For the North Atlantic...Caribbean Sea and the Gulf of America:
Central Tropical Atlantic (AL92):
Showers and thunderstorms associated with a tropical wave located 
about 800 miles east of the Lesser Antilles have continued to 
become less organized. This system is moving into a region of 
increasing upper-level winds and dry air, and the possibility of 
development appears to be decreasing. Regardless of development, 
interests in the Lesser Antilles should continue to monitor the 
progress of this system since gusty winds and areas of heavy rain 
are possible across these islands Friday night and Saturday.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...medium...40 percent.
Eastern Tropical Atlantic (AL94):
A tropical wave located several hundred miles southwest of the Cabo 
Verde Islands is producing disorganized showers and thunderstorms. 
Environmental conditions are forecast to be generally conducive for 
gradual development, and a tropical depression could form late this 
week or this weekend while the wave moves westward or 
west-northwestward across the eastern and central tropical Atlantic.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...medium...50 percent.
