Sea Surface temperatures are at the heart of any attempt to analyze seasonal hurricane activity, since SSTs change slowly and have a major impact on both the number of storms that form and their intensity. For example, the record-breaking Hurricane Season of 2005 had the warmest SSTs ever observed in the tropical Atlantic.

Sea Surface Temperature (SST) comparison between April 11, 2008 (top) and April 11, 2005 (bottom). SSTs were at record high levels in 2005, and are much cooler in 2008 over the Main Development Region (MDR) for hurricanes.

The NOAA CFS model is predicting La Niña conditions and lower than average wind shear for the coming hurricane season.
