A tropical depression in the Gulf of Mexico is expected to strengthen into a tropical storm named Danielle as it moves toward the site of the oil spill off Louisiana's coast.
The depression had maximum sustained winds near 35 mph early Wednesday but is expected to reach tropical storm strength of 39 mph later in the day or Wednesday night.
Tropical Storm warnings have been issued.
BP and Coast Guard officials have halted drilling on a relief well intended to permanently plug the blown-out oil well in the Gulf.
