2020 Atlantic hurricane season (Cooper - Alt)

The 2020 Atlantic hurricane season was the most active Atlantic hurricane season since 2010, as well as the costliest since 2017, and the deadliest since 2005.

The season officially began on June 1 and ended on November 30. These dates historically describe the period of year when most tropical cyclones form in the Atlantic basin. However, as shown by Tropical Storm Arthur in March, the formation of tropical cyclones is possible at any time of the year.

Storm names
The following list of names was used for named storms that formed in the North Atlantic in 2020. The names not retired from this list were used again in the 2026 season. This was the same list used in the 2014 season. The names Isaias, Paulette, Rene, Sally, and Teddy were used for the first time this year. Two names, Vicky and Wilfred, were not used during the course of the season.

Retirement
On April 18, 2021, at the 43rd session of the RA IV hurricane committee, the World Meteorological Organization retired the names Edouard, Hanna, Josephine, and Omar from its rotating name lists due to the amount of deaths and damage they caused, and they will not be used again for another Atlantic hurricane. They were replaced with Ethan, Hailey, Judith, and Oliver for the 2026 season.
