Just to further echo Jet Stream Rider's post.
I was in Cary, NC for Fran (c1996) and without power for 5 days plus had three trees on my house. This path, if to be believed, will rock not only the coastal plan but a great deal of the piedmont as well. I would take the initial steps for preparedness starting no later than Monday. It's projected landfall timetable has now raced ahead 12hrs. With Fran I was already without power when the eye came ashore 120 miles away.
