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

A surface high pressure over the central Atlantic will promote a 

light to moderate northeast winds during the next few days. The local

winds and a northerly swell will aid in generating hazardous seas 

mainly across the offshore Atlantic waters through at least late 

tonight. More tranquil seas are forecast elsewhere through at least 

midweek. Periods of isolated to scattered showers can be expected to 

affect mainly portions of the Atlantic waters and local passages 

during the forecast period.
