The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 76. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. ACE is only calculated for full advisories on tropical systems at or exceeding or tropical storm strength. Although officially, subtropical cyclones, such as the first storm, are excluded from the total, the figure above includes periods when storms were in a subtropical phase.
