NWS Marine Forecast


   AMZ700-012015-  336 AM AST Fri May 1 2026    .Synopsis for Puerto Rico and the U.S. Virgin Islands Waters...    A broad surface high over the central Atlantic interacting with  lower pressure and a weak trough near the region will maintain an  east to east-southeasterly flow across the local waters through the  weekend. Winds will increase from 5-15 knots today to 10-20 knots  with higher gusts through Saturday night and Sunday. Seas will  generally range from 3 to 5 feet, occasionally up to 6 feet, driven  by a combination of local wind waves and a small, long-period  northerly swell moving through the Atlantic waters and passages.  Scattered showers and isolated thunderstorms associated with the  nearby trough and moisture will continue at times, producing locally  higher winds and seas. Conditions will gradually improve early next  week as the pressure gradient relaxes and seas subside.    $$
