You can help by expanding it with reliably sourced entries. Since the reliable record keeping of tropical cyclone data within the North Atlantic Ocean began in 1851, there have been 1,505 systems of at least tropical storm intensity and 879 of at least hurricane intensity. Though a majority of these tropical depressions have fallen within climatological averages, prevailing atmospheric conditions occasionally lead to anomalous tropical systems which at times reach extremes in statistical record - keeping including in duration and intensity. The scope of this list is limited to tropical cyclone records solely within the Atlantic Ocean and is subdivided by their reason for notability.

Climatologically speaking, approximately 97 percent of tropical cyclones that form in the North Atlantic develop between the dates of June 1 and November 30 -- dates which delimit the modern - day Atlantic hurricane season. Though the beginning of the annual hurricane season has historically remained the same, the official end of the hurricane season has shifted from its initial date of October 31. Regardless, on average once every few years a tropical cyclone develops outside the limits of the season ; as of November 2017 there have been 68 tropical cyclones in the off - season, with the most recent being Tropical Storm Arlene in 2017. The first tropical cyclone of the 1938 Atlantic hurricane season, which formed on January 3, became the earliest forming tropical storm and hurricane after reanalysis concluded on the storm in December 2012. Hurricane Able in 1951 was initially thought to be the earliest forming major hurricane -- a tropical cyclone with winds exceeding 115 mph ( 185 km / h ) -- however following post-storm analysis it was determined that Able only reached Category 1 strength which made Hurricane Alma of 1966 the new record holder ; as it became a major hurricane on June 8. Though it developed within the bounds of the Atlantic hurricane season, Hurricane Audrey in 1957 was the earliest developing Category 4 hurricane on record after it reached the intensity on June 27. However, reanalysis from 1956 to 1960 by NOAA downgraded Audrey to a Category 3, making Hurricane Dennis of 2005 the earliest Category 4 on record on July 8, 2005. The earliest - forming Category 5 hurricane, Emily, reached the highest intensity on the Saffir -- Simpson hurricane wind scale on July 17, 2005. Though the official end of the Atlantic hurricane season occurs on November 30, the dates of October 31 and November 15 have also historically marked the official end date for the hurricane season. December, the only month of the year after the hurricane season, has featured the cyclogenesis of fourteen tropical cyclones. Tropical Storm Zeta in 2005 was the latest tropical cyclone to attain tropical storm intensity as it did so on December 30. However, the second Hurricane Alice in 1954 was the latest forming tropical cyclone to attain hurricane intensity. Both Alice and Zeta were the only two storms to exist in two calendar years -- the former from 1954 to 1955 and the latter from 2005 to 2006. No storms have been recorded to exceed Category 1 hurricane intensity in December. In 1999, Hurricane Lenny reached Category 4 intensity on November 17 as it took an unprecedented west to east track across the Caribbean ; its intensity made it the latest developing Category 4 hurricane, though this was well within the bounds of the hurricane season. Hurricane Hattie ( October 27 - November 1, 1961 ) was initially thought to have been the latest forming Category 5 hurricane ever documented, though reanalysis indicated that a devastating hurricane in 1932 reached such an intensity at a later date. Consequently, this made the hurricane the latest developing tropical cyclone to reach all four Saffir -- Simpson hurricane wind scale classifications past Category 1 intensity.

