For the North Atlantic…Caribbean Sea and the Gulf of Mexico:
1. A large area of showers and thunderstorms was located along a sharp surface trough from near eastern Cuba through the southeastern Bahamas into the southwestern Atlantic. Conditions are forecast to become more favorable for development late this week, and a tropical depression could form near the northwestern Bahamas or South Florida as early as Friday. Further development is possible over the eastern Gulf of Mexico later this weekend. The disturbance will likely produce periods of locally heavy rainfall and gusty winds across the Bahamas through Friday, and across Florida during the weekend.
* Formation chance through 48 hours…medium…40 percent.
* Formation chance through 5 days…medium…60 percent.
2. A broad low pressure system, associated with a tropical wave, was located about 500 miles east of the Lesser Antilles. This disturbance is accompanied by a few thunderstorms showing little organization. The system is forecast to move westward where upper-level winds will become even less favorable for tropical cyclone formation.
* Formation chance through 48 hours…low…10 percent.
* Formation chance through 5 days…low…10 percent.
3. A tropical wave located in the far eastern Atlantic Ocean near the Cabo Verde Islands is forecast to move quickly westward during the next several days. Environmental conditions may become more favorable for development as the system approaches the Lesser Antilles from late this weekend into early next week.
* Formation chance through 48 hours…low…near 0 percent.
* Formation chance through 5 days…low…30 percent.
