A strong cold front moving in this afternoon and evening has prompted a coastal flood advisory and gale warnings for the Outer Banks, with N.C. 12 on Ocracoke Island already experiencing some minor ocean overwash.
The coastal flood advisory is in effect from 9 p.m. tonight, Nov. 1, through 3 p.m. Monday. The National Weather Service Newport/Morehead City forecast office says one to two feet of inundation above ground level is expected in low-lying areas near shorelines and tidal waterways.
The N.C. Department of Transportation this morning reported some sand and ocean overwash on Ocracoke Island between the National Park Service Pony Pens and the ferry terminal. The road is currently open and passable.
Thunderstorms are expected this afternoon and evening with a slight risk of severe storms or isolated tornadoes, the weather service said. Much colder weather will follow the front, with a low of 43 expected for Nags Head overnight.
