Busy 2012 hurricane season continues decades-long high activity era in the Atlantic
Four U.S. land-falling storms include devastating Sandy and Isaac
November 30 marks the end of the 2012 Atlantic Hurricane season, one that produced 19 named storms, of which 10 became hurricanes and one became a major hurricane. The number of named storms is well above the average of 12. The number of hurricanes is also above the average of six, but the number of major hurricanes is below the average of three.
Based on the combined number, intensity, and duration of all tropical storms and hurricanes, NOAA classifies the season as above-normal. 2012 was an active year, but not exceptionally so as there were 10 busier years in the last three decades.
This season marks the second consecutive year that the mid-Atlantic and Northeast suffered devastating impacts from a named storm. Sandy, and Irene last year, caused fatalities, injuries, and tremendous destruction from coastal storm surge, heavy rainfall, inland flooding, and wind.
