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

Light to moderate trade winds will prevail across the regional 

waters during the next few days. However, locally higher winds may 

result in choppy conditions across the Anegada Passage waters. A 

tropical wave is forecast to move across the regional waters and 

gradually deteriorate marine conditions during the latter part of 

the workweek. Shower and thunderstorm activity is also expected to 

increase with the passage of the wave.
