Large waves and storm surge from Hurricane Maria likely to cause extensive beach erosion along the mid-Atlantic coastline

Press release: Hurricane Maria expected to alter North Carolina, Virginia and Maryland Beaches

The USGS National Assessment of Coastal Change Hazards storm team is predicting coastal change impacts due to the potential for high waves and elevated water levels along the North Carolina coastline as Hurricane Maria comes near to the coast. Predictions will be updated as conditions change and are available in the Coastal Change Hazards Portal. Forecasts showing the timing and magnitude of elevated water levels from Hurricane Maria at the shoreline are available in real-time for the U.S. coastline from North Carolina through Massachusetts in the Total Water Level and Coastal Change Forecast Viewer.

Hurricane Irma

Elevated water levels due to Hurricane Irma caused extensive dune erosion and overwash

Press release: Hurricane Irma to significantly affect beaches from Florida to South Carolina

The USGS National Assessment of Coastal Change Hazards storm team is responding to Hurricane Irma with the following:

Find additional information and data for Hurricane Irma on the USGS Irma website.

Post-storm imagery is available from NOAA National Geodetic Survey.

Hurricane Harvey

Many Texas beaches eroded and overwashed by Hurricane Harvey

Press release: Many Texas Beaches Likely to Erode, Be Overwashed, or Inundated by Hurricane Harvey

The USGS National Assessment of Coastal Change Hazards storm team is responding to Hurricane Harvey with the following:

If additional response activities are initiated, such as lidar and ground surveys, updates will be posted on the Harvey webpage.

Find additional information and data for Hurricane Harvey, including inland and coastal flood data, on the USGS Harvey website.
