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 U.S. Gulf and Atlantic Coasts, including Puerto Rico and the U.S. Virgin Islands. The worst case scenarios are derived from data layers from FEMA 100 and 500 year flood maps as well as NOAA's Sea, Lake, and Overland Surge from Hurricanes (SLOSH) and the National Hurricane Center's coastal county hurricane strike maps.
EPA’s water security division also released a mobile app, Water Utility Response On the Go, which provides links to NOAA weather information such as national forecast charts, NOAA’s storm prediction center and quantitative precipitation forecasts. The app also enables users to sign up for stream gauge notifications from USGS. Contacts for utility emergency response partners, such as local Water/Wastewater Agency Response Network (WARN) contacts and emergency management agency contacts, are also provided, based on user location.
