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

A surface induced trough will generate a moderate east to northeast

surface wind flow, resulting relatively tranquil marine conditions.

However, locally higher winds will generate choppy seas, 

particularly over the waters of western Puerto Rico. Increased shower

and thunderstorm activity is expected with the passage of the 

trough.
