A tropical depression has formed in the Bahamas.
The system is currently moving in direction of the massive Gulf oil spill.
Ship crews are preparing to evacuate the area around the broken BP well site in the Gulf of Mexico as the tropical rainstorm brews in the Caribbean.
If the storm threatens, the cap that has been keeping the oil bottled up since last week may have to be reopened, allowing crude to gush into the sea again.
Coast Guard Adm. Thad Allen, the government's point man on the crisis, says it's "going to be a judgment call."
Forecasters say the storm system will probably move into the Gulf over the weekend.
Even if the storm does not hit the area directly, it could affect the effort to contain the oil and clean it up for weeks, just as Hurricane Alex did.
