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

A wind surge moving across the region will maintain choppy seas 

across the local waters through tonight. A weak surface high pressure

north of the region will promote light to moderate trade winds for 

the next several days. Therefore, seas will gradually improve during 

the end of the workweek and into the weekend.
