The 2021 Atlantic hurricane season was the third most active Atlantic hurricane season. It officially began on June 1, 2021, and ended on November 30, 2021. These dates, adopted by convention, historically describe the period in each year when most Atlantic tropical cyclones form.[1] However, tropical cyclogenesis is possible at any time of the year, as demonstrated by the early formation of Subtropical Storm Ana on May 22, making 2021 the seventh consecutive year that a storm formed before the official start of the season.[2] In June 3 named storms formed during the month making June 2021 the most active June since 1968 and also tied with 1886, 1909, and 1936.

Starting this season, the National Hurricane Center (NHC) began to issue regular Tropical Weather Outlooks on May 15, two weeks earlier than it did in the past. This change was implemented in light of the fact that named systems had formed in the Atlantic Ocean prior to the official start of the season in each of the preceding six seasons.[3]

The storm later dissipated the next day. This storm killed 14 people in Alabama, 4 of which were direct.

Category 1 hurricane

This made it the earliest fifth tropical cyclone to form in the Atlantic since reliable records begun in 1851. This is also the second earliest storm to form this far east in the Main Development Region, only behind the 1933 Trinidad hurricane. This storm rapidly moved towards the Lesser Antillies at 30 mph after it became a tropical storm.

These names will be used for named storms that form in the North Atlantic in 2021. Retired names, if any, will be announced by the World Meteorological Organization in the spring of 2022. The names not retired from this list will be used again in the 2027 season. This is the same list used in the 2015 season, with the exceptions of Elsa and Julian, which replaced Erika and Joaquin. The names Elsa, Julian, Rose, Sam, Teresa, Victor, and Wanda was used for the first time this year.

Season effects[change | change source]

This is a table of all of the storms that have formed in the 2021 Atlantic hurricane season. It includes their duration, names, landfall(s)–denoted by bold location names – damages, and death totals. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but were still related to that storm. Damage and deaths include totals while the storm was extratropical, a wave, or a low, and all of the damage figures are in 2021 USD.
