For the North Atlantic...Caribbean Sea and the Gulf of America:
Northeastern Atlantic:
A strong non-tropical area of low pressure is located over the 
northeastern Atlantic several hundred miles west of the coast of 
Portugal. This system could acquire some subtropical or tropical 
characteristics tonight or on Sunday while it moves east- 
southeastward at 10 to 15 mph toward Portugal and northwestern 
Spain. The opportunity for tropical or subtropical development 
should end by Sunday night when the system encounters unfavorable 
environmental conditions. For more information, see High Seas 
Forecasts issued by Meteo France.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...20 percent.
Central Subtropical Atlantic:
Satellite imagery indicates that a broad area of low pressure has 
formed in association with the shower and thunderstorm activity a 
few hundred miles east-southeast of Bermuda. Additional slow 
development of this system is possible during the next few days as 
it drifts westward on Sunday and then accelerates northward early 
next week.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...low...30 percent.
Eastern Tropical Atlantic:
A tropical wave is expected to move off the west coast of Africa on 
Monday. An area of low pressure could form in association with the 
wave soon after it moves off the coast. Environmental conditions are 
marginally conducive for development, and a tropical depression 
could form by the middle to latter portions of next week while the 
system moves westward at 15 to 20 mph across the eastern and central 
tropical Atlantic.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...40 percent.
