I don't think it's going that far north. Latest movement has more of a westward motion - right at Miami. It's going to have to start turning north very soon if that central Florida track is to hold up.
Those models bring Frances in between Melbourne and West Palm Beach... that's exactly where the Hurricane Center has now moved the target area.
Figure on a strike in that area near HIGH TIDE Saturday morning -- Noon Saturday -- Melbourne has a high tide around 11:20am.
