2021 Hypothetical Atlantic hurricane season

The 2021 Atlantic hurricane season was a very active season that produced 22 tropical cyclones, of which 19 became named storms, 10 became hurricanes, and 4 became major hurricanes. The season officially started on June 1st, 2023, although the season's first storm, Hurricane Ana, developed in late May, before the official start of the season. The season's strongest storm was Hurricane Larry, which reached Category 5 strength on the Saffir-Simpson scale with wind speeds of up to 170 miles per hour and a minimum pressure of 915 millibars. The season also featured Hurricane Rose, which reached Category 4 intensity with winds of 145 miles per hour. Two other major hurricanes, Henry and Mindy, also developed and both reached Category 3 intensity.

Hurricane Ana
On May 18th, a front exited the United States and entered the Atlantic Ocean. Moisture embedded within the system allowed the formation of a subtropical depression on May 19th. More moisture and warm air allowed the depression to become fully tropical and strengthen into Tropical Storm Ana the next day. Ana began to track northeast over the Atlantic Ocean, remaining well off the coast of the Carolinas.

Retirement
In the spring of 2022, the World Meteorological Association retired the names Henri, Larry, and Rose from their rotating name lists and will never be used to name another Atlantic tropical cyclone. They were replaced by Hayden, Lonnie, and Rachel, respectively for the 2027 season.
