A 280 track takes Frances right into the Keys. The keys is still very much in play.
I'm hedging bets it's going to hit Palm Beach or come further S. closer to the Miami area. The problem with this storm is how big it is. If it hits Miami head-on (pray that does not happen) the Keys will get winds/storms but only the upper Keys will face hurricane force winds which are extending out 84 from center last I saw.
In all seriousness and honesty, nobody knows where this damned thing is going to hit, only possibilities. From the Southern tip of Florida on up needs to be prepared for this one.
