A record day followed in Queensland, when Rockhampton experienced its hottest February day since 1969 with 41.4 ° C and nine degrees above average.
Bundaberg reached 38.6 ° C, well above the 30 ° C average. Gatton, west of Brisbane, recorded 40.4 ° C, nine degrees above average.
James Thompson, forecaster of the Bureau of Meteorology said a low pressure system over the Tasman Sea was responsible for the heat wave.
« This has been dragging hot air from Central Australia to East Queensland in the last few days, which is why we saw heat wave conditions, » he said.
« See you Tuesday another warm day in much of Queensland Starting tomorrow in East Queensland.
Mr Thompson said there is a « chance » of more storms on Tuesday afternoon, more likely through the Darling Downs and western parts of the Southeast.
« There is definitely that Possibility of the storm reaching the coast today, but whether it will hit Brisbane is difficult to say, « he said.

Using a new satellite-based method, scientists at NASA, Environment and Climate Change Canada, and two universities have located 39 unreported and major human-made sources of toxic sulfur dioxide emissions.
A known health hazard and contributor to acid rain, sulfur dioxide (SO2) is one of six air pollutants regulated by the U.S. Environmental Protection Agency. Current, sulfur dioxide monitoring activities include the use of emission inventories that are derived from ground-based measurements and factors, such as fuel usage. The inventories are used to evaluate regulatory policies for air quality improvements and to anticipate future emission scenarios that may occur with economic and population growth.
But, to develop comprehensive and accurate inventories, industries, government agencies and scientists first must know the location of pollution sources.
"We now have an independent measurement of these emission sources that does not rely on what was known or thought known," said Chris McLinden, an atmospheric scientist with Environment and Climate Change Canada in Toronto and lead author of the study published this week in Nature Geosciences. "When you look at a satellite picture of sulfur dioxide, you end up with it appearing as hotspots - bull's-eyes, in effect -- which makes the estimates of emissions easier."
The 39 unreported emission sources, found in the analysis of satellite data from 2005 to 2014, are clusters of coal-burning power plants, smelters, oil and gas operations found notably in the Middle East, but also in Mexico and parts of Russia. In addition, reported emissions from known sources in these regions were -- in some cases -- two to three times lower than satellite-based estimates.
Altogether, the unreported and underreported sources account for about 12 percent of all human-made emissions of sulfur dioxide - a discrepancy that can have a large impact on regional air quality, said McLinden.
The research team also located 75 natural sources of sulfur dioxide -- non-erupting volcanoes slowly leaking the toxic gas throughout the year. While not necessarily unknown, many volcanoes are in remote locations and not monitored, so this satellite-based data set is the first to provide regular annual information on these passive volcanic emissions.
"Quantifying the sulfur dioxide bull's-eyes is a two-step process that would not have been possible without two innovations in working with the satellite data," said co-author Nickolay Krotkov, an atmospheric scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
First was an improvement in the computer processing that transforms raw satellite observations from the Dutch-Finnish Ozone Monitoring Instrument aboard NASA's Aura spacecraft into precise estimates of sulfur dioxide concentrations. Krotkov and his team now are able to more accurately detect smaller sulfur dioxide concentrations, including those emitted by human-made sources such as oil-related activities and medium-size power plants.
Being able to detect smaller concentrations led to the second innovation. McLinden and his colleagues used a new computer program to more precisely detect sulfur dioxide that had been dispersed and diluted by winds. They then used accurate estimates of wind strength and direction derived from a satellite data-driven model to trace the pollutant back to the location of the source, and also to estimate how much sulfur dioxide was emitted from the smoke stack.
"The unique advantage of satellite data is spatial coverage," said Bryan Duncan, an atmospheric scientist at Goddard. "This paper is the perfect demonstration of how new and improved satellite datasets, coupled with new and improved data analysis techniques, allow us to identify even smaller pollutant sources and to quantify these emissions over the globe."
The University of Maryland, College Park, and Dalhousie University in Halifax, Nova Scotia, contributed to this study.

What's New in Version 1.4
Today Weather v1.4 sports some subtle but welcome iOS 7 visual enhancements, most noticeable on the forecast and today views. Enjoy! :)
Great visual tweaks to my favorite weather app!
Today Weather really deserves more coverage by major sites, because this app is wonderful! I love the presentation of the today screen but it's the weekly forecast page that keeps me coming back; there's a style there that no other weather app matches.
I'm very glad to see them make the subtle and slight changes needed to bring the app in more of an "iOS 7-esque" design, both because the more matte look is really nice, and because it shows that the developers haven't given up on updating the app. Great work, guys!
Nice app, add wind prections
As a distance runner, I rely heavily on weather apps to plan my daily runs. I can't take a chance that I'll be out there for 2 hours and may run into unexpected lightning storms or heavy winds. I have always used The Weather Channel's app for their comprehensive forecasting, but have been looking for a more visually appealing app. I LOVE the Today Weather app but would be thrilled if the developers would add hourly wind predictions. Add wind predictions and I'll give ya 5 stars!
Lots on info, innovative views for multiple locations, hi-low temps, hourly forecast. Like it much better than Apple's weather app, Yahoo, or The Weather Channel. My default weather app.

