.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...

A surface high across the north-central Atlantic will generate fresh

to locally strong east-southeast winds today, gradually decreasing 

during the weekend into early next week. This will cause choppy to 

hazardous seas across the local waters. Shower and thunderstorm 

activity is expected with the passage of patches of surface moisture,

followed by a tropical wave, along with favorable conditions aloft.
