The NWS alert describes 2 to 4 feet of inundation expected in low-lying shoreline areas. NC-12, the only paved road on Hatteras Island, faces potential overtopping near high tide. Hatteras Island and Ocracoke Island are narrow barrier islands with low-elevation roads on both the ocean and soundside margins. Soundside water levels are also forecast to rise. NWS instructs residents and visitors to avoid unnecessary travel and not to drive through barricades or water of unknown depth.
Ocean surf conditions compound the flooding hazard. The NWS warning forecasts breaking surf of 8 to 14 feet with dangerous rip currents and strong longshore currents along the oceanfront.