Drama is in the details: Even though I knew today's temps here in Toronto were going to be high, hearing the weather report just now on the radio made me think, "really?... that high?"
We Torontonians plan today to swim in a predicted temperature of 32 degrees Celsius; or 90 degrees Fahrenheit. Not bad in itself but the "Humidex" (humidity index) is expected to be 41 Celsius; or 106 Fahrenheit.
As a friend of mine from Columbia says, "... but not this hot!" (It's the high humidity that kills him.)
At any rate, let's enjoy it while we can; both the U.S. Weather Service and Environment Canada are predicting a "harsh winter"... courtesy of the "Polar Vortex".

03 Feb Friday Flashback – December Monster
Welcome to the first in a series of “Friday Flashback” posts from past Storm Warriors Storm chases.
We’ve been asked before, when is “tornado season”? While the answer you’d expect to hear is “spring time”, which does have the most amount of tornadoes, the truth is tornadoes can happen any time of year if the ingredients are right. This was such an occasion.
There was still a lot of warm gulf air that December morning and with a cold front sweeping in to meet that cold air, we had a classic setup for the potential of tornadic supercells around the Mississippi River Delta regions along the river from Tennessee to Louisiana.
We had decided to setup just east of the river. There are only a few crossings along about a 100 mile stretch and these storms would be moving at a good pace, we didn’t want to get stuck on the wrong side of the river. We setup in Clarksdale, MS and waited. The first storms of the day formed just north of us and became tornado warned. Still we waited for an area just to our southwest that had the best ingredients for tornadic supercells. This tornado literally formed to our southwest and tracked directly at us for at least 15 minutes or more.
We ran around to some houses around us to knock on doors and alert the residents of the impending tornado. We also hit our “train” horn while re-positioning east to alert the area around us. I distinctly remember a resident coming out on to his porch as we drove by to see what all the commotion was about, seeing the tornado, then running back inside his house to take shelter. We came back to the same area shortly after the tornado went through and had a couple of people tell us they heard us come by and that’s what alerted them to the tornado as this was a mostly rural area, some of which did not have tornado sirens. Our live feed was on CNN and The Weather Channel as well.
This tornado became an EF-3 and tracked more than 60 miles before lifting and setting back down an even larger monster, an EF-4 that tracked for 70+ miles. This was easily the most intense winter tornado I’ve ever witnessed.
Don’t ever assume that tornadoes can’t happen because of what the calendar says. Tornadoes do not follow a calendar. Have a plan. Know where to go. And stay safe!


A stunning aurora above Jupiter’s North Pole has been captured by the Hubble telescope.
The image of the Northern Lights was taken ahead of the arrival of Nasa’s spaceship Juno next week which will spend a year monitoring the largest planet in the Solar System.
Jupiter is known for its colourful storms such as the Great Red Spot which swirls constantly in the planet’s atmosphere. But it’s powerful magnetic field also means it has spectacular light shows at its poles.
Just like on Earth, auroras are created when high energy particles enter a planet's atmosphere near its magnetic poles and collide with atoms of gas.
"These auroras are very dramatic and among the most active I have ever seen", said Jonathan Nichols from the University of Leicester, UK, and principal investigator of the study.
"It almost seems as if Jupiter is throwing a firework party for the imminent arrival of Juno."
To highlight changes in the auroras Hubble is observing Jupiter daily for around one month.
Using this series of images it is possible for scientists to create videos that demonstrate the movement of lights at the poles, which cover areas bigger than the Earth.
Not only are the auroras huge, they are also hundreds of times more energetic than auroras on Earth.
And, unlike those on Earth, they never cease. Whilst on Earth the most intense auroras are caused by solar storms -- when charged particles rain down on the upper atmosphere, excite gases, and cause them to glow red, green and purple -- Jupiter has an additional source for its auroras.
The strong magnetic field of the gas giant grabs charged particles from its surroundings, including particles thrown into space by its orbiting moon Io, known for its numerous and large volcanos.
Nasa’s Juno mission, which arrives at Jupiter’s orbit on July 4, aims to discover if a solid core lies beneath the dense athmosphere and what it driving the intense magnetic vield.
The 3.5 tonne spacecraft was launched in 2011 and it will be the first probe to travel so close to Jupiter’s deadly radiation belts.

Hills overlooking Manali get snow again
Shimla, Feb 6 (IANS) Hills overlooking Himachal Pradesh`s picturesque tourist resort of Manali saw another spell of snowfall Sunday but the entire state has been experiencing unusually high temperatures.
"The minimum temperature in the state recorded Sunday was four to seven degrees above the average for this time of the year mainly due to partly cloudy skies," a met department official said here.
The hills in upper Manali have been experiencing intermittent snowfall since early Sunday morning. "The entire higher reaches in Lahaul and Spiti, Kinnaur, Kullu and Chamba districts have been getting snow," he added.
Meanwhile, Shimla recorded a low of 8.1 degrees Celsius, seven degrees above average.
Keylong, some 250 km from Manali, was the coldest place in the state with a low of minus 5.4 degrees Celsius, four degrees above normal.
Kalpa in Kinnaur district saw the night temperature at 0.6 degree Celsius, four degrees above average while it was 9.5 degrees at Bhuntar, seven degrees above average.
Dharamsala recorded a low of 4.7 degrees Celsius.

