(CNN) The toll that Harvey is taking is staggering.

It dumped an estimated 27 trillion gallons of rain over Texas and Louisiana during a 6-day period, says Ryan Maue of WeatherBell, a weather analytics company.

The rainfall has set a record for the most ever from a landfalling tropical cyclone in the continental US. Estimates put eventual total losses at as much as $75 billion . And the death toll continues to climb everyday.

"The word catastrophic does not appropriately describe what we're facing," said Rep. Sheila Jackson Lee, who represents much of Houston. "We just don't know when it's going to end." </s> Tropical storm Harvey lashed Houston over the weekend, leading to heavy flooding across the city. Several people are reported to have died during the storm and subsequent flooding with many more people needing urgent care and shelter. Texas governor Greg Abbott said the response to the disaster was just beginning in the city </s> HOUSTON, Aug 28 (Reuters) - Floodwaters from Tropical Storm Harvey, which has already killed at least seven people in Texas and was expected to drive tens of thousands from their homes, will likely rise in the coming days, officials warned on Monday as heavy rains continued to pound the U.S. Gulf Coast.

National Guard troops, police officers, rescue workers and civilians raced in helicopters, boats and special high-water trucks to rescue the hundreds of people still stranded in and around Houston, the nation's fourth-largest city.

The storm was the most powerful hurricane to strike Texas in more than 50 years when it came ashore on Friday near Corpus Christi, 220 miles (354 km) south of Houston, and the worst was far from over as the National Weather Service issued numerous flood warnings across the region.

U.S. President Donald Trump plans to go to Texas on Tuesday to survey the damage and may in the future visit Louisiana where the storm is now dumping rain.

Trump, facing the biggest U.S. natural disaster since he took office in January, has signed disaster proclamations for Texas and Louisiana, triggering federal relief efforts.

Harvey has killed at least six people in Harris County, where Houston is located, said Tricia Bentley, a spokeswoman for the county coroner's office, including a man who died in a house fire on Friday night and an elderly woman driving through flooded streets on the city's west side the next day.

A 60-year-old woman died in neighboring Montgomery County when a tree fell on her trailer home while she slept, the local medical examiner said on Twitter. With other people missing, the death toll could rise.

Both of Houston's major airports were shut down, along with most major highways, rail lines and a hospital, where patients were evacuated over the weekend. As of Monday evening 267,000 Texans were left without power in the southeast corner of the state.

One of three main rivers crossing Houston, the Brazos, was expected to crest sometime on Tuesday at 59 feet (18 meters), the National Weather Service said. The San Jacinto River was expected to crest over Interstate 10, the major east-west artery through Houston.

The Harris County Office of Homeland Security and Emergency Management issued a "shelter in place" warning to residents of La Porte and Shoreacres, about 25 miles (40 km) east of Houston, after a chemical leak was caused by a ruptured pipeline.

As stunned families surveyed the wreckage of destroyed homes and roads flooded or clogged with debris, Texas Governor Greg Abbott warned Houstonians to brace for a long recovery.

"We need to recognize this is going to be a new and different normal for this entire region," Abbott said.

Harvey was expected to linger over Texas' Gulf Coast for the next few days, dropping another 10 to 20 inches (25 to 51 cm) of rain, with threats of flooding extending into Louisiana.

In scenes evoking the aftermath of Hurricane Katrina in 2005, police and Coast Guard teams have rescued at least 2,000 people so far, plucking many from rooftops by helicopter, as they urged the hundreds more believed to be marooned in flooded houses to hang towels or sheets outside to alert rescuers.

Harvey's center was about 100 miles (160 km) south of Houston and forecast to arc slowly toward the city through Wednesday, with the worst floods expected later that day and on Thursday.

Schools and office buildings were closed throughout the metropolitan area, home to 6.8 million people, as chest-high water filled some neighborhoods in the low-lying city.

The U.S. Army Corps of Engineers said Monday that it was releasing water from the nearby Addicks and Barker reservoirs into Buffalo Bayou, the primary body of water running through Houston.

"The more they release it could go up and it could create even additional problems," Houston Mayor Sylvester Turner warned. But the release was said to be necessary to prevent an uncontrolled surge of water, which Turner said "would be exponentially worse."

