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

A broad surface high pressure extending across the region from the 

north- central Atlantic and a tropical wave now moving south of 

Hispaniola will aid in generating moderate to locally fresh east 

southeast winds today. Choppy seas are expected across the offshore 

Caribbean waters and the Mona Passage at least until later tonight. 

Winds and seas will then gradually diminish and subside into early 

this week. Showers and isolated thunderstorm activity is expected

over the regional waters today, with periods of locally heavy 

rain and gusty winds and frequent lightning.
