2021 Atlantic hurricane season (Cooper - New)

The 2021 Atlantic hurricane season was a very active Atlantic hurricane season that featured pre-season activity. The season officially started on June 1 and ended on November 30. These dates conventionally delimit the period in each year when most tropical cyclones tend to form in the Atlantic basin. However, as shown by Tropical Storm Ana in May, the formation of tropical cyclones is possible at any time of the year.

The 2021 season proved to be costly and very deadly. Hurricane Henri in late August caused over 1,500 fatalities and $5.3 billion (2001 USD) in damages in Central America, with Mexico and Belize being the hardest-hit. Hurricane Mindy was the season's strongest and most destructive storm, causing over $6 billion in damages in Cuba as a Category 5 hurricane. Mindy then struck southern Florida, which had been devastated by Hurricane Irma in 2017, causing another $17 billion in damages.
