Coastal Flood — Coastal Onslow, NC

Nov 7, 2021

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.
