Here's the current position of the low pressure system in the Caribbean, along with plots of the latest long range forecasts. The model guidance is tightly clustered (except for two outliers). The guidance suggests that the system will pass through Straits of Florida and enter the Gulf over the weekend. There is a strong likelihood that it could develop into a Hurricane before reaching the central Gulf Coast.
This will almost certainly result in an evacuation of the surface fleet at the Deepwater Horizon site, with orders likely coming today.

UPDATE: The National Hurricane Center is initiating coverage of the system as a Tropical Depression, with watches and warnings going up at 11:00 am EDT. New model outputs won't be available until later this afternoon.
