We are getting a lot of questions about the proximity of Gustav to Caribbean destinations - even Central American ones. It is important to note that the "Caribbean" is a large region. A big, powerful hurricane may only affect a small portion or a couple of the many major islands. The Gulf of Mexico is not the Caribbean, and the Gulf Coast of the US is not even close. Once a storm passes the "Caribbean" you can be pretty sure that no Caribbean islands are then in harms way.
The Bahamas is actually not the Caribbean either, but just a region of the Atlantic Ocean. Most storms, once they are close enough to garner TV and newspaper coverage (i.e. once the general public has heard of them), are on a pretty decided path (not always the case of course!). All you need to do is become a little familiar with the region to know whether a potential storm is going to be on a track that could spoil your vacation.
We are hearing a lot about Gustav because of the recent history of New Orleans with Katrina no doubt, and the heightened awareness is welcome. We should all be just as interested in Hanna, which could also make landfall on Georgia as a hurricane. This storm is currently in the area of the Turks and Caicos (moving away from - sort of on top of at the moment) and the Bahama Islands (moving towards). It is not much of a threat to the "Caribbean" outside of Hispaniola and Cuba.
