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

A surface ridge north of the region and a tropical wave passing to

our south of the Mona Channel will combine to promote moderate to 

fresh trade winds across the regional waters for this weekend.

Overall, generally tranquil seas will prevail, except for a wind 

chop, which will be felt mainly over the offshore waters and local 

passages.
