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

Moderate to fresh east to northeast trade winds will prevail. Seas

into early next week. This along with increasing trade winds will 

result in choppy and very hazardous seas through the upcoming weekend

across much of the local waters and passages.
