The link below is very interesting, it shows all September Cat 1 or 2 hurricanes that have been within 300 miles of Hanna's location. How many actually hit Fl? Of course every TC path is different and due to the differences in the enviroment during each time, my only point is that, just because a TC comes "close" to Florida certainly does not mean landfall in Fl. In fact one could argue that we here in NC have just a much chance of landfall from a storm in that area as anywhere, climatologically speaken.

With that said, looks as if Hanna has stalled or even attempting a kinda loop, she may be on verge of starting that northward motion.