Torrential rain also hit areas more than 150 miles (240 km) away, swelling rivers and causing a surge that was heading toward the Houston area, where numerous rivers and streams already have been breached. About 5,500 people were in shelters as of Monday morning, city officials said, with Federal Emergency Management Agency director Brock Long forecasting that 30,000 would eventually be housed temporarily in shelters.

Regina Costilla, 48, said she and her 16-year-old son had been rescued from their home by a good Samaritan with a boat. She worried until she was reunited with her husband and large dog, who had been left behind because they did not fit into the boat.

"I'm not complaining; we're alive," said Costilla. "When I saw the forecast of the storm I said I'll be happy if we get out with our lives."

In Rockport, National Guard troops passed out water to residents as utility crews worked to restore power in the city, amid reports of sporadic looting.

Houston did not order an evacuation due to concerns about people being stranded on city highways now consumed by floods, Turner said.

Abbott, who had suggested on Friday that people leave the area, declined to second-guess the mayor on Monday, telling reporters, "Decisions about evacuations are something that are behind us."

Gasoline futures hit their highest in two years as Harvey shut down multiple refiners, knocking out about 13 percent of total U.S. refining capacity, based on company reports and Reuters estimates.

Almost half of the U.S. refining capacity is in the Gulf region.

The nation's second-largest refinery was shutdown in Baytown, and the nation's largest refinery in Port Arthur was weighing shutting down with a final decision expected Tuesday, sources told Reuters.

The floods' path of destruction could destroy as much as $20 billion in insured property, making it one of the costliest storms in history for U.S. insurers, according to Wall Street analysts. </s> HOUSTON – There are at least nine deaths in the Houston area resulting from Tropical Storm Harvey.

A family of six is believed to have died after drowning in a white van Sunday afternoon while trying to escape the floods of Hurricane Harvey, relatives tell KHOU 11 News. It is thus far the single deadliest incident resulting from the storm. It happened while crossing a bridge on Green River Road in Greens Bayou.

On Saturday, a spokesman for the Houston emergency operations center said a woman appeared to have gotten out of her vehicle in high water on Werrington near S. Gaston in southwest Houston. She was found by neighbors about 30 yards away from her vehicle. Norman says she was pronounced dead at the scene by a doctor who was in the area, according to the Associated Press.

The sheriff’s office confirmed Monday afternoon a 60-year-old woman was killed when a tree fell on her home as she slept. The incident happened in the 17400 block of Louis Lane in Porter. The victim's husband told authorities he went to get help after the tree crashed into the home because he could not get to her. When authorities got into the home, they found the woman was already dead.

A man between the ages of 60 and 70 reportedly drowned around 11:30 p.m. Monday night. Montgomery County officials said the man was seen trying to swim across the flood waters located at Spring Park Ridge and SH 99. Witnesses tried to help the man after he went into distress. They were however unsuccessful.

Outside of Houston, the first death from Harvey was confirmed in a coastal community in Aransas County. That person died in a fire at a home during the hurricane. Harvey made landfall in Texas on Friday night as a Category 4 hurricane, but it has since been downgraded to a tropical storm as it weakens while inland.

WATER RESCUES: HPD says more than 2,000 rescued from flood waters </s> HOUSTON — A pair of 70-year-old reservoir dams that protect downtown Houston from flooding began overflowing Tuesday, adding to the rising floodwaters from Harvey that have crippled the city after five consecutive days of rain.

Engineers began releasing water from the Addicks and Barker reservoirs Monday to ease the strain on the dams. But the releases were not enough to relive the pressure after one of the heaviest downpours in U.S. history, Army Corps of Engineers officials said. Both reservoirs are at record highs.

The release of the water means that more homes and streets will flood, and some homes will be inundated for up to a month, said Jeff Lindner of the Harris County Flood Control District.

The county is trying to determine where the water will go, Lindner said.

Meanwhile, more than 17,000 people are seeking refuge in Texas shelters, the American Red Cross said. With rescues continuing, that number seemed certain to grow.

Calls for rescue have so overwhelmed emergency teams that they have had little time to search for bodies. And officials acknowledge that fatalities from Harvey could soar once the floodwaters start to recede from one of America’s most sprawling metropolitan centers.

More than four days after the storm ravaged the Texas coastline as a Category 4 hurricane, authorities had confirmed only three deaths — including a woman killed Monday when heavy rains dislodged a large oak tree onto her trailer home in the small town of Porter. But unconfirmed reports of others missing or presumed dead were growing.

