Atlantic hurricane season - wikipedia Atlantic hurricane season For the active season, see 2017 Atlantic hurricane season. Tracks of all known Atlantic tropical cyclones from 1851 to 2012. A whiteboard at a FEMA tactical relief operation center in Louisiana notes the number of named storms and hurricanes and counts down the days remaining in the 2008 Atlantic hurricane season. Play media Hurricane tracks from 1980 through 2014. Green tracks did not make landfall in US ; yellow tracks made landfall but were not major hurricanes at the time ; red tracks made landfall and were major hurricanes. The Atlantic hurricane season is the period in a year when hurricanes usually form in the Atlantic Ocean. Tropical cyclones in the North Atlantic are called hurricanes, tropical storms, or tropical depressions. In addition, there have been several storms over the years that have not been fully tropical and are categorized as subtropical depressions and subtropical storms. Even though subtropical storms and subtropical depressions are not technically as strong as tropical cyclones, the damages can still be devastating. Worldwide, tropical cyclone activity peaks in late summer, when the difference between temperatures aloft and sea surface temperatures is the greatest. However, each particular basin has its own seasonal patterns. On a worldwide scale, May is the least active month, while September is the most active. In the Northern Atlantic Ocean, a distinct hurricane season occurs from June 1 to November 30, sharply peaking from late August through September ; the season 's climatological peak of activity occurs around September 10 each season. This is the norm, but in 1938, the Atlantic hurricane season started as early as January 3. Tropical disturbances that reach tropical storm intensity are named from a pre-determined list. On average, 10.1 named storms occur each season, with an average of 5.9 becoming hurricanes and 2.5 becoming major hurricanes ( Category 3 or greater ). The most active season was 2005, during which 28 tropical cyclones formed, of which a record 15 became hurricanes. The least active season was 1914, with only one known tropical cyclone developing during that year. The Atlantic hurricane season is a time when most tropical cyclones are expected to develop across the northern Atlantic Ocean. It is currently defined as the time frame from June 1 through November 30, though in the past the season was defined as a shorter time frame. During the season, regular tropical weather outlooks are issued by the National Hurricane Center, and coordination between the Weather Prediction Center and National Hurricane Center occurs for systems which have not formed yet, but could develop during the next three to seven days.

It was originally the time frame when the tropics were monitored routinely for tropical cyclone activity, and was originally defined as from June 15 through October 31. Over the years, the beginning date was shifted back to June 1, while the end date was shifted to November 15, before settling at November 30 by 1965. This was when hurricane reconnaissance planes were sent out to fly across the Atlantic and Gulf of Mexico on a routine basis to look for potential tropical cyclones, in the years before the continuous weather satellite era. Since regular satellite surveillance began, hurricane hunter aircraft fly only into storm areas which are first spotted by satellite imagery. Operations See also : National Hurricane Center and Weather Prediction Center During the hurricane season, the National Hurricane Center routinely issues their Tropical Weather Outlook product, which identifies areas of concern within the tropics which could develop into tropical cyclones. If systems occur outside the defined hurricane season, special Tropical Weather Outlooks will be issued. Routine coordination occurs at 1700 UTC each day between the Weather Prediction Center and National Hurricane Center to identify systems for the pressure maps three to seven days into the future within the tropics, and points for existing tropical cyclones six to seven days into the future. Possible tropical cyclones are depicted with a closed isobar, while systems with less certainty to develop are depicted as `` spot lows '' with no isobar surrounding them. HURDAT Main article : HURDAT The North Atlantic hurricane database, or HURDAT, is the database for all tropical storms and hurricanes for the Atlantic Ocean, Gulf of Mexico and Caribbean Sea, including those that have made landfall in the United States. The original database of six - hourly positions and intensities were put together in the 1960s in support of the Apollo space program to help provide statistical track forecast guidance. In the intervening years, this database -- which is now freely and easily accessible on the Internet from the National Hurricane Center 's ( NHC ) webpage -- has been utilized for a wide variety of uses : climatic change studies, seasonal forecasting, risk assessment for county emergency managers, analysis of potential losses for insurance and business interests, intensity forecasting techniques and verification of official and various model predictions of track and intensity. HURDAT was not designed with all of these uses in mind when it was first put together and not all of them may be appropriate given its original motivation. HURDAT contains numerous systematic as well as some random errors in the database. Additionally, analysis techniques have changed over the years at NHC as their understanding of tropical cyclones