For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

1. Showers and thunderstorms have become more concentrated near the 
center of a gale-force low pressure system located over the central 
Atlantic several hundred miles southeast of Cape Race, Newfoundland. 
The low continues to lose its frontal structure, and the system is 
likely to transition to a subtropical storm later tonight or on 
Sunday while it moves southeastward over the central subtropical 
Atlantic.  By the middle of next week, the system is expected to 
turn northward and move toward colder waters.  For more information 
on this system, including gale warnings, see High Seas Forecasts 
issued by the National Weather Service. 
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

2. A broad area of low pressure located over the tropical eastern 
Atlantic a few hundred miles south of the Cabo Verde Islands is 
producing a large area of disorganized showers and thunderstorms. 
Slow development of this system is possible during the next couple 
of days before it moves into a region of strong upper-level winds 
early next week.  This system is expected to move west-northwestward 
to northwestward at 10 to 15 mph during the next few days.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...low...30 percent.
