The 2003 Atlantic hurricane season was a very active season with tropical cyclogenesis occurring before and after the official bounds of the season—the first such occurrence since the 1970 season. The season produced 21 tropical cyclones, of which 16 developed into named storms; seven of those attained hurricane status, of which three reached major hurricane status. The strongest hurricane of the season was Hurricane Isabel, which reached Category 5 status on the Saffir–Simpson hurricane scale northeast of the Lesser Antilles; Isabel later struck North Carolina as a Category 2 hurricane, causing $3.6 billion in damage and a total of 51 deaths across the Mid-Atlantic region of the United States.
The 2000 Atlantic hurricane season was a fairly active hurricane season, but featured the latest first named storm in a hurricane season since 1992. The hurricane season officially began on June 1, and ended on November 30. It was slightly above average due to a La Niña weather pattern although most of the storms were weak. It was also the only season to have two of the storms affect Ireland. The first cyclone, Tropical Depression One, developed in the southern Gulf of Mexico on June 7 and dissipated after an uneventful duration. However, it would be almost two months before the first named storm, Alberto, formed near Cape Verde; Alberto also dissipated with no effects on land. Several other tropical cyclones—Tropical Depression Two, Tropical Depression Four, Chris, Ernesto, Nadine, and an unnamed subtropical storm—did not impact land. Five additional storms—Tropical Depression Nine, Florence, Isaac, Joyce, and Leslie—minimally affected land areas.
The 1999 Atlantic hurricane season was a fairly active season, mostly due to a persistent La Niña that developed in the latter half of 1998. It had five Category 4 hurricanes – the highest number recorded in a single season in the Atlantic basin, previously tied in 1933 and 1961, and later tied in 2005 and 2020. The season officially began on June 1, and ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first storm, Arlene, formed on June 11 to the southeast of Bermuda. It meandered slowly for a week and caused no impact on land. Other tropical cyclones that did not affect land were Hurricane Cindy, Tropical Storm Emily, and Tropical Depression Twelve. Localized or otherwise minor damage occurred from Hurricanes Bret, Gert, and Jose, and tropical storms Harvey and Katrina.
The 1982 Atlantic hurricane season was an extremely inactive Atlantic hurricane season with five named tropical storms and one subtropical storm. Two storms became hurricanes, one of which reached major hurricane status. The season officially began on June 1, 1982, and lasted until November 30, 1982. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. Activity started early with Hurricane Alberto forming on the first day of the season. Alberto threatened the Southwestern Florida coast as a tropical storm, meadering offshore in the southeastern Gulf of Mexico and causing 23 fatalities in Cuba. The next system, a subtropical storm, formed later in June and affected the same area as Alberto, causing $10 million in damage.
The 1986 Atlantic hurricane season was a very inactive season that produced 10 depressions, 6 named storms, 4 hurricanes, and no major hurricanes. The season officially began on June 1, 1986, and lasted until November 30, 1986. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. During the 1986 season, the first subtropical depression formed in the first week of June, while the last tropical cyclone dissipated at the end of the third week of November. The 1986 season had lower than average activity because of an ongoing El Niño event, and was the least active season in the North Atlantic since the 1983 Atlantic hurricane season. This was also the first season since 1972 to have no major hurricanes.
The 2006 Atlantic hurricane season was the least active in the basin since 1997, with nine named storms as well as an additional unnamed tropical storm identified by the National Hurricane Center. 2006 was the first season since 2001 in which no hurricanes made landfall in the United States, and was the first since 1994 in which no tropical cyclones formed during October. Following the intense activity of 2003, 2004, and 2005, forecasters predicted that the 2006 season would be only slightly less active. Instead, it turned out to be a below average season, as activity was slowed by a rapidly forming moderate El Niño event, the presence of the Saharan Air Layer over the tropical Atlantic, and the steady presence of a robust secondary high-pressure area to the Azores High centered on Bermuda. There were no tropical cyclones after October 2.
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.
Hurricane Maria was an Atlantic hurricane which formed in September 2005 during the annual hurricane season. Maria was the thirteenth named storm, sixth hurricane, and fourth major hurricane of the record-breaking season. Maria formed in the central Atlantic on September 1 and tracked to the northwest, strengthening as it moved over warm waters. The storm reached its peak intensity on September 5 east of Bermuda and gradually weakened before becoming extratropical on September 10. Maria did not affect any land as a tropical cyclone, but Maria brought tropical storm-force winds to Iceland as an extratropical cyclone and produced heavy rain and three fatalities in Norway.
The 2006 Atlantic hurricane season was a cycle of the annual tropical cyclone season in the Atlantic Ocean in the Northern Hemisphere. The season officially began on June 1, 2006, and ended on November 30, 2006. These dates, adopted by convention, historically describe the period in each year when most subtropical or tropical cyclogenesis occurs in the Atlantic Ocean. The first storm to form in 2006 was Tropical Storm Alberto on June 10; the last, Hurricane Isaac, dissipated on October 2.
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.
The 1983 Atlantic hurricane season was an event in the annual tropical cyclone season in the north Atlantic Ocean. It was the least active Atlantic hurricane season in 53 years, during which four storms formed. The season officially began on June 1, 1983 and ended November 30, 1983. These dates, adopted by convention, historically describe the period in each year when most systems form. The first named storm, Hurricane Alicia, formed on August 15. The last storm of the season, Tropical Storm Dean, dissipated on September 30.
