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

A surface high pressure over the central Atlantic and a surface

induced low will promote a light to moderate northeast winds during 

the next few days. The local winds and a northerly swell will aid in 

generating choppy to hazardous seas across the Atlantic waters and

local passages through Tuesday. 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.
