Dare County warns about coastal flooding and NC 12 impact
Published 11:46 am Friday, September 18, 2020
Portions of the Outer Banks — particularly Hatteras Island — are expected to experience coastal flooding, high winds, storm surge, beach erosion and strong rip currents as the remnants of Sally pass over the area and the impacts from distant Hurricane Teddy are felt throughout the weekend.
The National Weather Service at Newport/Morehead City reports that high astronomical tides will bring the threat of coastal flooding around the time of each high tide on Friday, Saturday and Sunday. Friday evening’s high tide will occur at approximately 9 p.m., Saturday’s high tides will take place at approximately 9 a.m. and 10 p.m. and Sunday morning’s high tide will be around 10 a.m.
Dare County Emergency Management is asking visitors to be mindful of Hurricane Teddy and the remnants of Sally and is encouraging travelers to and from Hatteras Island to consider leaving early or to adjust their arrival and departure times to avoid high tide.
Ocean overwash along areas of N.C. Highway 12 on Hatteras Island could cause temporary closures of the roadway during periods of high tide. Those residing within oceanfront properties are advised to take action to protect their property from flooding.
Minor to moderate coastal flooding is forecast to occur with 2-4 feet of inundation likely. Strong winds beginning on Friday and extending into the weekend could bring more extensive coastal flooding impacts.
In addition to the impacts the area will see from the remnants of Sally, strong, long-period swell from Hurricane Teddy — which is currently a Category 4 hurricane headed for Bermuda — will also bring an increased potential for significant beach erosion and ocean overwash as the storm passes well offshore of the Outer Banks late Sunday and into Monday.
Strong winds and rough surf will also result in an increased risk of strong rip currents. Even the most experienced swimmers are advised to stay out of the ocean due to the dangerous surf conditions that will be created in all areas of Dare County throughout the weekend.
