Whereas Katrina didn't lose much intensity because she went over the Everglades, Ophelia would likely come into "proper" Florida terrain. Yes, many storms that hit FL restrengthen in the gulf, but at least as many (if not more) make landfall in FL and never exit until they are spat back out into the Atlantic - and farther up the coast.

When there is low confidence in the path, there's no reason to discuss if she hits the GOM - she hasn't made any indication of hitting land yet. Look at the extrap - to become a GOM event, she'd have to go W or SW right now - ain't gonna happen (we hope)
