NASSAU COUNTY REGIONAL
STORM SURGE MAP

Hurricane storm surge zones are based on NOAA's "Sea, Lake and Overland Surge from Hurricanes (SLOSH)" model projections of sea level rise (surge height) associated with category 1-4 hurricanes.  Surge heights have been mapped against coastal terrain to delineate inundation zones for each storm category.  Northwest tracking storms with several possible landfall locations which occur at high tide have been factored in the modeling to produce the worst case flooding for any given area from any given category storm (northwest tracking storms produce the highest surge in the region).  As these zones factor several possible landfalls, no one storm of a given category will inundate all areas delineated for that category storm.
