Northeastern Atlantic:
A non-tropical area of low pressure has developed over the 
northeastern Atlantic several hundred miles north-northeast of the 
Azores. This system could acquire some subtropical or tropical 
characteristics on Saturday or early Sunday while it moves 
east-southeastward at 10 to 15 mph toward Portugal and northwestern 
Spain. The opportunity of tropical or subtropical development should 
end by Sunday night when the system moves into 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:
A weak area of low pressure located over the central subtropical 
Atlantic a few hundred miles east-southeast of Bermuda is producing 
an area of disorganized showers and thunderstorms. Development of 
this system, if any, is expected to be slow to occur while it drifts 
west-southwestward through Sunday and then turns northward early 
next week.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...20 percent.
