The thing about evacuating the southern NC beach area is you either go north or south on divided Hwy 17....
Or you try and go inland. Inland routs are all two lane country roads through small towns.
Hwy 211 out of Supply (on Hwy 17) is 25 miles and two lane through the Green Swamp which is most pine trees. One tree can block the road.
I’m on Ocracoke right now. Very unsettling
Coastal dwellers should head W/SW. Get an early start.
