USGS Coastal Change Hazards Portal shows potential coastal change from Hurrricane Helene

Prior to landfall on the Florida coast on September 26, 2024, the Coastal Change Hazards Team predicted that 63 percent of beaches from Horn Island, MS to Marco Island, FL were very likely to erode at the dunes’ base, 50 percent of dunes were very likely to be overwashed by storm waves, and 32 percent of dunes were expected to be very likely to be inundated (completely submerged) by surge, tide, and waves given worst-case scenario surge and timing of the storm.
