Cape Lookout seashore is only accessible by boat, no roads or bridges. It is only smart to get campers off of there now. Non-residents have been ordered to evacuate Ocracoke Island. Another good call, since there are only two ways out: 3-1/2 hour ferry ride to Cedar Island or Swan Quarter, then a long drive to get far enough inland, or a 1/2 hour ferry to Hatteras, then a drive all the way up the Outer Banks to Nags Head before you can get to the mainland.
I'd ride out a Cat 4 in the lighthouse at Cape Lookout. Cat 5 might get a bit dicey, but I don't think it would take down the lighthouse.