“We know in these kinds of events that, sadly, the death toll goes up historically,” Houston Police Chief Art Acevedo told The Associated Press. “I’m really worried about how many bodies we’re going to find.”

One Houston woman said Monday that she presumes six members of a family, including four of her grandchildren, died after their van sank into Greens Bayou in East Houston.

Virginia Saldivar told The Associated Press her brother-in-law was driving the van Sunday when a strong current took the vehicle over a bridge and into the bayou. The driver was able to get out and urged the children to escape through the back door, Saldivar said, but they could not.

“I’m just hoping we find the bodies,” Saldivar said.

Houston emergency officials could not confirm the deaths.

A spokeswoman for a Houston hotel said one of its employees disappeared while helping about 100 guests and workers evacuate the building.

The disaster is unfolding on an epic scale, with the nation’s fourth-largest city mostly paralyzed by the storm that parked itself over the Gulf Coast. With nearly 2 more feet (61 centimeters) of rain expected on top of the 30-plus inches (76 centimeters) in some places, authorities worried the worst might be yet to come.

Early Tuesday, Harvey continued to drench Houston and the surrounding area. Rain fell at about half an inch (1 centimeter) per hour over Harris County — home to Houston — and up to 2 inches (5 centimeters) per hour to the east.

The Houston metro area covers about 10,000 square miles (25,900 square kilometers), an area slightly bigger than New Jersey. It’s crisscrossed by about 1,700 miles (2,700 kilometers) of channels, creeks and bayous that drain into the Gulf of Mexico, about 50 miles (80 kilometers) to the southeast from downtown.

President Donald Trump was expected Tuesday in Corpus Christi and Austin for briefings on the first major natural disaster of his administration. Vice President Mike Pence said in an interview with Corpus Christi radio station KKTX that he will visit southeast Texas later this week.

Forecasters expect the storm to linger over the Gulf before heading back inland east of Houston sometime Wednesday. The system will then head north and lose its tropical strength.

It could creep as far east as Mississippi by Thursday, meaning New Orleans, where Hurricane Katrina unleashed its full wrath in 2005, is in Harvey’s path. Foreboding images of Harvey were lighting up weather radar screens early Tuesday, the 12th anniversary of the day Katrina made landfall in Plaquemines Parish.

Rescuers meanwhile continued plucking people from inundated Houston neighborhoods. Mayor Sylvester Turner put the number by police at more than 3,000. The Coast Guard said it also had rescued more than 3,000 by boat and air and was taking more than 1,000 calls per hour.

Chris Thorn was among the many volunteers still helping with the mass evacuation that began Sunday. He drove with a buddy from the Dallas area with their flat-bottom hunting boat to pull strangers out of the water.

“I couldn’t sit at home and watch it on TV and do nothing since I have a boat and all the tools to help,” he said.

Nearly 6,000 inmates displaced by flooding have been moved from prisons in the Houston area to other facilities in South and East Texas, according to the state Department of Criminal Justice.

A mandatory evacuation was ordered for the low-lying Houston suburb of Dickinson, home to 20,000. Police cited the city’s fragile infrastructure in the floods, limited working utilities and concern about the weather forecast.

In Houston, questions continued to swirl about why the mayor did not issue a similar evacuation order.

Turner has repeatedly defended the decision and did so again Monday, insisting that a mass evacuation of millions of people by car was a greater risk than enduring the storm.

“Both the county judge and I sat down together and decided that we were not in direct path of the storm, of the hurricane, and the safest thing to do was for people to stay put, make the necessary preparations. I have no doubt that the decision we made was the right decision.”

He added, “Can you imagine if millions of people had left the city of Houston and then tried to come back in right now?”

By Tuesday morning, more than 9,000 people were at the city’s largest shelter set up inside the George R. Brown Convention Center — which originally had an estimated capacity of 5,000.

Red Cross spokesman Lloyd Ziel said that volunteers made more space inside the center, which also was used to house Hurricane Katrina refugees from New Orleans in 2005, in part by pushing some cots closer together. A shortage of cots means some people will have to sleep on chairs or the floor.

The center settled down at night, after an occasionally chaotic day that saw thousands of evacuees arrive in the pouring rain. Officers and volunteers at times rushed to attend to those with medical needs.

