Disclaimer

The data and maps in this tool illustrate the height of possible storm surge flooding under certain scenarios, and do not account for erosion, subsidence, sea-level change or future construction. Water levels are based on storm surge scenarios in the referenced SLOSH MOM tide scenario. The data, maps, and information provided should only be used as a tool for general education/awareness of the storm surge hazard at a city/community level (not for a parcel level/grid cell assessment). The SLOSH MOM storm surge risk data used to create these maps are constrained by the extent of the SLOSH grids and users should be aware that risk due to storm surge flooding could extend beyond the areas depicted in these maps. This map should not be used to replace the maps used for hurricane evacuation zones. Hurricane evacuation zones are drawn at a local and state level and consider additional information and specific criteria for a particular region in addition to the storm surge hazard. Users are urged to consult local officials for flood risk inside the hatched areas marked as leveed areas in the map. The data and maps in this tool are provided "as is", without warranty to their performance, merchantable state, or fitness for any particular purpose. The entire risk associated with the results and performance of these data is assumed by the user. This tool should be used strictly as a planning reference and storm surge risk awareness tool and not for navigation, permitting, legal, or regulatory purposes. Any conclusions drawn from the analysis of this information are not the responsibility of the National Weather Service, National Hurricane Center, Office for Coastal Management, or its partners.

The Caribbean Coastal and Ocean Observing System (CARICOOS) provides CERCA products, published by NOAA, as a service to the public. These tools were developed solely for the purpose of informing and educating about coastal risks and caution should be exercised when analyzing and interpreting the data and information. CARICOOS is not responsible for the inappropriate use of these tools.

INFORMATION

This national depiction of storm surge flooding vulnerability helps people living in hurricane-prone coastal areas. These maps make it clear that storm surge is not just a beachfront problem, with the risk of storm surge extending many miles inland from the immediate coastline in some areas.

INSTRUCTIONS

To view the storm surge flooding associated with a hurricane category, click the category buttons on the top right. Alternatively, use the Play / Pause button, also on the top right, to start or pause an animation showing the storm surge flooding for each hurricane category. You can zoom and pan the map like any other Google Map.