The following table lists the most intense Atlantic hurricanes in terms of their lowest barometric pressure. In terms of wind speed, Allen from 1980 was the strongest Atlantic tropical cyclone on record, with maximum sustained winds of 190 mph ( 310 km / h ). For many years, it was thought that Hurricane Camille also attained this intensity, but this conclusion was changed in 2014. The original measurements of Camille are suspect since wind speed instrumentation used at the time would likely be damaged by winds of such intensity. Nonetheless, their central pressures are low enough to rank them among the strongest recorded Atlantic hurricanes. Owing to their intensity, the strongest Atlantic hurricanes have all attained Category 5 classification. Hurricane Opal, the strongest Category 4 hurricane recorded, intensified to reach a minimum pressure of 916 mbar ( hPa ; 27.05 inHg ), a pressure typical of Category 5 hurricanes. Nonetheless, the pressure remains too high to list Opal as one of the ten strongest Atlantic tropical cyclones. Presently, Hurricane Wilma is the strongest Atlantic hurricane ever recorded, after reaching an intensity of 882 mbar ( hPa ; 26.05 inHg ) in October 2005 ; this also made Wilma the strongest tropical cyclone worldwide outside of the West Pacific, where seven tropical cyclones have been recorded to intensify to lower pressures. However, this was later superseded by Hurricane Patricia in 2015 in the east Pacific, which had a pressure reading of 872 mbar. Preceding Wilma is Hurricane Gilbert, which had also held the record for most intense Atlantic hurricane for 17 years. The 1935 Labor Day hurricane, with a pressure of 892 mbar ( hPa ; 26.34 inHg ), is the third strongest Atlantic hurricane and the strongest documented tropical cyclone prior to 1950. Since the measurements taken during Wilma and Gilbert were documented using dropsonde, this pressure remains the lowest measured over land. Hurricane Rita is the fourth strongest Atlantic hurricane in terms of barometric pressure and one of three tropical cyclones from 2005 on the list, with the others being Wilma and Katrina at first and seventh, respectively. However, with a barometric pressure of 895 mbar ( hPa ; 26.43 inHg ), Rita is the strongest tropical cyclone ever recorded in the Gulf of Mexico.

Allen 's pressure was measured at 899 mbar. Hurricane Camille is the sixth strongest hurricane on record. Camille is the only storm to have been moved down the list due to post-storm analysis. Camille was originally recognized as the fifth strongest hurricane on record, but was dropped to the seventh strongest in 2014, with an estimated pressure at 905 mbars, tying it with Hurricanes Mitch, and Dean. Camille then was recategorized with a new pressure of 900 mbars. Currently, Mitch and Dean share intensities for the eighth strongest Atlantic hurricane at 905 mbar ( hPa ; 26.73 inHg ). Hurricane Maria is in tenth place for most intense Atlantic tropical cyclone, with a pressure as low as 908 mbar ( hPa ; 26.81 inHg ). In addition, the most intense Atlantic hurricane outside of the Caribbean Sea and Gulf of Mexico is Hurricane Irma of 2017, with a pressure of 914 mbar ( hPa ; 27.0 inHg ). Many of the strongest recorded tropical cyclones weakened prior to their eventual landfall or demise. However, six of the storms remained intense enough at landfall to be considered some of the strongest landfalling hurricanes -- six of the ten hurricanes on the list constitute six of the most intense Atlantic landfalls in recorded history. The 1935 Labor Day hurricane made landfall at peak intensity, the most intense Atlantic hurricane landfall. Hurricane Camille made landfall in Waveland, Mississippi with a pressure of 900 mbar ( hPa ; 26.58 inHg ), making it the second most intense Atlantic hurricane landfall. Though it weakened slightly before its eventual landfall on the Yucatán Peninsula, Hurricane Gilbert maintained a pressure of 900 mbar ( hPa ; 26.58 inHg ) at landfall, making its landfall the second strongest, tied with Camille. Similarly, Hurricane Dean made landfall on the peninsula, though it did so at peak intensity and with a higher barometric pressure ; its landfall marked the fourth strongest in Atlantic hurricane history. In 1924, a hurricane made landfall on the western tip of Cuba with a pressure of 910 mbar ( hPa ; 26.88 inHg ), making it the fifth - strongest Atlantic hurricane landfall. Hurricane Maria made landfall in Puerto Rico shortly after its peak intensity, with a pressure of 917 mbar ( hPa ; 27.08 inHg ), making it the eighth - strongest Atlantic hurricane landfall. Despite being well past its peak intensity, Hurricane Katrina made landfall in Buras - Triumph, Louisiana with a pressure of 920 mbar ( hPa ; 27.17 inHg ), thus making it the tenth - strongest landfall.

Each hurricane season may be impacted by an El Niño or La Niña which contributes to the amount of storms in any given year, and a hurricane with a peak intensity of Category 3 or higher on the Saffir - Simpson Hurricane Scale is classified as major. Most Atlantic hurricane seasons between 1851, and 1930 included 7 or less recorded tropical storms or hurricanes, as well as many seasons between 1930 and 1965. The usage of satellite data was not available until the mid-1960s, which makes early storm counts less reliable. The most active Atlantic hurricane season in recorded history took place in 2005, when a total of 28 storms were counted. The storm count includes 22 hurricanes, of which 7 strengthened to major hurricane status.
