List of Atlantic hurricane records

Last updated

As of May 2024, there have been 1,727 tropical cyclones of at least tropical storm intensity, 960 at hurricane intensity, and 333 at major hurricane intensity within the Atlantic Ocean since 1851, the first Atlantic hurricane season to be included in the official Atlantic tropical cyclone record. [1] Though a majority of these cyclones 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. [2] The scope of this list is limited to tropical cyclone records solely within the Atlantic Ocean and is subdivided by their reason for notability.

Most active /least active Atlantic hurricane seasons

Most Atlantic hurricane seasons prior to the weather satellite era include seven or fewer recorded tropical storms or hurricanes. As the usage of satellite data was not available until the mid-1960s, early storm counts are less reliable. Before the advent of the airplane or means of tracking storms, the ones recorded were storms that affected mainly populated areas. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated. [3]

With the advent of the satellite came better and more accurate weather tracking. The first satellites sent into space to monitor the weather were known as Television Infrared Observation Satellites (TIROS). In 1961, Hurricane Esther was the first hurricane to be "discovered" through satellite readings. [4] Although this modern invention was now available, the systems were initially not fully active enough to provide daily images of the storms. [5] Data for the North Atlantic region remained sparse as late as 1964 due to a lack of complete satellite coverage. [6]

Due to the above factors, terms such as "ever" or "on record" should be interpreted to mean "since sometime between 1964 and 1978".

The most active Atlantic hurricane season on record in terms of total storms took place in 2020, with 30 documented. The storm count for the 2020 season also includes fourteen hurricanes, of which seven strengthened to major hurricane status. On the converse, the least active season on record in terms of total storms took place in 1914. The 1914 season had just one tropical storm and no hurricanes.

Climatologically speaking, approximately 97 percent of tropical cyclones that form in the North Atlantic develop between 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; [8] as of 2023 there have been 92 tropical cyclones in the off-season, with the most recent being an unnamed subtropical storm in January 2023. 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. [9] Hurricane Able in 1951 was initially thought to be the earliest forming major hurricane; [nb 1] 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. [11] Though it developed within the bounds of the Atlantic hurricane season, [8] [11] Hurricane Audrey in 1957 was the earliest developing Category 4 hurricane on record after it reached the intensity on June 27. [12] However, reanalysis [11] of 1956 to 1960 by NOAA downgraded Audrey to a Category 3, making Hurricane Dennis of 2005 the earliest Category 4 on record in the calendar year on July 8, 2005. [13] That mark stood until surpassed by Hurricane Beryl on June 30, 2024. Beryl would also become the earliest Category 5 two days later, surpassing Hurricane Emily of 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. [8] December, the only month of the year after the hurricane season, has featured the cyclogenesis of fourteen tropical cyclones. [11] The second Hurricane Alice in 1954 was the latest forming tropical storm and hurricane, reaching these intensities on December 30 and 31, respectively. Hurricane Alice and Tropical Storm 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. [14] No storms have been recorded to exceed Category 1 hurricane intensity in December. [11] In 1999, Hurricane Lenny reached Category 4 intensity on November 17 as it took an unusual 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. [15] Based on reanalysis, the devastating Cuba hurricane in 1932 reached Category 5 intensity on November 5, making it the latest in any Atlantic hurricane season to reach this intensity.

Most tropical /subtropical storms formed in each month

The Atlantic hurricane season presently runs from June 1 through November 30 each year, with peak activity occurring between August and October. Specifically, the height of the season is in early to mid-September. [8] Tropical systems that form outside of these months are referred to as "off season", and account for roughly 3% of all storms that form in a given year. [8] All of the records included below are for the most storms that formed in a given month, as the threshold for "fewest" is zero for expected months. Cases where "fewest storms" are unusual include the months when the hurricane season is at its peak.

Intensity

Most intense

Generally speaking, the intensity of a tropical cyclone is determined by either the storm's maximum sustained winds or lowest barometric pressure. 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. [53] Nonetheless, their central pressures are low enough to rank them among the strongest recorded Atlantic hurricanes. [11]

Owing to their intensity, the strongest Atlantic hurricanes have all attained Category 5 classification. Hurricane Opal, the most intense Category 4 hurricane recorded, intensified to reach a minimum pressure of 916 mbar (hPa; 27.05 inHg), [54] a pressure typical of Category 5 hurricanes. [55] Nonetheless, the pressure remains too high to list Opal as one of the ten strongest Atlantic tropical cyclones. [11] Currently, Hurricane Wilma is the strongest Atlantic hurricane ever recorded, after reaching an intensity of 882 mbar (hPa; 26.05 inHg) in October 2005; [53] at the time, this also made Wilma the strongest tropical cyclone worldwide outside of the West Pacific, [56] [57] [58] [59] [60] where seven tropical cyclones have been recorded to intensify to lower pressures. [61] 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. [62] 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. [11] Since the measurements taken during Wilma and Gilbert were documented using dropsonde, this pressure remains the lowest measured over land. [63]