Before the storm is gone, up to 20 more inches (51 centimeters) of rain could fall, National Weather Service Director Louis Uccellini said Monday.

That means the flooding will get worse in the days ahead and the floodwaters will be slow to recede once Harvey finally moves on, the weather service said.

Sometime Tuesday or early Wednesday, parts of the Houston region will probably break the nearly 40-year-old U.S. record for the biggest rainfall from a tropical system — 48 inches (120 centimeters) — set by Tropical Storm Amelia in 1978 in Texas, meteorologists said.

Associated Press writers Juan Lozano and Nomaan Merchant in Houston and David Warren in Dallas contributed to this report. </s> Tropical Storm Harvey bore down on Louisiana on Wednesday, pouring down more water after setting rainfall records in Texas that caused catastrophic flooding and paralyzed the U.S. energy hub of Houston.

The storm that first came ashore on Friday as the most powerful hurricane to hit Texas in more than 50 years has killed at least 17 people and forced tens of thousands to leave their deluged homes.

Damage has been estimated at tens of billions of dollars, making it one of the costliest U.S. natural disasters.

Opinion: Why the U.S. wasn't prepared for Hurricane Harvey

There is some relief in sight for Houston, the fourth most populous U.S. city, with forecasters saying five days of torrential rain may come to an end as the storm picks up speed and leaves the Gulf of Mexico region later in the day.

Harvey made landfall early Wednesday and was about 32 miles (52 km) south of Lake Charles, Louisiana. It was expected to bring an additional 3 to 6 inches (7.5 to 15.24 cms) of rain to an area about 80 miles east of Houston as well as southwestern Louisiana, where some areas have already seen more than 18 inches of rain.

Several hundred people had already been rescued from their homes in Lake Charles, Louisiana, where floodwaters were knee-deep in places, Mayor Nic Hunter told CNN.

"We are a very resilient people down here. We will survive. We will take care of each other down here in Texas and Louisiana," Hunter said. "But we do need some help from the federal government, these homeowners and these people who have been displaced. That's going to be our biggest need."

Harvey is projected to weaken as it moves inland to the northeast, the National Hurricane Center said.

"We aren't going to be dealing with it for too much longer. It's going to pick up the pace and get out of here," said Donald Jones, a meteorologist at the National Weather Service in Lake Charles.

But nearly a third of Harris County, home to Houston, was under water, an area 15 times the size of Manhattan, according to the Houston Chronicle newspaper. It may take days for all flood waters, which have spilled over dams and pushed levees to their limits, to recede, local officials said.

City officials were preparing to temporarily house some 19,000 people, with thousands more expected to flee. As of Wednesday morning, state officials said close to 49,000 homes had suffered flood damage, with more than 1,000 destroyed.

Houston Mayor Sylvester Turner imposed a curfew from 12 a.m. to 5 a.m. amid reports of looting, armed robberies and people impersonating police officers.

U.S. President Donald Trump visited Texas on Tuesday to survey damage from the first major natural disaster to test his crisis leadership. The president said he was pleased with the response, but too soon for a victory lap.

"We won't say congratulations," he said. "We don't want to do that ... We'll congratulate each other when it's all finished."

Moody's Analytics is estimating the economic cost from Harvey for southeast Texas at $51 billion to $75 billion.

The storm has affected nearly one-fifth of U.S. refining capacity, sparking concerns about gasoline supply. The national average gasoline price rose to $2.404 a gallon, up six cents from a week ago, with higher spikes in Texas.

The unprecedented flooding has left scores of neighborhoods in chest-deep water and badly strained the dams and drainage systems that protect the low-lying Houston metropolitan area whose economy is about as large as Argentina's.

The National Weather Service has issued flood watches and warnings that stretch from the Houston area into Tennessee.

Harvey has drawn comparisons with Hurricane Katrina, which devastated New Orleans 12 years ago, killing more than 1,800 people and causing an estimated $108 billion in damage.

Among the confirmed fatalities was Houston Police Sergeant Steve Perez, a 34-year veteran of the force who drowned while attempting to drive to work on Sunday.

In Beaumont, northeast of Houston, a woman clutching her baby daughter was swept away in raging flooding. The baby was saved but the mother died, Beaumont police said.

Ruben Jordan, a retired high school football coach died when he was helping rescue people trapped in high water, the Clear Creek Independent School District said.

