If it's just a tropical storm going through Florida, it's not that bad. Ernesto is very chewed up now, and the air betweeen it and Florida is pretty dry. It'll be hard for it to get up to hurricane strength.
dead on Miami hit??
As battered as it is and with the hostile environment it has to traverse, I have to wonder if it'll even survive its trip over Florida to emerge into the Atlantic. OTOH, if it does make it to the Atlantic, it's got the Gulf Stream to feed on.