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. [11] 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. [64] In between Rita and Katrina is Hurricane Allen. 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). [63] Hurricane Maria is in tenth place for most intense Atlantic tropical cyclone, with a pressure as low as 908 mbar (hPa; 26.81 inHg). [65] In addition, the most intense Atlantic hurricane outside of the Caribbean Sea and Gulf of Mexico is Hurricane Dorian of 2019, with a pressure of 910 mbar (hPa; 26.9 inHg). [66]

Many of the strongest recorded tropical cyclones weakened prior to their eventual landfall or demise. However, four of the storms remained intense enough at landfall to be considered some of the strongest landfalling hurricanes – four of the ten hurricanes on the list constitute four of the top ten most intense Atlantic landfalls in recorded history. The 1935 Labor Day hurricane made landfall at peak intensity, the most intense Atlantic hurricane landfall. [67] 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. [68] 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. [63]

  • Note: Dropsondes have only been GPS-based for use in eyewalls since 1997, [69] and the quantity of aircraft reconnaissance and surface observation stations has changed over time, such that values from storms in different periods may not be 100% consistent.

<span class="mw-page-title-main">1966 Atlantic hurricane season</span>

The 1966 Atlantic hurricane season saw the Weather Bureau office in Miami, Florida, be designated as the National Hurricane Center (NHC) and assume responsibility of tropical cyclone forecasting in the basin. The season officially began on June 1, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. It was an above-average season in terms of tropical storms, with a total of 15. The first system, Hurricane Alma, developed over eastern Nicaragua on June 4 and became a rare major hurricane in the month of June. Alma brought severe flooding to Honduras and later to Cuba, but caused relatively minor impact in the Southeastern United States. Alma resulted in 90 deaths and about $210 million (1966 USD) in damage.

<span class="mw-page-title-main">1969 Atlantic hurricane season</span>

The 1969 Atlantic hurricane season was the most active Atlantic hurricane season since the 1933 season, and was the final year of the most recent positive Atlantic multidecadal oscillation (AMO) era. The hurricane season officially began on June 1, and lasted until November 30. Altogether, 12 tropical cyclones reached hurricane strength, the highest number on record at the time; a mark not surpassed until 2005. The season was above-average despite an El Niño, which typically suppresses activity in the Atlantic Ocean, while increasing tropical cyclone activity in the Pacific Ocean. Activity began with a tropical depression that caused extensive flooding in Cuba and Jamaica in early June. On July 25, Tropical Storm Anna developed, the first named storm of the season. Later in the season, Tropical Depression Twenty-Nine caused severe local flooding in the Florida Panhandle and southwestern Georgia in September.

<span class="mw-page-title-main">1957 Atlantic hurricane season</span>

The 1957 Atlantic hurricane season featured one of the longest-travelling tropical cyclones in the Atlantic basin, Hurricane Carrie. Nevertheless, the season was generally inactive, with eight tropical storms – two of which went unnamed – and three hurricanes, two of which intensified further to attain major hurricane intensity. The season officially began on June 15 and ended on November 15, though the year's first tropical cyclone developed prior to the start of the season on June 8. The final storm dissipated on October 27, well before the official end of the season. The strongest hurricane of the year was Carrie, which reached the equivalent of a Category 4 hurricane on the Saffir–Simpson hurricane scale on two separate occasions in the open Atlantic; Carrie later caused the sinking of the German ship Pamir southwest of the Azores, resulting in 80 deaths.

<span class="mw-page-title-main">1940 Atlantic hurricane season</span>

The 1940 Atlantic hurricane season was a generally average period of tropical cyclogenesis in 1940. Though the season had no official bounds, most tropical cyclone activity occurred during August and September. Throughout the year, fourteen tropical cyclones formed, of which nine reached tropical storm intensity; six were hurricanes. None of the hurricanes reached major hurricane intensity. Tropical cyclones that did not approach populated areas or shipping lanes, especially if they were relatively weak and of short duration, may have remained undetected. Because technologies such as satellite monitoring were not available until the 1960s, historical data on tropical cyclones from this period are often not reliable. As a result of a reanalysis project which analyzed the season in 2012, an additional hurricane was added to HURDAT. The year's first tropical storm formed on May 19 off the northern coast of Hispaniola. At the time, this was a rare occurrence, as only four other tropical disturbances were known to have formed prior during this period; since then, reanalysis of previous seasons has concluded that there were more than four tropical cyclones in May before 1940. The season's final system was a tropical disturbance situated in the Greater Antilles, which dissipated on November 8.

