Thanks for the new thread mike.
CAT 5 Ivan is going to bottom out at about 890 mb's, nothing seems like it will hinder it's devlopment, except some dry air coming off Cuba's moutains but Ivan's near perfect outflow will take care of that. Those peole in the Caymans Islands and the Western tip of Cuba are in for a rude awakening, as this hurricane might hit as a CAT 5. Luckily though, the keys and the other areas that have already been hit with two major hurricanes seem like they will be spared if that ridge holds out. Lets hope for the best.
