Update from the National Weather Service at 11:21 p.m, Aug. 3, 2020:

Some changes with the 11 p.m. forecast package. Recon and observations have shown that Isaias has gained some intensity as it nears landfall. As it moves north, the wind field will continue to expand and with that a greater threat of storm surge.

As a result, all areas north of Ocracoke Inlet that had previously been in a Storm Surge Watch have been upgraded to a Storm Surge Warning as well as the coastlines of mainland Hyde and mainland Dare Counties. Peak inundation values have also been raised slightly to 3 to 5 feet. For areas south of Rodanthe, this will be an ocean side threat with dune over-wash possible. There could also be some minor sound side inundation