MOBILE, Ala. – Twisters hopscotched across the Deep South, and, along with brutal, straight-line winds, knocked down countless trees, blew the roofs off homes and left many Christmas celebrations in the dark.
As predicted, conditions were volatile throughout the day and into the night with tornado warnings still out for some parts of Alabama. The storms were blamed for three deaths, several injuries, and left homes from Louisiana to Alabama damaged.
In Mobile, Ala., a tornado or high winds damaged homes, a high school and church, and knocked down power lines and large tree limbs in an area just west of downtown around nightfall. WALA-TV’s tower camera captured the image of a large funnel cloud headed toward downtown.
Rick Cauley, his wife, Ashley, and two children were hosting members of both of their families. When the sirens went off, the family headed down the block to take shelter at the athletic field house at Mobile’s Murphy High School.
“As luck would have it, that’s where the tornado hit,” Cauley said. “The pressure dropped and the ears started popping and it got crazy for a second.” They were all fine, though the school was damaged. Hours after the storm hit, officials reported no serious injuries in the southwestern Alabama city.
Meanwhile, blizzard conditions hit the nation’s midsection.
Earlier in the day, winds toppled a tree onto a pickup truck in the Houston area, killing the driver, and a 53-year-old north Louisiana man was killed when a tree fell on his house. Icy roads already were blamed for a 21-vehicle pileup in Oklahoma, and the Highway Patrol there says a 28-year-old woman was killed in a crash on a snowy highway near Fairview.
The snowstorm that caused numerous accidents pushed out of Oklahoma late Tuesday, carrying with it blizzard warnings for parts of northeast Arkansas, where 10 inches of snow was forecast. Freezing rain clung to trees and utility lines in Arkansas and wind gusts up to 30 mph whipped them around, causing about 71,000 customers to lose electricity for a time.

As Hurricane Dorian gets closer to Florida, U.S. Geological Survey scientists have been in the field from Savannah, Georgia to Hollywood, Florida and on Florida’s Gulf Coast, deploying 175 storm-tide sensors [video] and16 other instruments that will track the hurricane’s effects.
Between Thursday, August 29 and Saturday, August 31, hydrologists from the USGS’ Caribbean-Florida Water Science Center installed 125 storm-tide sensors in Florida. Eighty-five are in place along the state’s Atlantic coast from the Florida-Georgia state line to southern Broward County.
On Friday, field crews installed 40 more on Florida’s Gulf Coast. Additional Gulf Coast deployments were curtailed on Saturday, after National Hurricane Center forecasters predicted Dorian would likely remain off the state’s Atlantic coast. But the sensors installed at Captiva and Cape Coral, from Spring Hill to Sarasota, and from north of Steinhatchee to Inglis will remain in place until after the storm has passed.
In Georgia, field scientists are installing 50 storm-tide sensors the length of the state’s low-lying coastline. Slow-moving Hurricane Dorian may cause higher-than-normal ocean waves well to the north of the storm, and its course is still uncertain.
Most of the instruments are designed to measure the height and duration of the storm-tide as the storm approaches shore, makes landfall, and departs. Others will monitor water levels on inland water bodies, with some reporting water level data in near real-time; the field crews will gather data from them immediately after the storm has passed. The USGS’ Flood Event Viewer for Hurricane Dorian shows the location of the instruments that will record the storm’s effects on water levels as it moves onshore.
Storm surge, coastal erosion and inland flooding are among the most dangerous natural hazards unleashed by hurricanes, with the capacity to destroy homes and businesses, wipe out roads, bridges, water and sewer systems, and profoundly alter landscapes. The USGS has storm surge experts, as well as sophisticated equipment for predicting and monitoring flood and tide conditions, and has been consulting with the National Hurricane Center and other agencies to prepare for Hurricane Dorian.
Prepared to Capture Coastal Storm Surges
Storm surges are increases in ocean water levels caused by extreme storms. Scientists want to better understand storm surges so forecasters can more accurately model and predict surge-related flooding, engineers can design better storm-resistant structures, and emergency responders can work more safely and effectively.
The USGS’ network of storm tide sensors along portions of the U.S. Atlantic and Gulf coasts can record water level and barometric pressure every 30 seconds to document storm surge crests, or waves of water, as they make landfall. Anticipating a storm’s path and intensity, USGS scientists often deploy storm tide sensors at other places along the coast just hours or days before a hurricane’s expected landfall. The sensors are housed in steel pipes a few inches wide and about a foot long. Working quickly, and often in severe weather, field crews install them on bridges, piers and other structures that have a good chance of surviving a hurricane’s storm surge.
The teams are also deploying barometric pressure sensors, one within ten miles of every storm tide sensor; the two devices work together to correlate the storm’s intensity with wave heights. The crews also plan to deploy five clusters of wave height sensors on boardwalks in Flagler, Volusia, Brevard, St. Lucie and Palm Beach counties. By recording wave heights along a line running from the beach to the dune peak and behind the dune, these transects help create a detailed picture of wave action.
Adding Temporary Streamgages to Track Dorian
The USGS Streamgaging Network operates scientific instruments that record water levels and other key pieces of information on rivers and streams throughout the nation, with the support of local, state, and federal agencies. During storms and floods the USGS uses this nationwide network to provide near-real-time data about water levels to the National Weather Service, Federal Emergency Management Agency, the U.S. Army Corps of Engineers, and others.
When a major hurricane is expected to make a U.S. landfall, the USGS augments the network by installing special streamgages called rapid deployment gauges, or RDGs, in areas where flooding is likely, but no permanent streamgage exists. RDGs measure water levels and local weather data in areas susceptible to storm-tide flooding and transmit that information by satellite in near-real time for flood forecasting and emergency response. The public can see the information in near-real time by clicking on the RDG symbol in the Flood Event Viewer.
Field crews have installed eight RDGs in Florida. They plan to install 12 RDGs in Georgia, completing the work in advance of Hurricane Dorian’s winds, rain and storm waves. If flooding does occur, USGS field crews will make real-time streamflow measurements to verify the streamgages’ readings. After the storm passes, the crews will quickly replace any storm-damaged or lost gauges. During and right after hurricane flooding, these records help FEMA target emergency relief to the hardest-hit areas.
Resources to Help Everyone Prepare
As USGS takes action to prepare for Hurricane Dorian, people in the path of the storm can get tips on creating emergency plans and putting together an emergency supply kit at www.ready.gov or www.listo.gov.


