The 1972 Atlantic hurricane season was a significantly below average season, having only seven named storms, four fully tropical storms and three subtropical storms. It officially began on June 1, 1972, and lasted until November 30, 1972. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first storm, Subtropical Storm Alpha, developed on May 23 off the Southeast United States and struck Florida, causing minor damage and two fatalities. Although several other tropical depressions developed, only Tropical Depression Five is known to have affected land.
The 1979 Atlantic hurricane season was the first season to include both male and female names, as well as the common six-year rotating lists of tropical cyclone names. 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 slightly below average, with nine systems reaching tropical storm intensity. The first system, an unnumbered tropical depression, developed north of Puerto Rico on June 9. Two days later, Tropical Depression One formed and produced severe flooding in Jamaica, with 40 deaths and about $27 million (1979 USD) in damage. Tropical Storm Ana caused minimal impact in the Lesser Antilles. Hurricane Bob spawned tornadoes and produced minor wind damage along the Gulf Coast of the United States, primarily in Louisiana, while the remnants caused flooding, especially in Indiana. Tropical Storm Claudette caused extensive flooding in Texas due to torrential rainfall, resulting in two deaths and about $750 million in damage.
The 1981 Atlantic hurricane season featured direct or indirect impacts from nearly all of its 12 tropical or subtropical storms. Overall, the season was fairly active, with 22 tropical depressions, 12 of which became a namable storm, while 7 of those reached hurricane status and 3 intensified into major hurricanes. The season officially began on June 1, 1981, and lasted until November 30, 1981. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. However, tropical cyclogenesis can occur before these dates, as demonstrated with the development of two tropical depressions in April and Tropical Storm Arlene in May. At least one tropical cyclone formed in each month between April and November, with the final system, Subtropical Storm Three, becoming extratropical on November 17, 1981.
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 1988 Atlantic hurricane season was a near average season that proved costly and deadly, with 15 tropical cyclones directly affecting land. The season officially began on June 1, 1988, and lasted until November 30, 1988, although activity began on May 30 when a tropical depression developed in the Caribbean. The June through November dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first cyclone to attain tropical storm status was Alberto on August 8, nearly a month later than usual. The final storm of the year, Tropical Storm Keith, became extratropical on November 24.
The 2006 Atlantic hurricane season was the least active since 1997 as well as 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 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 1949 Atlantic hurricane season was the last season that tropical cyclones were not publicly labeled by the United States Weather Bureau. It officially began on June 15, and lasted until November 15. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first storm, a tropical depression, developed in the northern Gulf of Mexico on August 14. The final system, Tropical Storm Sixteen, dissipated in the southwestern Caribbean Sea on November 5. It was a fairly active season, featuring 16 tropical storms and seven hurricanes. Two of these strengthened into major hurricanes, which are Category 3 or higher on the Saffir–Simpson hurricane wind scale.
The 1941 Atlantic hurricane season was the period during 1941 in which tropical cyclones formed in the Atlantic Basin. It was a relatively inactive hurricane season, with only six known storms. It officially began on June 16, 1941, and lasted until November 1, 1941. These dates delimit the period of each year when most tropical cyclones tend to form in the Atlantic basin. Of the six cyclones, four attained hurricane status, and three became major hurricanes. The active season had an abnormally late start; the first system formed on September 11, nearly three months after the official beginning date. The season was also short-lived, as all six storms developed in rapid succession. On September 23, three hurricanes existed simultaneously in the Atlantic basin.
The 1936 Atlantic hurricane season was fairly active, with 20 tropical cyclones recorded, 17 of which became tropical storms. Seven storms became hurricanes, of which one became a major hurricane. In addition, the season was unusual in the fact that no storms moved across large portions of the Caribbean Sea. Seven storms, including three hurricanes, struck the United States.
The name Gabrielle has been used for eight tropical cyclones worldwide, six in the Atlantic Ocean and two in the Indian Ocean.
