A variety of agencies in the USA have been involved in predicting and accessing damage from Hurricane Joaquin.
Coastal change experts from the U.S. Geological Survey (USGS) recently warned that although the path of Hurricane Joaquin continues to move farther offshore, a high probability of dune erosion existed along parts of the Atlantic coast, from the North Carolina Outer Banks to Cape Cod.
Area which could be affected include the Outer banks, Virginia, and Maryland, New England, the New Jersey and New York coast.
USGS issues coastal-change forecasts, which integrate information produced by both the USGS and National Oceanic and Atmospheric Administration and its National Hurricane Center. The forecasts are posted daily to the agency's Coastal Change Hazards Portal.
