Season summary

The season's activity was reflected with a cumulative accumulated cyclone energy

 (ACE) rating of 63. 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 34 knots (39 mph, 63 km/h) or tropical storm strength. Subtropical storms are not included in the ACE value.
