It definitely looks like a broadside to the Carolinas. I don't know all the models but the ukmet global modelling system has a tendency to be the most solid... and it sure looks like a direct landfall.
We had some experience here with blocking lows or highs, they can get you stuck in a weather pattern that just won't go away... It could even be worse if the storm does hook northward trying to push up the coast with that big high slowing it down. Slow moving hurricanes can dump the motherload of rain. At least with a broadside landfall Florence will quickly lose steam over land. I'm sure that's small consolation to those in the area though!
Time to batten your hatches for Wednesday...
