2021 Atlantic hurricane season (HurricaneLucas4064)

The 2021 Atlantic hurricane season was an event in the annual formation of tropical cyclones in the Northern Hemisphere. The season officially began on June 1, 2021, and ended on November 30, 2021. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, tropical cyclogenesis is possible at any time of the year.

System Names
The following list of names was used for named storms that formed in the North Atlantic in 2021. The names not retired from this list were used again in the 2027 season. This was the same list used in the 2015 season, with the exceptions of Elsa and Julian, which replaced Erika and Joaquin, respectively. The names Elsa and Julian were used for the first (and only, in the case of Elsa) time this year.

Retirement
On April 8, 2021, at the 44th session of the RA IV hurricane committee, the World Meteorological Organization retired the names Claudette, Elsa, Henri, and Mindy from their rotating naming lists due to the number of deaths and amount of damage they caused, and they will not be used again for another Atlantic hurricane. They will be replaced with Claire, Ellie, Hayden, and Megan for the 2027 season, respectively.
