2021 Atlantic hurricane season
Period of formation of tropical cyclones in the North Atlantic Ocean in 2021 / From Wikipedia, the free encyclopedia
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]
