A video shared by FOX Weather Storm Specialist Mike Seidel shows crews working to build up the sand dunes on Highway 12 on Hatteras Island, North Carolina, ahead of impacts from Hurricane Erin.

NCDOT officials said “given the winds, wave heights and storm surge forecast, it likely won’t be enough” to keep NC 12 from flooding at the Outer Banks.

Tropical Storm and Storm Surge Watches have been issued for portions of North Carolina’s Outer Banks as extremely dangerous Hurricane Erin continues to barrel across the Atlantic as a major Category 4 hurricane.

Forecasters are confident it will curl north and away from the eastern U.S., but tropical storm and surge watches were issued for much of North Carolina’s Outer Banks.

By Tuesday morning, Erin had lost some strength from previous days and dropped to a Category 2 hurricane with maximum sustained winds of 110 mph (175 kph), the National Hurricane Center in Miami said.
