Hurricane Erin | North Carolina Residents Prep For Flooding As Erin Approaches The Outer Banks On North Carolina's Outer Banks, Hurricane Erin's storm surge could swamp roads with waves of 15 feet (4.6 meters). Mandatory evacuations were ordered on Hatteras and Ocracoke Islands. More than 1,800 people had left Ocracoke by ferry since Monday. North Carolina Gov. Josh Stein warned residents along the coast to be prepared in case they need to evacuate and declared a state of emergency on Tuesday. Bulldozers shored up the dunes, and on Hatteras, the owners of a pier removed a few planks, hoping the storm surge will pass through without tearing up the structure.
