.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 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.