SALINAS VALLEY — Local emergency officials have issued an excessive heat warning this weekend for parts of Monterey County, including the cities of Greenfield and King City as well as southern Salinas Valley.
The warning takes effect beginning at 12 p.m. Friday and continues until 11 p.m. Sunday, according to the Monterey County Office of Emergency Services.
Dangerously hot conditions are expected, with temperatures ranging from 102 to 110 degrees. Overnight temperatures will also remain very warm, mostly in the mid-70s to mid-80s in the higher elevations.
Other areas under the advisory are Arroyo Seco, Lake San Antonio, Santa Lucia Mountains, Los Padres National Forest and interior Monterey County, including Pinnacles National Park.
“The hottest temperatures are expected in the mountains of San Benito and Monterey counties, the far southern end of the Salinas Valley, and the mountains of northeastern Napa and Sonoma counties,” stated the National Weather Service (NWS) in an alert.
Prolonged exposure to hot temperatures can increase risk of heat-related illnesses, such as heat exhaustion and heat stroke. According to NWS, people most vulnerable include those who spend extended periods outdoors, those without air conditioning, young children, the elderly and those with chronic illness.
“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” the NWS advised. “Young children and pets should never be left unattended in vehicles under any circumstances. Take extra precautions if you work or spend time outside.”
King City Recreation Center at 401 Division St. will be open as a Cooling Center on Saturday and Sunday, July 10 and 11, from 11 a.m. to 4 p.m. The King City pools and the splash pad at City Park are also available, the city announced.


Heads up, stargazers. The Lyrid meteor shower is here and it’s going to reach peak activity this Easter.
The Lyrid meteor shower takes place between April 16 and April 25, and will peak on the night of April 22.
Those in the Northern Hemisphere are best situated for glimpsing a few meteors, but the event should also be visible in the Southern Hemisphere between midnight and dawn. As with any meteor shower, you should find a dark area, far away from city lights, and stay outside for around 20 to 30 minutes to allow your eyes to become adjusted to the low light.
As far as meteor showers go, the Lyrids are not the most lively and dramatic. Visibility might also be hampered by moonlight, as April 23 will also see a bright gibbous Moon, which is very close to a full Moon.
That said, the Lyrid meteor shower is often visible to the naked eye and you can expect to see anything from five to 20 meteors per hour. Plus, given the time of year, many parts of the world should be enjoying relatively clear skies (with a bit of luck).
The Lyrids get their name from the fact they appear to radiate from the area of the sky near the constellation Lyra, whose brightest star is Vega, some 25 light-years away. However, don’t let that distract you as the meteors can appear anywhere in the sky.
The meteors come from debris flying off the tail of comet C/1861 G1 (Thatcher) at speeds of 49 kilometers (30 miles) per second. As these chunks of cosmic dust hit Earth’s atmosphere, they will burn up and leave a streaking tail.
People have been enjoying the Lyrids for at least 2,700 years. They were first written about by Zuo Qiuming, a Chinese writer and contemporary of Confucius, in 687 BCE who described "stars that fell like rain." So who knows, perhaps China's most influential philosopher was an admirer of the Lyrids too.
The Lyrids also play an important role in the astronomical traditions of an Aboriginal Australian group known as the Boorong clan. This clan no longer exists in its singular form and their traditions were only transferred through the ages orally, but we do know that to them, the Lyrids represented the scratchings of the malleefowl bird, represented by the star Vega, during its period of cosmic nest-building.


FAIRFIELD COUNTY, Conn. -- Showers and thunderstorms will likely make for a soggy start to the weekend for Fairfield County, according to the National Weather Service.
Showers will become more likely after noon on Saturday with mostly cloudy skies, humid conditions and a high near 86 degrees. Chance of rain is 70 percent in the steamy weather.
Showers will exit the region overnight, making way for a sunny Sunday with temperatures in the high 70s.

Fog coats morning commute in Bay Area, warm weather expected for weekend
Updated 7:47 am, Friday, January 12, 2018
Heavy fog rolled into parts of the Bay Area Friday morning, limiting visibility for drivers on the morning commute — but it should burn off by late morning and give way to sunny skies for the long weekend.
“We have patchy fog throughout the San Francisco Bay Area, and when it turns patchy, it’s hit or miss,” said Charles Bell of the National Weather Service in Monterey. “Some communities are getting it and some are not, like Oakland is down to two miles of visibility whereas further south near SFO, there’s eight miles.”
Bell urged drivers to use caution on the morning commute in areas with low visibility.

Traffic has so far been light around the Bay Area, said California Highway Patrol Officer James Evans. “There was a collision in the Redwood City are, but otherwise, traffic is moving pretty normally,” Evans said.
The fog should burn off before lunchtime, Bell said, and give way to sunny skies for the next couple of days.
“Today through Martin Luther King Day, we are expecting very nice weather with comfortable temperatures and no chance of any rain,” Bell said.
Temperatures should be in the 60s throughout the Bay Area — likely the high 60s further south — and Sunday is expected to be the warmest day. Winds should be fairly light, Bell said.
“The next chance of rain will be coming in on Tuesday,” Bell said.