<span class="mw-page-title-main">1935 Atlantic hurricane season</span>

The 1935 Atlantic hurricane season was a near-normal hurricane season. Altogether, ten tropical cyclones developed, eight of which intensified into tropical storms. Five of those tropical storms strengthened into hurricanes, while three of those reached major hurricane intensity. The season ran from June 1 through November 15, 1935.

<span class="mw-page-title-main">1929 Atlantic hurricane season</span>

The 1929 Atlantic hurricane season was among the least active Atlantic hurricane seasons on record, with only five tropical cyclones forming. Three of them intensified into a hurricane, with one strengthening further into a major hurricane. The first tropical cyclone of the season developed in the Gulf of Mexico on June 27. Becoming a hurricane on June 28, the storm struck Texas, bringing strong winds to a large area. Three fatalities were reported, while damage was conservatively estimated at $675,000 (1929 USD).

<span class="mw-page-title-main">1927 Atlantic hurricane season</span>

The 1927 Atlantic hurricane season was a relatively inactive season, with eight tropical storms, four of which became hurricanes. One of these became a major hurricane – Category 3 or higher on the modern day Saffir–Simpson scale. The first system, a tropical depression, developed on August 13, while the final cyclone, a tropical storm, merged with a cold front on November 21. No hurricane made landfall in the United States, in contrast to the four that struck the U.S. in the previous season.

<span class="mw-page-title-main">1921 Atlantic hurricane season</span>

The 1921 Atlantic hurricane season was an active hurricane season, with 12 tropical cyclones forming. Among them, seven became tropical storms, of which five strengthened into hurricanes. Furthermore, two of these strengthened into a major hurricane, Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale, the most since the 1917 season. The first system, a tropical depression, developed on June 1, while the last, a tropical storm, dissipated on November 25. Of note, three tropical cyclones co-existed with another during the season.

<span class="mw-page-title-main">1920 Atlantic hurricane season</span>

The 1920 Atlantic hurricane season featured tropical storms and hurricanes only in the month of September. The first system, a hurricane, developed on September 7 while the last, a tropical depression, transitioned into an extratropical cyclone on October 27. Of note, four of the six cyclones co-existed with another tropical cyclone during the season.

<span class="mw-page-title-main">1919 Atlantic hurricane season</span>

The 1919 Atlantic hurricane season was among the least active hurricane seasons in the Atlantic on record, featuring only five tropical storms. Of those five tropical cyclones, two of them intensified into a hurricane, with one strengthening into a major hurricane Two tropical depressions developed in the month of June, both of which caused negligible damage. A tropical storm in July brought minor damage to Pensacola, Florida, but devastated a fleet of ships. Another two tropical depressions formed in August, the first of which brought rainfall to the Lesser Antilles.

<span class="mw-page-title-main">1912 Atlantic hurricane season</span>

The 1912 Atlantic hurricane season was an average hurricane season that featured the first recorded November major hurricane. There were eleven tropical cyclones, seven of which became tropical storms; four of those strengthened into hurricanes, and one reached major hurricane intensity. The season's first cyclone developed on April 4, while the final dissipated on November 21. The season's most intense and most devastating tropical cyclone was the final storm, known as the Jamaica hurricane. It produced heavy rainfall on Jamaica, leading to at least 100 fatalities and about $1.5 million (1912 USD) in damage. The storm was also blamed for five deaths in Cuba.

<span class="mw-page-title-main">1901 Atlantic hurricane season</span>

The 1901 Atlantic hurricane season was the most active season without a major hurricane – tropical cyclones that reach at least Category 3 on the Saffir–Simpson hurricane wind scale – until 2013. The first system was initially observed in the northeastern Caribbean on June 11. The fourteenth and final system transitioned into an extratropical cyclone near Bermuda on November 5. These dates fall within the period with the most tropical cyclone activity in the Atlantic. Eight of the fourteen tropical cyclones existed simultaneously.

<span class="mw-page-title-main">Timeline of the 2005 Atlantic hurricane season</span>

The 2005 Atlantic hurricane season was an event in the annual tropical cyclone season in the north Atlantic Ocean. It was the second most active Atlantic hurricane season in recorded history, and the most extreme in the satellite era. Officially, the season began on June 1, 2005 and ended on November 30, 2005. These dates, adopted by convention, historically delimit the period in each year when most tropical systems form. The season's first storm, Tropical Storm Arlene, developed on June 8. The final storm, Tropical Storm Zeta, formed in late December and persisted until January 6, 2006. Zeta is only the second December Atlantic storm in recorded history to survive into January, joining Hurricane Alice in 1955.

