For the 2011 season NHC will be issuing "Probabilistic Hurricane Storm Surge greater than 2-25 feet" on www.nhc.noaa.gov when a hurricane watch or warning is in effect.

This graphic shows storm surge heights, in feet above normal tide level, which have a 10 percent chance of being exceeded during the next 3 days.  The graphic is based upon an ensemble of Sea, Lake, and Overland Surge from Hurricanes (SLOSH) model runs using the current National Hurricane Center (NHC) official hurricane advisory.  The exceedance heights depend on the historical accuracy of NHCs forecasts of hurricane track, and wind speed, and an estimate of storm size.
