In December, private weather forecaster WSI Corp predicted a relatively active hurricane season for 2009, with 13 named storms, 7 hurricanes and 3 intense hurricanes.

However now, after reviewing the cool tropical Atlantic Ocean temperatures and a waning of the recent La Nina event, WSI is revising their forecast. The company now expects 11 named storms, 6 hurricanes and 2 intense hurricanes over the 2009 season.

The 2009 forecast numbers are quite close to the long-term- that is, 1950 to 2008 - average of 9.8 named storms, 6 hurricanes, and 2.5 intense hurricanes.

Officially the Atlantic hurricane season is from June 1st to November 30th.
