Threat Summary

Low pressure will move from off the north Florida coast this evening to just off

the North Carolina coast late Friday. Gale force northeast winds will develop this evening and continue into Friday night. As the low begins to slide east of the coast later Friday and Friday night, winds will become more northerly. Wind advisories for winds of 25 to 35 mph with gusts to 45 mph are in effect for Carteret County and the Outer Banks through 7 am Saturday morning.

The strong winds will create large waves with high surf conditions through Friday night, mainly from Cape Lookout north. The prolonged strong winds will also lead to increased water levels over the southern Pamlico Sound and ocean side beaches north of Cape Hatteras. Water levels are expected to reach 2 to 3 feet above normal, producing mainly minor coastal flooding. Coastal Flood Advisories remain in effect into Saturday morning for oceanside north of Cape Hatteras and for the southern Pamlico Sound.

The increased water levels and high surf may lead to some ocean over-wash over the Outer Banks possibly impacting Highway 12 especially Friday and Friday Night. High Surf Advisories are also in effect for Outer Banks Dare County south to Cape Lookout into Saturday morning.

Rain will be moderate to heavy at times. Total rainfall amounts will range from one to two inches across most of eastern North Carolina with the heaviest amounts along the Crystal Coast.