<span class="mw-page-title-main">Atlantic hurricane</span> Tropical cyclone that forms in the Atlantic Ocean

An Atlantic hurricane is a type of tropical cyclone that forms in the Atlantic Ocean primarily between June and November. The terms "hurricane", "typhoon", and "cyclone" can be used interchangeably to describe this weather phenomenon. These storms are continuously rotating around a low pressure center, which causes stormy weather across a large area, which is not limited to just the eye of the storm. They are organized systems of clouds and thunderstorms that originate over tropical or subtropical waters and have closed low-level circulation, and should not be confused with tornadoes, which are just another type of cyclone. They form over low pressure systems. In the North Atlantic and the Eastern Pacific, the term "hurricane" is used, whereas "typhoon" is used in the Western Pacific near Asia. The more general term "cyclone" is used in the rest of the ocean basins, namely the South Pacific and Indian Ocean.

<span class="mw-page-title-main">Meteorological history of Hurricane Wilma</span>

Hurricane Wilma was the most intense tropical cyclone in the Atlantic basin on record in terms of minimum barometric pressure, with an atmospheric pressure of 882 millibars (26.0 inHg). Wilma's destructive journey began in the second week of October 2005. A large area of disturbed weather developed across much of the Caribbean and gradually organized to the southeast of Jamaica. By late on October 15, the system was sufficiently organized for the National Hurricane Center to designate it as Tropical Depression Twenty-Four.

<span class="mw-page-title-main">Timeline of the 2008 Atlantic hurricane season</span>

The 2008 Atlantic hurricane season was an event in the annual tropical cyclone season in the north Atlantic Ocean. An above-average Atlantic hurricane season, it was the first on record to have a major hurricane in every month from July to November.

<span class="mw-page-title-main">1854 Atlantic hurricane season</span>

The 1854 Atlantic hurricane season featured five known tropical cyclones, three of which made landfall in the United States. At one time, another was believed to have existed near Galveston, Texas in September, but HURDAT – the official Atlantic hurricane database – now excludes this system. The first system, Hurricane One, was initially observed on June 25. The final storm, Hurricane Five, was last observed on October 22. These dates fall within the period with the most tropical cyclone activity in the Atlantic. No tropical cyclones during this season existed simultaneously. One tropical cyclone has a single known point in its track due to a sparsity of data.

<span class="mw-page-title-main">Timeline of the 2009 Atlantic hurricane season</span>

The 2009 Atlantic hurricane season was an event in the annual tropical cyclone season in the North Atlantic Ocean. It was a below-average Atlantic hurricane season with nine named storms, the fewest since the 1997 season. The season officially began on June 1, 2009, and ended on November 30, 2009, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. The first storm to form was Tropical Depression One on May 28, 2009, while the last storm, Hurricane Ida, dissipated on November 10.

<span class="mw-page-title-main">Timeline of the 2012 Atlantic hurricane season</span>

The 2012 Atlantic hurricane season was an event in the annual hurricane season in the north Atlantic Ocean. For the third year in a row there were 19 named storms. The season officially began on June 1, 2012, and ended on November 30, 2012, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. Surprisingly, two preseason storms formed: Alberto on May 19, and Beryl on May 26. This was the first such occurrence since the 1951 season. The final storm to dissipate was Sandy, on October 29. Altogether, ten storms became hurricanes, of which two intensified into major hurricanes.

<span class="mw-page-title-main">Meteorological history of Hurricane Patricia</span>

Hurricane Patricia was the most intense tropical cyclone ever recorded in the Western Hemisphere and the second-most intense worldwide in terms of barometric pressure. It also featured the highest one-minute maximum sustained winds ever recorded in a tropical cyclone. Originating from a sprawling disturbance near the Gulf of Tehuantepec in mid-October 2015, Patricia was first classified a tropical depression on October 20. Initial development was slow, with only modest strengthening within the first day of its classification. The system later became a tropical storm and was named Patricia, the twenty-fourth named storm of the annual hurricane season. Exceptionally favorable environmental conditions fueled explosive intensification on October 22. A well-defined eye developed within an intense central dense overcast and Patricia grew from a tropical storm to a Category 5 hurricane in just 24 hours—a near-record pace. The magnitude of intensification was poorly forecast and both forecast models and meteorologists suffered from record-high prediction errors.
