2007 Atlantic hurricane season
The table on the right shows the Accumulated Cyclone Energy (ACE) for each storm in the season. ACE is, basically 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. While Subtropical Storm Andrea was a named storm of the 2007 season, NOAA does not officially include subtropical storms' ACE ratings in season totals. Andrea's ACE would have been 0.603 104kt² if it was tropical. Values accrued while Gabrielle, Jerry and Olga were subtropical are not included in their totals.
