2021 Atlantic hurricane season

The 2021 Atlantic hurricane season is a future event in the annual tropical cyclone season in the Northern Hemisphere. The season officially begins on June 1, 2021, and ends 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, the formation of tropical cyclones is possible at any time of the year.

In advance of, and during, each hurricane season, several forecasts of hurricane activity are issued by national meteorological services, scientific agencies, and noted hurricane experts. These include forecasters from the United States National Oceanic and Atmospheric Administration (NOAA)'s National Hurricane and Climate Prediction Center, Tropical Storm Risk, the United Kingdom's Met Office, and Philip J. Klotzbach, William M. Gray and their associates at Colorado State University (CSU). The forecasts include weekly and monthly changes in significant factors that help determine the number of tropical storms, hurricanes, and major hurricanes within a particular year. According to NOAA and CSU, the average Atlantic hurricane season between 1981 and 2010 contained roughly 12 tropical storms, six hurricanes, three major hurricanes, and an accumulated cyclone energy (ACE) index of 66–103 units.[4][3] NOAA typically categorizes a season as either above-average, average, or below-average based on the cumulative ACE Index, but the number of tropical storms, hurricanes, and major hurricanes within a hurricane season are considered occasionally as well.[4]

Pre-season forecast

On December 9, 2020, the Tropical Storm Risk (TSR) issued an extended range forecast for the 2021 season, predicting activity that is above normal. In this report, the organization predicts 16 named storms, 7 hurricanes and 3 major hurricanes. The main factor behind their prediction is the expected development of a weak La Niña by the third quarter of 2021.[3]


Storm names

The following 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, respectively.

If all 21 names on this list are used, any subsequent storms in 2021 will take their names from the Greek alphabet, which occurred in the 2005 and 2020 seasons.[5]

Season effects

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.