has developed, leading to biases in the historical database. Another difficulty in applying the hurricane database to studies concerned with landfalling events is the lack of exact location, time and intensity at hurricane landfall. Re-analysis project Main article : Atlantic hurricane reanalysis HURDAT is regularly updated annually to reflect the previous season 's activity. The older portion of the database has been regularly revised since 2001. The first time in 2001 led to the addition of tropical cyclone tracks for the years 1851 to 1885. The second time was August 2002 when Hurricane Andrew was upgraded to a Category 5. Recent efforts into uncovering undocumented historical hurricanes in the late 19th and 20th centuries by various researchers have greatly increased our knowledge of these past events. Possible changes for the years 1951 onward are not yet incorporated into the HURDAT database. Because of all of these issues, a re-analysis of the Atlantic hurricane database is being attempted that will be completed in three years. In addition to the groundbreaking work by Partagas, additional analyses, digitization and quality control of the data was carried out by researchers at the NOAA Hurricane Research Division funded by the NOAA Office of Global Programs. This re-analysis will continue to progress through the remainder of the 20th century. The National Hurricane Center 's Best Track Change Committee has approved changes for a few recent cyclones, such as Hurricane Andrew. Official changes to the Atlantic hurricane database are approved by the National Hurricane Center Best Track Change Committee. Thus research conducted by Chris Landsea and colleagues as part of the Atlantic hurricane database reanalysis project are submitted through this review process. Not all Landsea 's recommendations are accepted by the Committee. 1494 - 1850 ( pre-HURDAT era ) Period Seasons Individual years Pre-19th century Pre-17th century ( pre 1600 ), 17th century ( 1600s ), 18th century ( 1700s ) 1780 1800 -- 1849 1800 -- 1809, 1810 -- 1819, 1820 -- 1829, 1830 -- 1839, 1840 -- 1849 1842 1850 - 1899 ( 1851 - present HURDAT era ) 1850s Year Number of tropical storms Number of hurricanes Number of major hurricanes Deaths Strongest storm Major landfall hurricanes Notes 1850 0 0 Not known One 1851 6 24 Four Great Middle Florida Hurricane of 1851 ( cat 3 ) 1852 5 5 100 + One Great Mobile Hurricane of 1852 ( cat 3 ) 1853 8 40 Three 1854 5 30 + Three Coastal Hurricane of 1854 ( cat 3 ) 1855 5 Not known Five Middle Gulf Shore Hurricane of 1855 ( cat 3 ) 1856 6 200 + One The Last Island Hurricane of 1856 ( cat 4 ) 1857 0 424 Two & Four 1858 6 6 0 None Three & Six 1859 8 7 Numerous Six 1860s Year Number of tropical storms Number of hurricanes Number of major hurricanes Deaths Strongest storm Major landfall hurricanes Notes 1860 7 6 60 + One 1861 6 0 22 + One and Three 1862 0 Two and Three 1863 5 0 90 One, Two, Three & Four 1864 0 None One, Three & Five 1865 0 326 Four & Seven 1866 7 6 383 Six Great Bahamas Hurricane of 1866 ( cat 4 ) 1867 6 811 ' San Narciso ' Hurricane San Narciso of 1867 ( cat 3 ) 1868 0 One, Two & Four 1869 6 38 Six New England Gale of 1869 ( cat 3 ) 1870s Year Number of tropical storms Number of hurricanes Number of major hurricanes Deaths Strongest storm Major landfall hurricanes Notes 1870 11 10 2,052 Four Hurricane of San Marcos of 1870 ( cat 3 ) 1871 8 6 30 Three and Four Central Florida Hurricane of 1871 ( cat 3 ) Hurricane Santa Juana of 1871 ( cat 3 ) 1872 5 0 Unknown Two 1873 5 626 Five Central Florida Hurricane of 1873 ( cat 3 ) 1874 7 0 Unknown Seven 1875 6 5 800 Three Great Indianola Hurricane of 1875 ( cat 3 ) 1876 5 19 `` San Felipe '' Hurricane San Felipe of 1876 ( cat 3 ) Cuba - South Florida Hurricane of 1876 ( cat 3 ) 1877 8 34 Four 1878 12 10 108 Seven 1879 8 6 47 Four Great Beaufort Carolina Hurricane of 1879 ( cat 3 ) Louisiana Hurricane of 1879 ( cat 3 ) 1880s Year Number of tropical storms Number of hurricanes Number of major hurricanes Deaths Strongest storm Major landfall hurricanes Notes 1880 11 9 133 Eight Brownsville Hurricane of 1880 ( cat 4 ) 1881 7 0 700 Five and Six Georgia Hurricane of 1881 ( cat 2 ) 700 + dead 1882 6 5 6 Six Pensacola Hurricane of 1882 ( cat 3 ) Cuba Hurricane of 1882 ( cat 4 ) 1883 236 Two and Three Bahamas - North Carolina Hurricane of 1883 ( cat 3 ) 1884 8 Two 1885 8 6 25 Two 1886 12 10 200 + `` Indianola '' Indianola Hurricane of 1886 ( cat 4 ) Cuba Hurricane of 1886 ( cat 3 ) Texas - Louisiana Hurricane of 1886 ( cat 3 ) Seven hurricanes struck the United States, the most during a single year.

Only one of four seasons to produce ten hurricanes in a row, ( 1878, 1886, 1893 and 2017 ) Only season to produce ten consecutive hurricanes in the modern satellite era. Only season on record with three hurricanes with an ACE value over 40, Irma, Jose, and Maria Most ACE produced in a single month in Atlantic basin ( September ) Fastest moving tropical cyclone ever recorded in Gulf of Mexico, Nate Number of tropical storms and hurricanes per season See also : Tropical cyclones and climate change This bar chart shows the number of named storms and hurricanes per year from 1851 - 2017. A 2011 study analyzing one of the main sources of hurricanes - the African easterly wave ( AEW ) - found that the change in AEWs is closely linked to increased activity of intense hurricanes in the North Atlantic. The synoptic concurrence of AEWs in driving the dynamics of the Sahel greening also appears to increase tropical cyclogenesis over the North Atlantic.
