It could still miss the Florida coast entirely. Notice how the northern Florida penninsula is convex towards the West. If Frances takes a more northerly curve a miss is possible. This happened with Hurricane Floyd back in 1999. Back then a high pressure system caused a sharp turn to the north by Floyd. Perhaps similar forces will be at work here. Isn't there a high pressure system now developing over Florida that could block Frances?
Of course, anything could happen, but the safe money is on evacuating and preparation which is what we are doing.
Yes,there is a high pressure system which they showed to the east and if it weakens N FL gets the storm. Bad memory here so that could be backwards, there is a low to our north which is presently stalled according the local report just a little while ago.
I say it turns north goes to Martha's Vineyard and doodies all over the stuffy rich Democrats there....:)
