In terms of Accumulated Cyclone Energy (ACE), which measures the strength and duration of tropical storms and hurricanes, the season to date is 10 to 15 percent below the long-term (1991-2020) average. The number of named storms (17) in the basin so far in 2021 is slightly above the long-term average (15) through the end of the month.