(WBBM NEWSRADIO) -- Students at Kenwood Academy High School sat through classes in the cold Tuesday after the school’s heating system broke down on a day of record-breaking freezing temperatures.
Crews were working to fix an equipment failure in the heating system at the school, 5015 S. Blackstone Ave., according to a Chicago Fire Department spokesman.
“This morning, we became aware that one of our motors failed, which resulted in our school losing heat circulation,” Chicago Public Schools said in a letter to parents of the school.
No one was evacuated, and crews with CPS’s building department were working on the issue, the spokesman said.
School officials said they checked temperatures in the school multiple times throughout the day and determined them to be safe. Heat was restored just after 4 p.m. Tuesday.\
The heater failure at Kenwood came on a day of record cold in Chicago.
By midday, the temperature in Chicago was 17 degrees, with a wind chill of 5 degrees, according to the National Weather Service.
With an expected high of 18 degrees on Tuesday, Chicago should shatter the previous “lowest high” temperature of 28 set in 1995, the weather service said.
A recorded temperature of 7 degrees at O’Hare Tuesday morning broke a record low set in 1986, the weather service said.


Flooded avenues, collapsing houses, landslides … The torrential rains that have hit the Recife region since Tuesday, capital of the state of Pernambuco (northeastern Brazil), have caused at least 34 dead, including 29 in the last 24 hours, according to a latest Civil Defense report, Saturday May 28.
More than 1,300 people have lost their homes due to this situation. The most serious accident occurred early Saturday, when 19 people perished in a “major landslide” in Jardim Monteverde. Six other people were killed in another landslide in the municipality of Camaragibe. Two died in Recife and another in Jaboatao dos Guararapes.
President Jair Bolsonaro expressed on Twitter his “condolences and solidarity with the victims of this sad disaster”.
Between Friday evening and Saturday morning, rainfall reached 236 millimeters in parts of the Pernambuco capital, according to the town hall. That equates to more than 70% of the city’s entire May rainfall forecast. According to the Pernambuco water and climate agency, the situation could worsen as the rains will continue for the next 24 hours in the state.
Many cities near Recife are also suffering from the rains.

Over the past year, hundreds of Brazilians have died in floods and landslides caused by heavy rains. In February, more than 230 people were killed in the city of Petropolis, the former capital of the Empire of Brazil in the 19th century, in the state of Rio de Janeiro.
By making the atmosphere warmer and also wetter, global warming increases the risk and intensity of flooding caused by extreme precipitation.


Weather warnings remained in place across much of France on Thursday including in the French Alps, where the threat of avalanches is high and skiers in certain stations have been left cut off due to the extreme weather.
Storm Eleanor blew through France on Wednesday leaving one dead, 15 injured and 225,000 homes without power, scores of roads blocked and flights and train services severely disrupted.
By Thursday some 21 departments around the country were still on alert for various reasons.
Around the French coast it was the likelihood of high waves and flooding caused by strong winds and the high tides that meant orange alerts were in place.
While in the French Alps it was the threat of avalanches and high winds that meant orange alert warnings remained (see map below).
In Normandy and parts of the east of the country there remained a risk of flooding.
Around the coast the country's weather agency Météo France warned of abnormally high sea levels due to winds and high tides that will leave parts of the coast submerged. The public are advised to stay away from the water's edge.
Avalanche warnings are in place in part of the Alps including the Mont Blanc range due to heavy snow in recent days. The departments of Haute-Savoie, Savoie, Isère and Hautes -Alpes were on alert with the avalanche risk at level 5 – the highest – in many ski resorts.
"We have all the elements that could see avalanches, floods and landslides," one Alps firefighter told Europe 1 radio.
France's interior ministry has warned skiers to take maximum precautions to stay safe with Météo France warning that avalanches could be triggered at anytime in any place due to the heavy snow.
Many of the higher ski stations in the Alps were closed on Wednesday due to the high winds which reached 150km/h high up the slopes. Many remained closed on Thursday.
At Val Thorens, Europe's highest ski station the 20,000 skiers staying in the resort were cut off from the world on Wednesday night after the access road from Les Menuires was closed.
The pistes remain closed due to the risk of avalanches with officials taking preventative measures to reduce the risk.
On Wednesday a skier in the Alps resort of Morillon was killed when he was hit by a tree blown over on to the piste in high winds.


