2021 Atlantic Hurricane Season

BillLeave a comment

The 2021 Atlantic hurricane season has officially ended. Although all of the official names were used, four of those storms were short-lived or extratropical, and, in my humble opinion, should not have been named (Ana, Odette, Teresa, Wanda). There were officially 21 named storms, but there were really just 17. There were 7 hurricanes of which 4 were major. One of those, Ida, made landfall in the U.S. None of the storms exceeded Category 4. Ida and Sam were the strongest this year at Category 4. The Accumulated Cyclone Energy (ACE) for the season was lower than 2020.
