Years ago, when I was younger we had a Hurricane coming into the VA Beach area. We didn't take any chances and moved inland further. We adapted and reserved a spot at another campground and continued the vacation.
The best thing to do, is probably move and before the mandatory evacuations occur if that happens or there will be traffic like you wouldn't believe.
Good luck, it isn't that fun to cut the time short or change plans but, might be the safest.