Floridians were treated to a bizarre sight over the weekend when a bright fireball suddenly appeared streaking across the evening sky.
The American Meteor Society (AMS) said it has received more than 200 reports from people in four different states, including Florida, regarding a ball of light seemingly burning in the sky overhead.
The non-profit scientific group believes the scene was likely caused by a meteor entering the Earth's atmosphere near Tallahassee, Florida. It is still unknown whether the space rock burned up completely upon entry or if it was able to hit the surface of the planet.
A Bright Fireball In The Sky
Witnesses claimed the fireball that appeared midnight Saturday burned so brightly that it created shadows for several seconds before eventually fizzling out.
Eric Shultz, one of the Floridians who saw the event, posted on local TV station WMBB-TV's Facebook page. He said they saw a strange light falling from the sky over Youngstown. The scene was caught on video by their home's doorbell camera.
Meanwhile, Jacksonville resident Jeffrey Cardona asked others via Twitter if they also saw the fireball. He was able to capture the scene on his car's dashboard camera.
"Can somebody explain this," Cardona wrote.
A YouTuber said they witnessed the fireball while on their way. They described the event as "pretty crazy."
Meteor Falling On Earth
The National Weather Service (NWS) detected the falling meteor as well. The fireball's flash was recorded using the Geostationary Lightning Mapper satellite, which is used to take photographs of lightning storms to help map their paths across the country.
Haley Brink, a meteorologist working for CNN, said meteors such as the one seen over the weekend happen quite fairly. However, people do not get to witness them all the time.
She explained that these scenes are starting to become more visible to the public these days courtesy of satellites in space, as well as various cameras here on Earth.
The NWS said it received unconfirmed reports of the meteor crashing somewhere near Perry, Florida. The city is located about 55 miles southeast of Tallahassee.
Experts advised residents who may come across fragments of the meteor that tests would have to be undertaken to confirm that it is indeed the space rock.
This is not the first Earth received a sudden visitor from outer space. Earlier this year, a meteor was seen burning up in the sky over western Cuba, with some pieces of the space rock reaching the ground. There were no reported cases of people getting hurt in the incident, but the explosion was said to have been heard as far away as Florida.
In August, NASA's Jet Propulsion Laboratory reported that a meteor crashed in Greenland with a 2.1 kiloton blast. The space rock hit the ground 43 kilometers north of the United States Air Force's Thule Air Base.
Hans Kristensen, director of the Nuclear Information Project for the Federation of American Scientists, posted about the explosion on Twitter. However, the American military did not confirm the space rock's crash.
Kristensen raised his concern about the U.S. government's failure to issue a warning to the public regarding the meteor.

No signs of life on Venus despite strange behaviour of sulphur in atmosphere
The long-held belief that life could exist in Venus’ clouds has been rejected by a new study, which claims that sulfur’s unusual behavior in the atmosphere cannot be explained by an “air” form of aliens.
Any life form in sufficient abundance is expected to leave chemical fingerprints on a planet’s atmosphere as it consumes food and expels waste.
But scientists at the University of Cambridge found no evidence of this, after using a combination of biochemistry and atmospheric chemistry to test the “life in the clouds” hypothesis.
Astronomers have speculated for decades that sulfur in the clouds of the sun’s second planet could support life and act as a potential food source.
However, researchers said “air” life cannot explain the makeup of Venus’ atmosphere and why sulfur is “sucked” from the air.
“We wanted life to be a possible explanation, but when we ran the models, it turned out not to be a viable solution,” said lead author Sean Jordan of the Cambridge Institute of Astronomy.
The belief that life could exist in Venus’ clouds has been rejected by a new study, which claims that sulfur’s unusual behavior in its atmosphere cannot be explained by an “air” form of aliens. Pictured is an artistic impression of what microbial life might look like
VENUS: THE BASE
Venus, the second planet from the sun, is a rocky world about the same size and mass as Earth.
However, the atmosphere is radically different from ours: It consists of 96 percent carbon dioxide and has a surface temperature of 464 °C and a pressure 92 times that on Earth.
The inhospitable planet is shrouded in clouds of sulfuric acid that make its surface impossible to glimpse.
It has been suggested in the past that Venus probably had oceans similar to Earth’s — but these would have evaporated when it underwent a runaway greenhouse effect.
The surface of Venus is a dry desert landscape, which changes periodically due to volcanic activity.
Facts and numbers
Turnaround time: 225 days
Surface: 460.2 million km²
Distance from Zon: 108.2 million km
Duration of the day: 116d 18h 0m
Ray: 6,051.8 km
Mass: 4.867 × 10^24 kg (0.815 M⊕)
Their models looked at a special feature of the dense atmosphere, namely the abundance of sulfur dioxide (SO2).
On Venus — the brightest natural object in Earth’s night sky after the moon — there are high levels of SO2 lower in the clouds, but it’s somehow “sucked out of the atmosphere” at higher elevations, the report said. scientists.
On Earth, most SO2 in the atmosphere comes from volcanic emissions.
dr. Oliver Shorttle of Cambridge’s Department of Earth Sciences and Institute of Astronomy and a co-author of the study, said: ‘If life is present, it must influence atmospheric chemistry.
“Could life be the reason SO2 levels on Venus are being reduced so much?”
Researchers used a combination of atmospheric and biochemical models to study the expected chemical reactions, given the known sources of chemical energy in Venus’ atmosphere.
The models contain a list of metabolic reactions that the life forms would carry out to obtain their ‘food’, and the waste by-products.
Scientists have used the model to see if the reduction in SO2 levels can be explained by these metabolic reactions.
They found that the reactions can result in a drop in SO2 levels, but only by producing other molecules in very large quantities that are not seen.
The results suggested a hard limit to how much life could exist on Venus without blowing apart our understanding of how chemical reactions work in planetary atmospheres.
“We looked at the sulfur-based ‘food’ available in Venus’ atmosphere — it’s not something you or I would want to eat, but it’s the main source of energy available,” Jordan said.
“If that food is being consumed by life, we should see evidence of it by specific chemicals being lost and gained into the atmosphere.
“If life were responsible for the SO2 levels we see on Venus, it would also break everything we know about Venus’ atmospheric chemistry.
“But if life isn’t responsible for what we see on Venus, it’s still a problem to be solved — there’s a lot of strange chemistry to follow up on.”
While there’s no evidence of sulphur-eating life hiding in Venus’ clouds, the researchers said their method of analyzing atmospheric signatures will be valuable when NASA’s $10 billion (£7.4 billion) James Webb Space Telescope (JWST) will begin returning images from other planetary systems later this year.
Some of the sulfur molecules in the current study are easy to spot with JWST, so learning more about our neighbor’s chemical behavior could help scientists find similar planets in the galaxy.
dr. Shorttle said, ‘To understand why some planets are alive, we need to understand why other planets are dead.
For nearly 50 years, experts have been baffled by the presence of ammonia, a colorless gas made of nitrogen and oxygen, which was tentatively detected in the atmosphere of Venus in the 1970s.
“If life could somehow sneak into the Venusian clouds, it would totally change the way we look for chemical signs of life on other planets.”
Even if Venus has no life, the researchers said their results could be useful for studying the atmospheres of similar planets in the galaxy and the eventual detection of life outside our solar system.
dr. Paul Rimmer, of Cambridge’s Department of Earth Sciences and Cavendish Laboratory, as well as a co-author of the study, said: ‘We have spent the past two years trying to explain the strange sulfur chemistry we see in the clouds of Venus.
“Life is pretty good at weird chemistry, so we explored whether there’s a way to make life a possible explanation for what we see.
Even if ‘our’ Venus is dead, it is possible that Venus-like planets in other systems harbor life.
“We can take what we’ve learned here and apply it to exoplanetary systems — this is just the beginning.”
The study is published in the journal nature communication†
CARBON DIOXIDE AND SULFURIC ACID DROPS IN THE ATMOSPHERE OF VENUS
The atmosphere of Venus is mostly carbon dioxide, with clouds of sulfuric acid droplets.
The thick atmosphere traps heat from the sun, resulting in surface temperatures over 470 °C (880 °F).
The atmosphere has many layers with different temperatures.
At the level of the clouds, about 50 km above the surface, it is about the same temperature as on the Earth’s surface.
As Venus moves forward in its orbit around the sun as it slowly spins backward on its axis, the highest level of clouds zips around the planet every four Earth days.
They are powered by hurricane-force winds at about 224 miles (360 km) per hour.
Atmospheric lightning bolts illuminate these fast-moving clouds.
Speeds in the clouds decrease with the height of the clouds, and on the surface they are estimated to be only a few miles (km) per hour.
On the ground, it would look like a very hazy, cloudy day on Earth, and the atmosphere is so heavy it’s like you’re a mile deep under water.


