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

Release Date:

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.

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.
