Nothing that would prevent it, but a ton of things that make it unlikely. Not the least of which is that it likely won't make it here as a storm, but even if it did, the weather to our north and west (cold fronts and such) as well as the strength and orientation of the tropical ridges that existed with Charley will certainly have changed a great deal. I don't see Earl as a significant threat to Tampa or, thank God, to Orlando or the devestated SW coast of Florida. Having said that, it always pays to keep an eye on tropical systems, as you should never forget, nothing, absolutely nothing PREVENTS a repeat, just odds and circumstance make it unlikely.