In all, 17 people have perished, according to government officials and the Houston Chronicle. Four volunteer rescuers also went missing after their boat was swept in a fast-moving current, local media reported.

U.S. Coast Guard helicopters and boats have rescued more than 4,000 people. Thousands of others have been taken to safety by police, rescue workers and citizen volunteers who brought their boats to help, local officials said.

The National Hurricane Center on Tuesday afternoon said a record 51.88 inches (131.78 cm) of rain had fallen in Texas due to Harvey, a record for any storm in the continental United States.

This breaks the previous record of 48 inches set during tropical storm Amelia in 1978 in Medina, Texas, the NHC said. Medina is west of San Antonio. The island of Kauai was hit with 52 inches of rain from tropical cyclone Hiki in 1950, before Hawaii became a U.S. state. </s> Tropical Storm Harvey continued to deluge southeast Texas with rain and surging floodwater Tuesday, breaking the record for the most extreme rainfall on the U.S. mainland.

Since Harvey made landfall Friday night as a hurricane, some areas of Houston have seen up to 50 inches of rain — more than they usually receive in a year.

On Tuesday afternoon, the Mont Belvieu industrial suburb east of Houston recorded 51.12 inches of water, breaking the highest previous record of 48 inches from 1978's tropical storm Amelia in Medina, Texas.

"It's the heaviest storm on record anywhere in the U.S. outside Hawaii," said John Nielsen-Gammon, Texas state climatologist and professor at Texas A&M University. "And it's still raining."

With muddy brown water engulfing huge swaths of the nation's fourth-largest city and much of the Gulf Coast, at least 10 people are dead and thousands are in shelters.

Federal officials have estimated as many as 30,000 displaced residents may seek temporary shelter and more than 450,000 people likely are to seek federal aid.

"In four days, we've seen a trillion gallons of water in Harris County — enough water to run Niagara Falls for 15 days," said Jeff Lindner, a meteorologist with the Harris County Flood Control District, who estimated as many as 100,000 homes in the 1,777-square-mile area had flooded. "It's beyond anything we've ever seen and will probably ever see."

As a light rain continued to drizzle, a reservoir west of downtown Houston spilled over for the first time in its history, leaving yet more residents desperately scrambling to safety.

In a Tuesday morning press briefing, Police Chief Art Acevedo said officers had rescued 3,500 people across the city and were launching more boats in the water every hour. They also arrested a crew of armed robbers who were hijacking vehicles.

"We're still trying to get to folks," Acevedo said. "Don't give up on us. Seek the higher ground. We will get to you."

Overnight, the number of people sheltering at the George R. Brown convention center swelled to 9,000 people. Its capacity is supposed to be 5,000. Mayor Sylvester Turner said the city asked the Federal Emergency Management Agency for cots and food for an additional 10,000 people, and officials are planning to open other mega shelters.

"We are not turning anyone away," Turner said.

Houston highways remained mostly empty and blocked by police early Tuesday. A few cars and trucks navigated wet streets downtown.

Families still were arriving at the massive convention center, some with sleeping pads and rain boots, others with their belongings in garbage bags. Some feared for relatives left behind, and others worried they might soon face shortages of food and other supplies.

By Tuesday, the death toll had risen to at least 10 after a man in Montgomery County, north of Houston, drowned Monday night while trying to swim across a flooded road.

Officials in Harris County, which includes Houston, have reported at least six "potentially storm-related" fatalities. A 60-year-old woman died Monday in Porter, a small community north of Houston, when a large oak tree fell on her mobile home. Another person died in the small coastal town of Rockport, near where Harvey made landfall. A 52-year-old homeless man was found dead in La Marque, a small city near Galveston.

Early Tuesday, a major dam outside Houston began to overflow, threatening some of the hardest-hit neighborhoods to the west of the city. Engineers had tried to prevent Addicks Reservoir from overspilling by releasing some of its water Monday, but flood control officials reported Tuesday morning that water was beginning to seep over the top of a spillway, the first time water had breached the dam.

In some areas, the water in the Houston area was so deep that rain sensors no longer were working. The Harris County Flood Control District, a government agency that works to reduce the effects of flooding in the area that includes Houston, announced multiple water level and rain sensors were out of service due to flooding.

In Brazoria County, south of Houston, the Brazos River was beginning to overflow its banks. On Tuesday morning, a levee breached in the Columbia Lakes neighborhood.