On September 18, Hurricane Maria evolved from a category 1 storm to a category 5 storm in less than 18 hours, just before it slammed the Caribbean island of Dominica (Source: NASA). It thrashed the country with extreme winds and rain and destroyed all in its path. At the time of landfall, sustained winds, which were reported to be 260 km/h, affected the entire population.
This is the fifth time on record that Dominica has taken a direct hit from a hurricane, but never has it faced a storm of such ferocity and strength. The hurricane brought life in Dominica to a standstill.
Hurricane Maria caused widespread damage and destruction in Dominica, one of the poorest countries in the Eastern Caribbean. On September 25, the UN estimated that the entire population suffered direct damage to housing and livelihoods.
Food and water are the most urgent needs. People lack access to fresh running water due to damaged pipes in many parts of the country. The hurricane also caused widespread damage to the power grid, leaving the entire country without electricity.
Communication towers on hilltops were snapped in two, causing an island-wide communications blackout. The cellular network has since been unreliable throughout the country. The majority of the roads are blocked with debris and many of the bridges are damaged.

Weather service scales back Seattle snow forecast
SEATTLE - January 18, 2012 (WPVI) -- As snow started falling on Seattle Wednesday morning, the National Weather Service scaled back the amount expected in western Washington but said it would still be a significant event.
Meteorologist Dustin Guy says the total in the city would likely be 3 to 6 inches. More is likely in southwest Washington - 4 to 8 inches. While less is expected in the northwest interior - 1 to 2 inches.
On Tuesday, forecasters had been talking about 5 to 10 inches in the central Puget Sound region, 6 to 14 inches in southwest Washington and 2 to 5 in the northwest interior.
Guy says the mountains will still get heavy snow - up to 2 feet by Thursday.
Widespread snow is forecast across eastern Washington.

