are slightly lower this year.
Sea-Surface Temperatures in the Gulf are below average So Far for this season.
This time last year, we were already past Tropical Storms Arlene and Bret, Hurricanes Cindy, Dennis, and Emily, plus Tropical Storm Franklin. TS Gert arrived the 24th of July. Sea-Surface Temperatures (SSTs) played a significant role:
Warmer-than-normal sea-surface temperatures were also a key player in the record number of storms. Tropical cyclones need ocean surface water temperatures of 82 degrees Fahrenheit (F) or greater to fuel the evaporation and rising air that helps create the thunderstorms in a tropical cyclone.
Sea surface temperatures (SST) in the tropical Atlantic and Gulf of Mexico easily surpassed the "hurricane threshold" beginning in July 2005 and continued to climb into the mid- to high 80's through August. These sea surface temperatures are 1 to 3 degrees F above normal. "Hurricane-wise, we are in an incendiary situation," said Bill Patzert, oceanographer at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "These toasty SSTs are high octane fuel for September's hurricanes." September is usually the busiest month for Atlantic hurricanes.

Most of the Gulf of Mexico is cooler than average. Secondly, the central Atlantic is warmer than last year. Thus the SST anomalies are more diffuse this year.
