U.S. EPA’s Climate Ready Water Utilities Initiative has created the online Storm Surge Inundation Map, an interactive tool that illustrates the current worst-case storm surge and inundation scenarios on the American Gulf and Atlantic Coast, including Puerto Rico and the U.S. Virgin Islands. The map combines data layers from FEMA 100 and 500 year flood maps as well as NOAA's Sea, Lake, and Overland Surge from Hurricanes (SLOSH) and National Hurricane Center's coastal county hurricane strike maps.
