.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 across portions of the local

waters. 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.