"We are asking residents to please get out," said Sharon Trower, a spokeswoman for the county, which already has rescued hundreds of residents after severe flooding from heavy rainfall. "The additional river flooding is just going to be catastrophic."

Major roads throughout the county already were closed because of flooding.

While catastrophic flooding continues across southeast Texas, flash flood watches dropped for western portions of the Houston area as light to moderate rain fell Monday night. The National Weather Service said the threat of flooding is gradually shifting east.

"Expect improving conditions this afternoon and evening across the area as Harvey pushes northeast," the National Weather Service's Houston/Galveston office said in an update.

After assuring Texas on Monday that Congress would deliver swift federal aid, President Donald Trump visited the storm-ravaged state Tuesday.

As Harvey moved closer to neighboring Louisiana on the 12th anniversary of Hurricane Katrina, New Orleans Mayor Mitch Landrieu urged residents to stay home and shelter in place.

A few inches of rain could cause serious problems in New Orleans, which still is recovering from flooding after thunderstorms this month overwhelmed the city's drainage system.

More than 5 inches of rain fell in some parts of the city Monday, causing localized floods. Flash flood watches were in effect as meteorologists forecast 4 more inches of rain Tuesday.

"Today, we are a resilient city with greater resolve, but we remain vigilant in the face of another threatening storm," Landrieu said in a statement. "While this is a somber day for New Orleanians, the determination and spirit of our people gives us great hope for the future." </s> Floodwaters reached the rooflines of single-story homes Monday and people could be heard pleading for help from inside as Harvey poured rain on the Houston area for a fourth consecutive day after a chaotic weekend of rising water and rescues.

The nation's fourth-largest city was still mostly paralyzed by one of the largest downpours in U.S. history. And there was no relief in sight from the storm that spun into Texas as a Category 4 hurricane, then parked over the Gulf Coast. With nearly 2 more feet of rain expected on top of the 30-plus inches in some places, authorities worry the worst might be yet to come.

Harvey has been blamed for at least three confirmed deaths, including a woman killed Monday in the town of Porter, northeast of Houston, when a large oak tree dislodged by heavy rains toppled onto her trailer home.

A Houston television station reported Monday that six family members were believed to have drowned when their van was swept away by floodwaters. The KHOU report was attributed to three family members the station did not identify. No bodies have been recovered.

Police Chief Art Acevedo told The Associated Press he had no information about the report but said he's "really worried about how many bodies we're going to find."

According to the station, four children and their grandparents were feared dead after the van hit high water Sunday when crossing a bridge in the Greens Bayou area.

The driver of the vehicle, the children's great-uncle, reportedly escaped before the van sank by grabbing a tree limb. He told the children to try to escape through the back door, but they were unable to get out.

The disaster unfolded on an epic scale in one of America's most sprawling metropolitan centers. The Houston metro area covers about 10,000 square miles, an area slightly bigger than New Jersey. It's crisscrossed by about 1,700 miles of channels, creeks and bayous that drain into the Gulf of Mexico, about 50 miles to the southeast from downtown.

The storm is generating an amount of rain that would normally be seen only once in more than 1,000 years, said Edmond Russo, a deputy district engineer for the Army Corps of Engineers, which was concerned that floodwater would spill around a pair of 70-year-old reservoir dams that protect downtown Houston.

The flooding was so widespread that the levels of city waterways have equaled or surpassed those of Tropical Storm Allison from 2001, and no major highway has been spared some overflow.

The city's normally bustling business district was virtually deserted Monday, with emergency vehicles making up most of the traffic.

Rescuers continued plucking people from the floodwaters. Mayor Sylvester Turner put the number rescued by police at more than 3,000. The Coast Guard said it also rescued more than 3,000 by boat and air and was taking more than 1,000 calls per hour.

Chris Thorn was among the many volunteers still helping with the mass evacuation that began Sunday. He drove with a buddy from the Dallas area with their flat-bottom hunting boat to pull strangers out of the water.

"I couldn't sit at home and watch it on TV and do nothing since I have a boat and all the tools to help," he said.

They got to Spring, Texas, where Cypress Creek had breached Interstate 45 and went to work, helping people out of a gated community near the creek.

"It's never flooded here," Lane Cross said from the front of Thorn's boat, holding his brown dog, Max. "I don't even have flood insurance."

