SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS
Light to moderate trade winds will continue to increase, generated by a surface high-pressure ridge across the central and eastern Atlantic. By tomorrow, a stronger high-pressure ridge will build and spread over the western Atlantic. Consequently winds will increase, becoming fresh to locally strong. Hazardous seas for small craft are likely due to a long period northwest to north swell and increasing wind speeds from tomorrow into early next week. Additionally, increased shower activity is possible as remnants of a cold front approach the regional waters.
