For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
The National Hurricane Center is issuing advisories on Tropical Storm Gamma, located over the northwestern Caribbean Sea.
- A tropical wave is producing widespread cloudiness, showers, and thunderstorms over the eastern and central Caribbean Sea, with locally heavy rainfall and gusty winds affecting portions of the ABC Islands, the Lesser Antilles, the Virgin Islands, Puerto Rico, and portions of the coasts of Colombia and Venezuela. Environmental conditions are expected to become a little more conducive for development, and a tropical depression could form next week while the system moves westward or west-northwestward at about 15 mph across the central and western Caribbean Sea and then into the southern Gulf of Mexico.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...50 percent.
- A tropical wave located over the central tropical Atlantic is producing disorganized showers and thunderstorms. This system is expected to move toward the west-northwest or northwest at 10 to 15 mph, and some development is possible during the next couple of days before it encounters strong upper-level winds.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...20 percent.
- An area of disorganized showers and thunderstorms over the central Atlantic more than 1000 miles east-southeast of Bermuda is associated with a surface trough of low pressure. Some slow development of this system is possible during the next couple of days before it too encounters strong upper-level winds.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.
