began issuing tropical cyclone warnings as a collaborative observation network for cities along the U.S. coastline, and the season was defined between June 15 and November 15. In 1964, the season was extended to begin on June 1 and end on November 30, which remains the official length of the season. About 97% of all tropical cyclones form within this time span, and activity usually peaks between August and October. After Tropical Storm Ana formed in May 2015, former

Chronology

Tropical cyclones have been named in the Atlantic since the
1947 Atlantic hurricane season The 1947 Atlantic hurricane season was the first Atlantic hurricane season to have tropical storms labeled by the United States Air Force. The season officially began on June 16, 1947, and ended on November 1, 1947. These dates conven ...

since 1968. The National Hurricane Center issues names for tropical and subtropical cyclones once their winds reach 39 mph (63 km/h). Before 1950, storms were numbered based on their appearance in the Atlantic hurricane database; tropical depressions were unnumbered. Storms before 1851 are unofficial and are not part of the official Atlantic hurricane best track. In addition, a hurricane from May 1863, labeled "Amanda", is included after being rediscovered in 2013. The wind speeds listed are maximum one-minute average sustained winds, and the pressure is the minimum

For deaths, "None" indicates that there were no reports of fatalities; death tolls listed as "several" mean there were fatalities reported, but an exact total is unavailable.

Storms were most likely to occur in May, followed by December. Out of all recorded storms in the database, only one cyclone was reported in the month of March; the 1908 March hurricane, as well as one tropical storm in February, which was the 1952 Groundhog Day Storm. In addition, only three tropical or subtropical cyclones formed in April – a subtropical storm in 1992, Tropical Storm Ana of 2003, and Arlene of 2017. A hurricane in 1938, a tropical storm in 1951, a subtropical storm in 1978, and Hurricane Alex of 2016 occurred in January. Of all cyclones during the off-season,

No hurricanes have ever made landfall in the United States during December, although at one point a storm in 1925 was believed to have done this.
