ACE is the result of a storm's winds multiplied by how long it lasted for, so storms that lasted a long time , as well as particularly strong hurricanes , have higher ACE totals. 2066 was active in these terms; with an ACE total of 235. Tropical Depressions and Subtropical storms are not included in season totals.
