From what I read in the storm surge warning, they are expecting 2-4 feet of inundation on the sound side of the OBX which will definitely cause some big problems if that verifies. Already the coast guard hydro gauge is measuring nearly 3 feet and moderate flooding begins at 3.5 feet. Cedar Island is at 2.4 feet and moderate flooding begins at 4 feet there. The duration of the winds and large area will continue to pile the waters up the next 24 hours and usually experience around this area tells me the sounds rise a bit more than forecast most of the time.
Looks like that includes the regular tides as well. I was talking about the water rise in addition to normal tides being 2 to 2.5 ft. Regular tides are about 2ft or so above MSL.
