UPDATE: It's Gustav. The storm brewing in the Caribbean today has reached tropical storm strength. Here is the latest advisory. The storm track is above. Here is the view from space. The earlier post follows:

Hurricane forecasters at the National Hurricane Center are now watching a new tropical depression - TD 7 - in the east-central Caribbean. It is showing signs of further organization, and could pose a threat from Jamaica to the Bahamas in a few days. Storm-battered Forida could also be in this storm's path.

The system is forecast to become a tropical storm later today or early tomorrow. Interests in Jamaica, eastern Cuba, and the southeastern Bahamas have been advised to pay attention to this system. Tropical storm warnings are already posted along the southern coast of Hispaniola.  An Air Force Reserve Hurricane Hunter aircraft was scheduled to investigate the storm and gather data this afternoon.

If this system reaches tropical storm status, with top sustained winds of 39 mph, it would be given the name Gustav, the seventh named storm of the 2008 Atlantic hurricane season.
