For the North Atlantic...Caribbean Sea and the Gulf of America:
Updated for the Central Atlantic Sub-Tropical System.
Central Tropical Atlantic (AL92):
An area of showers and thunderstorms associated with a tropical wave 
is located about 900 miles west-southwest of the Cabo Verde 
Islands. Environmental conditions are forecast to be conducive for 
development during the next couple of days, and a tropical 
depression will likely form while the system moves westward to 
west-northwestward across the central tropical Atlantic.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 7 days...high...80 percent.
Central Subtropical Atlantic (AL93):
Recent satellite wind data indicate that the circulation 
associated with the low pressure area located about 1050 miles 
east-northeast of Bermuda has become better defined and the 
system is producing tropical-storm-force winds to the southeast of 
the center.  The system is likely to become a short-lived tropical 
storm while it moves eastward to east-northeastward at around 20 mph 
across the central subtropical Atlantic. Addition information on 
this system is found in High Seas Forecasts issued by the National 
Weather Service.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 7 days...high...80 percent.
Eastern Tropical Atlantic:
A tropical wave just offshore of the coast of west Africa is 
producing disorganized showers and thunderstorms. Environmental 
conditions are forecast to be generally conducive for some 
development of this system during the next several days while it 
moves westward or west-northwestward across the eastern and central 
tropical Atlantic.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...30 percent.
