 The season's activity was reflected with a cumulative accumulated cyclone energy (ACE) rating of 121. ACE, broadly speaking, is 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 values. ACE is only calculated for full advisories on tropical systems at or exceeding 34 knots (39 mph, 63 km / h) or tropical storm strength.
