I looked at that link you posted....it's pretty spooky. I really don't know much about these things so any opinion i have would be way off, but i'll give it a try. Seems like they are going a little extreme with it on that map...there would have to be some pretty strong steering currents (you'd think) for the storm to go wnw and suddenly turn the opposite direction. I could see it going more to the west, like towards east coast of fla and perhaps georgia, but not sw into the caribbean.

Then again, stranger things have happened with other storms like Jeanne and i remember another storm looping around again, cant remember what the name is though.
