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

Light to moderate trade winds will prevail across most of the 

regional waters during the next few days. However, locally higher 

winds may result in choppy conditions, especially in the nearshore 

waters of northern Puerto Rico. A tropical wave is forecast to move 

across the area, leading to gradually deteriorating marine conditions

during the latter part of the workweek. Shower and thunderstorm 

activity is also expected to increase with the passage of the wave.