Hurricane Humberto was a moderately powerful hurricane that briefly affected Bermuda in September 2001. It was the eighth named storm of the season, as well as the fourth hurricane. It formed on September 21 between Puerto Rico and Bermuda, partially related to previous Hurricane Gabrielle. Humberto passed about 140 miles (230 km) west of Bermuda, which spared the island with its strongest winds. After weakening and believed to be on the verge of dissipating, Humberto unexpectedly restrengthened to the southeast of Atlantic Canada. The intensification was short-lived and the storm dissipated on September 27. There were a series of significant observational flights into the hurricane that produced a wealth of data on the structure of hurricanes.
The 1987 Atlantic hurricane season was an event in the annual Atlantic hurricane season in the north Atlantic Ocean. It was a below-average season, having fewer named storms than in a normal year, that resulted in little impact throughout the Atlantic basin; the United States recorded no hurricane-related fatalities, making the 1987 season the fourth to do so since 1976. The season officially began on June 1, 1987 and ended November 30, 1987. These dates, adopted by convention, historically describe the period in each year when most systems form. Even so, a pre-season storm, Tropical Depression One, led to the season's starting on May 25. Storm activity ended several weeks early; the final storm of the season, Tropical Depression Fourteen, dissipated on November 4.
The 2010 Atlantic hurricane season was the first of three consecutive very active Atlantic hurricane seasons, each with 19 named storms. This above average activity included 12 hurricanes, equaling the number that formed in 1969. Only the 2020 and 2005 seasons have had more, at 14 and 15 hurricanes respectively. Despite the high number of hurricanes, not one hurricane hit the United States making the season the only season with 10 or more hurricanes without a United States landfall. The overall tropical cyclone count in the Atlantic exceeded that in the West Pacific for only the second time on record. The season officially began on June 1 and ended on November 30, dates that conventionally delimit the period during each year when tropical cyclone formation is most likely. The first cyclone, Alex intensified into the first June hurricane since Allison in 1995. The month of September featured eight named storms. October featured five hurricanes, including Tomas, which became the latest on record in a calendar year to move through the Windward Islands. Activity was represented with an accumulated cyclone energy (ACE) value of 165 units, which was the eleventh highest value on record at the time. The activity in 2010 was heightened due to a very strong La Niña, which also led to an inactive Pacific hurricane season.
The 2009 Atlantic hurricane season was a near-average Atlantic hurricane season that produced eleven tropical cyclones, nine named storms, three hurricanes, and two major hurricanes. It officially began on June 1 and ended on November 30, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. The season's first tropical cyclone, Tropical Depression One, developed on May 28, while the final storm, Hurricane Ida, dissipated on November 10. The most intense hurricane, Bill, was a powerful Cape Verde-type hurricane that affected areas from the Leeward Islands to Newfoundland. The season featured the lowest number of tropical cyclones since the 1997 season, and only one system, Claudette, made landfall in the United States. Forming from the interaction of a tropical wave and an upper-level low, Claudette made landfall on the Florida Panhandle with maximum sustained winds of 45 mph (70 km/h) before quickly dissipating over Alabama. The storm killed two people and caused $228,000 in damage.
The 1999 Atlantic hurricane season was an event in the annual tropical cyclone season in the north Atlantic Ocean. This Atlantic hurricane season saw a near-average number of named tropical storms, though five of them became dangerous hurricanes of Category 4 intensity on the 5-level Saffir–Simpson scale, the most in a single season since 1886. The season officially began on June 1, 1999 and ended on November 30, 1999. These dates, adopted by convention, historically describe the period in each year when most tropical systems form. This season's first storm, Tropical Storm Arlene, formed on June 11, while the last, Hurricane Lenny, dissipated on November 23.
The 2015 Atlantic hurricane season was the last of three consecutive below average Atlantic hurricane seasons. It produced twelve tropical cyclones, eleven named storms, four hurricanes, and two major hurricanes. The Accumulated Cyclone Energy (ACE) for the season was 68% of the long-term median value. The hurricane season officially began on June 1, 2015, and ended on November 30, 2015. These dates historically describe the period each year when most tropical cyclones form in the North Atlantic basin. However, the first named storm, Ana, developed on May 8, nearly a month before the official start of the season, the first pre-season cyclone since Beryl in 2012 and the earliest since Ana in 2003. The formation of Ana marked the start of a series of seven consecutive seasons with pre-season activity, spanning from 2015 to 2021. The season concluded with Kate transitioning into an extratropical cyclone on November 11, almost three weeks before the official end.
The 2014 Atlantic hurricane season was a below-average hurricane season in terms of named storms and major hurricanes, though average in terms of number of hurricanes overall. It produced nine tropical cyclones, eight of which became named storms; six storms became hurricanes and two intensified further into major hurricanes. The season officially began on June 1, and ended on November 30. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin. The first storm of the season, Arthur, developed on July 1, while the final storm, Hanna, dissipated on October 28, about a month prior to the end of the season.
The 2010 Atlantic hurricane season was an event in the annual tropical cyclone season in the north Atlantic Ocean. It was one of the most active Atlantic hurricane seasons since record keeping began in 1851 as 19 named storms formed. The season officially began on June 1, 2010, and ended on November 30, 2010, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. The first storm to form was Hurricane Alex, on June 25; and the last to dissipate was Hurricane Tomas, on November 7.
The 2013 Atlantic hurricane season was an event in the annual hurricane season in the north Atlantic Ocean. It featured below-average tropical cyclone activity, with the fewest hurricanes since the 1982 season. The season officially began on June 1, 2013 and ended on November 30, 2013. These dates, adopted by convention, historically delimit the period in each year when most tropical systems form. The season's first storm, Tropical Storm Andrea formed on June 5, and its final storm, an unnamed subtropical storm, dissipated on December 7. Altogether, there were 13 named tropical storms during the season. Two of which attained hurricane strength, but neither intensified into a major hurricane, the first such occurrence since the 1994 season.
