Elevated water levels from Hurricane Florence likely to impact Southeast Atlantic beaches and dunes for several days

The USGS Coastal Change Hazards storm team is predicting coastal change impacts due to the potential for high waves and storm surge along the Southeast Atlantic coast.

In North Carolina where Florence is predicted to make landfall, 75% of sandy beaches are likely to erode and 15% of dunes are likely to overwash. Forecasts showing the timing and magnitude of elevated water levels at the shoreline in the Total Water Level and Coastal Change Forecast Viewer are predicting that water levels will be elevated for several days, increasing the likelihood of overwash and inundation as dunes are eroded through time. Predictions will be updated as conditions change and are available in the Coastal Change Hazards Portal.