The 1893 Atlantic hurricane season ran through the summer and the first half of fall in 1893. The 1893 season was fairly active, with 12 tropical storms forming, 10 of which became hurricanes. Of those, five became major hurricanes. This season proved to be a very deadly season, with two different hurricanes each causing over 2,000 deaths in the United States; at the time, the season was the deadliest in U.S. history. The season was one of two seasons on record to see four Atlantic hurricanes active simultaneously, along with the 1998 Atlantic hurricane season. Additionally, August 15, 1893 was the only time since the advent of modern record keeping that three storms have formed on the same day until 2020 saw Wilfred, Alpha, and Beta forming on the same day.
The 1889 Atlantic hurricane season ran through the summer and the first half of fall in 1889. In the 1889 Atlantic season there were nine tropical storms and six hurricanes. However, due to scarce technology and the fact that only storms that affected populated land or ships were recorded, the actual total could be higher.
Tropical Storm Debby was a weak but costly tropical cyclone that affected the Lesser Antilles in September 1994. It was the fourth named tropical storm of the 1994 Atlantic hurricane season; it developed on September 9 east of Barbados. Debby made landfall on Saint Lucia early on September 10, producing heavy rainfall and tropical storm-force wind gusts. The rains caused flooding and landslides, damaging about half of the island's banana plantations. Several villages were isolated after roads and bridges were damaged. Damage totaled about $103 million (1994 USD). On nearby Dominica, Debby damaged crops and fisheries.
The 1994 Atlantic hurricane season was the final season in the most recent negative Atlantic multidecadal oscillation period of tropical cyclone formation within the basin. Despite the below average activity, the season was very deadly, with almost 97% of deaths occurring during Hurricane Gordon, a devastating late-season tropical cyclone that severely impacted the Caribbean Sea, the Greater Antilles and the United States, and one of the longest-lived Atlantic hurricanes on record at the time. The season produced seven named tropical cyclones and three hurricanes, a total below the seasonal average. The season officially started on June 1 and ended on November 30, dates which conventionally limit the period during which most tropical cyclones form in the Atlantic Ocean. The first tropical cyclone, Tropical Storm Alberto, developed on June 30, while the last storm, Hurricane Gordon, dissipated on November 21. The season was unusual in that it produced no major hurricanes, which are those of Category 3 status or higher on the Saffir–Simpson hurricane scale. The most intense hurricane, Hurricane Florence, peaked as a Category 2 storm with winds of 110 mph (180 km/h). Aside from Chris, Florence, and Gordon, none of the storms exceeded tropical storm intensity.
The 2009 Atlantic hurricane season was a below-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.
During 2020, tropical cyclones formed within seven different tropical cyclone basins, located within various parts of the Atlantic, Pacific and Indian Oceans. During the year, 141 tropical cyclones formed in bodies of water known as tropical cyclone basins. Of these, 104, including three subtropical cyclones in the South Atlantic Ocean and three tropical-like cyclones in the Mediterranean, were named by various weather agencies when they attained maximum sustained winds of 35 knots. The strongest storm of the year was Typhoon Goni, peaking with a pressure of 905 hPa (26.72 inHg) and with 10-minute sustained winds of 220 km/h (140 mph). The deadliest storm of the year was Hurricane Eta which caused 175 fatalities and another 100+ to be missing in Central America and the US, while the costliest storm of the year was Hurricane Laura, with a damage cost around $19.1 billion in the Greater Antilles, The Bahamas, and the Gulf Coast of the United States.
During 2021, tropical cyclones formed in seven major bodies of water, commonly known as tropical cyclone basins. Tropical cyclones will be assigned names by various weather agencies if they attain maximum sustained winds of 35 knots. During the year, one hundred forty-five systems have formed and ninety-one were named, including one subtropical depression and excluding one system, which was unofficial. One storm was given two names by the same RSMC. The most intense storm of the year was Typhoon Surigae, with maximum 10-minute sustained wind speeds of 220 km/h (140 mph) and a minimum pressure of 895 hPa (26.43 inHg). The deadliest tropical cyclone was Typhoon Rai, which caused 410 fatalities in the Philippines and 1 in Vietnam, while the costliest was Hurricane Ida, which caused an estimated $75.25 billion USD in damage after striking Louisiana and the Northeastern United States. Six Category 5 tropical cyclones formed during the year, tying 2003.