A mandatory evacuation was ordered for the low-lying Houston suburb of Dickinson, home to 20,000. Police cited the city's fragile infrastructure in the floods, limited working utilities and concern about the weather forecast.

In Houston, questions continued to swirl about why the mayor did not issue a similar evacuation order.

Turner has repeatedly defended the decision and did so again Monday, insisting a mass evacuation of millions of people by car was a greater risk than enduring the storm.

"Both the county judge and I sat down together and decided that we were not in direct path of the storm, of the hurricane, and the safest thing to do was for people to stay put, make the necessary preparations. I have no doubt that the decision we made was the right decision."

He added, "Can you imagine if millions of people had left the city of Houston and then tried to come back in right now?"

The Red Cross quickly set up the George R. Brown Convention Center and other venues as shelters. The center, which was also used to house Hurricane Katrina refugees from New Orleans in 2005, can accommodate roughly 5,000 people. By Monday evening, it was nearly full.

At the Addicks and Barker reservoirs, the Army Corps started releasing water Monday because water levels were climbing at a rate of more than 6 inches per hour, Corps spokesman Jay Townsend said.

The move was supposed to help shield the business district from floodwaters, but it also risked flooding thousands more homes in nearby subdivisions. Built after devastating floods in 1929 and 1935, the reservoirs were designed to hold water until it can be released downstream at a controlled rate.

In the Cypress Forest Estates neighborhood in northern Harris County, people called for help from inside homes as water from a nearby creek rose to their eaves. A steady procession of rescue boats floated into the area.

Harvey increased slightly in strength Monday as it drifted back over the warm Gulf, according to the National Hurricane Center.

Forecasters expect the system to stay over water with 45 mph (72 kph) winds for 36 hours and then head back inland east of Houston sometime Wednesday. The system will then head north and lose its tropical strength.

Before then, up to 20 more inches of rain could fall, National Weather Service Director Louis Uccellini said Monday.

That means the flooding will get worse in the days ahead and the floodwaters will be slow to recede once Harvey finally moves on, the weather service said.

Sometime Tuesday or early Wednesday, parts of the Houston region will probably break the nearly 40-year-old U.S. record for the biggest rainfall from a tropical system — 48 inches, set by Tropical Storm Amelia in 1978 in Texas, meteorologists said.

The amount of water in Houston was so unprecedented that the weather service on Wednesday had to update the color charts on its official rainfall maps to indicate the heavier totals.

In Louisiana, the images of the devastation in Houston stirred up painful memories for many Hurricane Katrina survivors.

"It really evoked a lot of emotions and heartbreak for the people who are going through that now in Houston," Ray Gratia said as he picked up sandbags for his New Orleans home, which flooded during the 2005 hurricane.

In Washington, President Donald Trump's administration assured Congress that the $3 billion balance in the Federal Emergency Management Agency's disaster fund was enough to handle immediate needs, such as debris removal and temporary shelter for displaced residents. Trump plans to visit Texas today.

Harvey was the fiercest hurricane to hit the U.S. in 13 years and the strongest to strike Texas since 1961's Hurricane Carla, the most powerful Texas hurricane on record. </s> HOUSTON — Harvey’s floodwaters started dropping across much of the Houston area and the sun came out Wednesday in a glimmer of hope for the stricken city, even as the storm doubled back toward land and pounded communities farther east, near the Texas-Louisiana line.

The scope of the devastation caused by the hurricane came into sharper focus, meanwhile, and the murky green floodwaters from the record-breaking, 4-foot deluge of rain began yielding up bodies as predicted.

The confirmed death toll climbed to 23, including six family members — four of them children — whose bodies were pulled Wednesday from a van that had been swept off a Houston bridge into a bayou.

Authorities are investigating at least 17 more deaths to determine whether they were storm-related.

“Unfortunately, it seems that our worst thoughts are being realized,” Harris County Sheriff Ed Gonzalez said after the van that disappeared over the weekend was found in 10 feet of muddy water.

 While conditions in the nation’s fourth-largest city appeared to improve, authorities warned that the crisis in Houston and across the region is far from over. The storm, in fact, took a turn for the worse east of the city, close to the Louisiana line.

