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

Moderate to locally fresh easterly winds will continue across the 

regional waters through the upcoming weekend. Moisture trailing a 

tropical wave will aid in the development of passing showers and 

possibly isolated thunderstorms over portions of the coastal waters 

during the rest of today. Seas will become choppy and hazardous into 

the upcoming weekend, due to the arrival of a long period swell which

will spread across the Atlantic waters and local passages.
