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

Surface high pressure over the western Atlantic will promote a light

to moderate east to northeast wind flow during the next few days. 

The local winds and a fading northerly swell will aid in generating 

choppy seas mainly across the offshore Atlantic waters, with more 

tranquil seas 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 period.
