Storm surge and high waves are likely to cause beach erosion along nearly 80% of sandy beaches and overwash about 50% of the dunes from Florida through North Carolina
To better understand storm impacts on the coast, the USGS National Assessment of Storm-Induced Coastal Change Hazards group is responding to Hurricane Dorian.
The USGS National Assessment of Coastal Change Hazards storm team is responding to Hurricane Dorian by producing predictions of potential coastal change impacts for the Southeastern Atlantic coastline. Storm surge and high waves are likely to cause beach erosion along nearly 80% of sandy beaches and overwash about 50% of the dunes from Florida through North Carolina.

Forecasts showing the timing and magnitude of elevated water levels at the shoreline are available in real-time for the U.S. coastline from Florida through Maine in the Total Water Level and Coastal Change Forecast Viewer.
If additional response activities are initiated by the Coastal Change Hazards team (lidar, photography, or ground surveys) updates will be posted here.
Find additional information and data for Hurricane Harvey, including inland and coastal flood data on the USGS Dorian website.

National Assessment of Storm-Induced Coastal Change Hazards
This project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. The overall objective is to improve real-time and scenario-based predictions of coastal change to support management of coastal infrastructure, resources, and safety.
National Assessment of Coastal Change Hazards
Research to identify areas that are most vulnerable to coastal change hazards including beach and dune erosion, long-term shoreline change, and sea-level rise.
Coastal Change Hazards Portal
Interactive access to coastal change science and data for our Nation’s coasts. Information and products are organized within three coastal change hazard themes: 1) extreme storms, 2) shoreline change, and 3) sea-level rise. Displays probabilities of coastal erosion.