UPDATED: New, violent storms were rolling over large portions of Norway this week, also after meteorologists had declared that the weekend’s storm was over. Winds were so strong during the night that portions of the roof blew off the football stadium in Ålesund as the northwest coast took a pounding.
Western Norway was still getting hit the hardest on Tuesday, from Sørlandet beyond Hordaland as stormy weather slammed into the counties of Sogn og Fjordane and Møre og Romsdal Monday night and into Tuesday. More storm systems were on the way, according to the meteorologists.
The extreme weather system “Nina” that brought hurricane-force winds during the weekend was said to have made a “U-turn” between Iceland and Northern Norway, bringing more strong winds to coast of Nordland County as well. Warnings were posted for Helgeland, Saltfjellet, Salten and Ofoten on Tuesday.
Ferries were still halted and only two roads connecting eastern and western Norway were open over the mountains of southern Norway on Tuesday morning: State highway 52 over Hemsedal and the E16 over Filefjell. Main routes such as the E134 over Haukefjell and State Highway 7 over Hardangervidda were closed because of strong winds and snowdrifts.
Bergensbanen closed at Geilo
Snowplow drivers simply gave up in some areas of the south on Monday.The situation was no better on Tuesday, with some areas lying under as much as 2.5 meters (more than eight feet) of snow.
Train lines were also affected, with Bergensbanen (the main line between Bergen and Oslo) closed between Geilo and Mjølfjell because of blocked tracks. State railway tried to offer alternative bus service but they’re delayed or halted as well because of closed roads.
Thousands of households remained without power, especially in Hordaland, and some elderly residents were temporarily moved to local nursing homes because they lacked heat at home.
Many were also without mobile phone and Internet coverage after trees crashed over power and phone lines in the southwest. Telenor confirmed that 68 base stations were knocked out of operation in Hordaland while 16 base stations were down in Vest-Agder, where the storm hit the southern coast hard. Risør was among the towns where communications were severely disrupted.
Highway 45 between Aust-Agder and Telemark remained closed after snow-clearing crews had to give up efforts to move huge mounds of snow. “We could hardly see any road, much less clear it,” one driver told Norwegian Broadcasting (NRK). New attempts were due to be made on Tuesday but more strong wind was expected that could hinder visibility.
The main road out of the popular ski center at Hovden at the northern end of Setesdal was also buried in snow and emergency crews were only allowing convoys of cars through the area.
Calls poured in to insurance companies
The extent of damage caused by the extreme weather system called “Nina” became more clear on Monday with insurance companies reporting “enormous” numbers of calls for help. Emma Elisabeth Vennesland of insurance firm If Skadeforsikring said the firm received 750 calls on Sunday and another 920 by late Monday afternoon.
Hurricane-force winds especially damaged roof construction, while flooding destroyed many wharves and boat houses along the coast from Aust-Agder to Hordaland. Residents were once again warned of flying objects in the air that can be dangerous.
The other end of the country, in the far north, remained in the grip of an extreme cold snap, with temperatures of minus-40C on Monday in Karasjok again. The frigid weather halted school bus and other vehicular traffic in several areas of Finnmark but school officials said they’d only close if temperatures fell to minus-50.
There was some good news, as the sun returned in such northern venues as Lofoten, Harstad and Bardufoss. It was due to rise above the horizon in Tromsø on Thursday and in most of the rest of Northern Norway next week.


We’ve all read about those passages with nothing but weeks of wind aft of the beam and no need to adjust a sheet. No doubt they happen, and when they do, they are also doubtlessly noteworthy. I’m still waiting for one of those myself. In fairness, I guess I should admit that the wind can be consistent when it is strong and my destination is upwind.
Over the last couple of years I have been distributing weather observation forms to cruising yachts, and I’ve gathered enough data to present a short summary of findings.
I summarized the logs by first pulling out the wind observations and listing them. Then each observation is compared with the next one. The idea is that if wind speed is the same, then one probably doesn’t need to change sails. If wind direction is the same, one may need a sail change, but not to alter course. If both are the same, that is the "classic" tradewind passage, at least for as long as it lasts.
Heart of Gold, a Schumacher 50, on a passage between Mopelia and Rarotonga in July 1993, however, showed no constant wind direction over a 72-hour period. It backed or veered constantly between south and west, with excursions through north. Wind speed was constant less than half the time. In this data, wind speed varies continually.
Looking at all of the passage records in which I have compiled for the tropics, watch-to-watch wind speed stayed the same within one Beaufort force factor, or about five knots, 35% of the time; direction, 68% of the time; and both 18% of the time.
This compares with a winter passage back to San Francisco from Hawaii on which there were 14 occasions in 25 days (about one half of the observations) which had wind direction consistent between two or more observations. Variation on one watch of 20 or more degrees occurred in about 20 percent of the observations. The wind speed was equal between observations on seven occasions, comprising about 30% of the data.
The greatest wind speed variation between observations was three Beaufort force factors, but it also varied that much during one observation period 20 percent of the time, and two of the occasions of equal wind speed were force eight. In other words, the variables are more variable.
But on a coastal California passage in summer 1993, with observations every four hours, wind direction was constant in 50% of the observations. The most common direction was NW, 33% of the time. Wind direction and speed were constant in 37% of observations. Richard Henry Dana in Two Years Before the Mast did characterize the northwesterlies of California as a form of tradewind. I suppose that there are rare occasions when one could make a good tradewinds passage without touching a sheet. Normally, though, the passage would be pretty slow because one would be wandering off course a lot of the time, and to make up for the heavy stuff, one would be reefed even when it was light. I knew some people who did a 33-day passage from Moorea to Hawaii that way.
All of this can be put into perspective by looking at some data from the Atlas buoy chain. Atlas buoys were deployed in an array along the equator as a part of the effort to measure El Niño, and to formulate climatic models for tropical and global climate. The Tropical Ocean/Global Atmosphere (TOGA) project is a 10-year international effort started in 1985. TOGA Notes is published quarterly and contains articles with titles like "Assimilation of Sea Level Data into a Primitive Equation Model of the Tropical Pacific."
In one of the more basic pieces, average buoy-observed wind speed for 1987-88 for the eastern tropical Pacific was approximately 11 knots, the bottom of Beaufort force 4, with a standard deviation of about three knots. In other words, two-thirds of the observations are within range of 5 to 17 knots, force 2 to force 5. These data are consistent with the yacht observations. For that matter, the October Pilot Chart of the South Pacific shows a wind rose at two degrees north and 132 degrees west that indicates no calms, and wind from the southeast 59% of the time, and from the east 34% of the time.
For the purpose of navigation by sail, the time scale of variation is more interesting and important than the simple average. The bad news is that unless one is either lucky or very slow, the chances are excellent that one will be changing sail constantly, even in the Trade Winds. The good news is that there are fewer gales and fewer radical changes in wind direction. Those changes in wind speed and direction that one can expect will be about half as frequent as those in the variable wind belt.
