Katrina is going to wobble across the state in a general westward motion with the occasional southward drop. It's inland now and will remain that way; theoretically, if it wobbles southwest and then back northwest as it nears the west coast as some of the guidance suggests, it could stay over land for a longer period of time than expected...albeit that's a matter of just a couple of hours. The short-term track will have little impact on the second landfall location; it's still a timing issue.

Note that the inner-core wind field of the storm will not weaken all that much over the Everglades, very wet and very warm right now, but that the strongest winds with this storm for the next day or so will be located along the east coast & over open waters. This is a scenario similar to Frances last year. Frances took about a day to cross the state; given a slower motion here but less land to cross, a similar evolution seems likely with this one.
