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

Moderate east to southeast trade winds will continue through the 

rest of the weekend. A small northeasterly swell will move across 

the Atlantic waters from Sunday to Monday. Winds are expected to 

increase next week as a surface high pressure builds across the 

western Atlantic and Tropical Storm Eta strengthens southeast of 

Florida. This will promote choppy to hazardous seas once again across

the regional waters. Periods of shower and isolated thunderstorm 

activity can be expected across portions of the regional waters 

through the middle of next week.
