A coastal storm formed off the Southeastern U.S. coast during the weekend of November 6-8th, and in tandem with 'King' tides, or high astronomical tides, produced water level rises of up to 2 to 4 feet above ground level for areas of Eastern NC, along with ocean overwash and severe erosion on the Outer Banks. In addition to the coastal flooding, high winds were recorded over 60 mph in some locations, and storm force winds over the coastal waters.

Coastal Flood in HATTERAS ISLAND, NORTH CAROLINA
From 06-NOV-21 20:00:00 to 08-NOV-21 12:00:00 (EST-5)
Reported by: Department of Highways

Coastal flooding, wave run-up, and ocean overwash began affecting Hatteras Island during the evening high tide cycle on Nov. 6th.  Highway 12 in the area of the Cape Hatteras Motel in Buxton was covered in water, with the water flowing across the road at high rates of speed. The next morning's high tide cycle forced a closure of Highway 12 between Rodanthe and Marc Basnight Bridge, as dunes were breached here.  Ocean overwash continued the next two days on November 7th and 8th with each high tide cycle, and Highway 12 remained closed.  Water levels finally receded by the afternoon of November 8th.

The tide gauge at Duck shows that major flood stage (6.5 feet MLLW) was exceeded through multiple high tide cycles.  High water levels combined with breaking waves and wave run up on the beaches, breached dunes along Highway 12 north of Rodanthe causing Highway 12 to be closed for 3 days. The peak value of 6.87 feet (MLLW) was the 4th all time highest value at Duck and the 2nd highest value in a non tropical event.
