Hurricane!

From the NOAA report on the 2004 Hurricane season.

The Atlantic Basin had a more active season than average in 2004 with 15 tropical storms and 9 hurricanes, including 6 major hurricanes. The average (based on data from 1944-1996) is approximately 10 named storms and 6 hurricanes, including 2-3 major hurricanes. The ACE index of hurricane activity also indicates an above average season, with a preliminary value of approximately 220 x104 knots. An average season is anywhere from 66 x104 knots to 103 x104 knots. Hurricane Ivan alone produced an ACE value of 69.9 x104 knots. Its strength and longevity contributed substantially to the cumulative seasonal activity and it holds the record for the greatest consecutive time (7 days) spent with windspeeds of 120 kts/138 mph or greater for any basin. After weakening back to a depression, Ivan also looped southward and then westward through the Atlantic to regenerate into a tropical storm in the Gulf of Mexico. The first named storm of the season, Alex, brushed North Carolina in August before moving northeast and reaching windspeeds of 105 kts (121 mph), category 3 on the Saffir-Simpson scale. The only other storm to reach major hurricane status north of 38N was Hurricane Ellen in 1973 and it reached 100 kts (115 mph). This season is also the most costly hurricane season on record ($42 billion) for the US, with 9 storms affecting its coast. Impacts are described below.