Beaumont and Port Arthur, Texas, struggled with rising floodwaters and worked to evacuate residents after Harvey completed a U-turn in the Gulf of Mexico and rolled ashore early Wednesday for the second time in six days. It hit southwestern Louisiana as a tropical storm with heavy rain and winds of 45 mph.

Forecasters predicted that a wobbling and weakening Harvey would be downgraded to a tropical depression late Wednesday or early Thursday and completely dissipate within three to four days.

 But it still has lots of rain and potential damage to spread, with 4 to 8 inches forecast from the Louisiana-Texas line into Tennessee and Kentucky through Friday. Some spots may get as much as a foot, raising the risk of more flooding.

For much of the Houston area, forecasters said the rain is pretty much over.

“We have good news,” said Jeff Lindner, a meteorologist with the Harris County Flood Control District. “The water levels are going down.”

Houston Mayor Sylvester Turner said the city’s two major airports would be up and running again in the afternoon.

At Hermann Park, south of downtown, children glided by in strollers and wagons, joggers took in midday runs and couples walked beside cascading fountains and beneath a sparkling sun. People pulled into drive-thru restaurants and emerged from a store with groceries.

At the same time, many thousands of Houston-area homes are under water and could stay that way for days or weeks. And Lindner cautioned that homes near at least one swollen bayou could still get flooded.

Officials said 911 centers in the Houston area are getting more than 1,000 calls an hour from people seeking help.

In Houston’s flooded Meyerland neighborhood, hundreds of families emptied their homes of sodden possessions under a baking sun as the temperature climbed into the 90s. They piled up couches, soggy drywall and carpets ripped out of foul-smelling homes where the floodwaters had lingered for more than 24 hours.

The curbs were lined with the pickup trucks of cleanup contractors and friends.

For Harry Duffey, a 48-year-old computer security specialist, this was flood No. 3 in as many years. Just before the flood, he got a notice that his flood insurance premium had nearly doubled to $5,300 a year.

“Everywhere we look this water has cost me money after money after money. It just does not end,” he said. But he said he has no intention of moving: “This is in my blood. This is where I’m from.”

Altogether, more than 1,000 homes in Texas were destroyed and close to 50,000 damaged, and over 32,000 people were in shelters across the state, emergency officials reported. About 10,000 more National Guard troops are being deployed to Texas, bringing the total to 24,000, Gov. Greg Abbott said.

“This is going to be an incredibly large disaster,” Brock Long, chief of the Federal Emergency Management Agency, said in Washington. “We’re not going to know the true cost for years to come. … But it’s going to be huge.”

Confirmed deaths from the storm include a married couple who drowned after their pickup truck was swept away while they were on the phone with a 911 dispatcher asking for help, officials said.

Others among the dead include a woman whose body was discovered floating in Beaumont, a man who tried to swim across a flooded road, and a woman who died after she and her young daughter were swept into a drainage canal in Beaumont. The child was rescued clinging to her dead mother, authorities said.

When Harvey paid its return visit to land overnight, it hit near Cameron, Louisiana, about 45 miles from Port Arthur.

Port Arthur found itself increasingly isolated as floodwaters swamped most major roads out of the city and spilled into a storm shelter with about 100 people inside. Motiva Enterprises closed its Port Arthur refinery, the largest in the nation, because of flooding.

Port Arthur Mayor Derrick Freeman posted on his Facebook page: “city is underwater right now but we are coming!” He urged residents to move to higher ground and avoid getting trapped in attics.

 More than 500 people — along with dozens of dogs, cats, a lizard and a monkey — took shelter at the Max Bowl bowling alley in Port Arthur after firefighters popped the lock in the middle of the night, said the establishment’s general manager, Jeff Tolliver.

“The monkey was a little surprising, but we’re trying to help,” he said.

In Orange, Texas, about 30 miles east of Beaumont, residents of a retirement home surrounded by thigh-deep water were rescued by National Guardsmen and wildlife officers, who carried them from the second floor and put them aboard an airboat.

Harvey initially came ashore as a Category 4 hurricane in Texas on Friday, then went back out to sea and lingered off the coast as a tropical storm for days, inundating flood-prone Houston.

 Harvey’s five straight days of rain totaled close to 52 inches, the heaviest tropical downpour ever recorded in the continental U.S.

The death toll from Hurricane Harvey in the American city of Houston, Texas, rises to three with several more days of heavy rain causing "catastrophic" floods to come.
