NWS Marine Forecast


   AMZ700-302045-  404 AM AST Tue Dec 30 2025    .SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...    Surface winds will persist from the east for this morning becoming  more east-southeasterly as a frontal boundary approach to the  islands. This nearby frontal boundary will also increase the  potential for showers and thunderstorms, enhancing localized  hazardous marine conditions. Pulses of long- period northerly swell  will persist across the Atlantic waters and Caribbean passages  through the middle of the week. Therefore, small craft operators  should exercise caution, especially at exposed Atlantic waters.    $$
