NWS Marine Forecast


   AMZ700-110830-  402 PM AST Tue Mar 10 2026    .SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...  A broad surface high pressure system across the Atlantic will  promote moderate to fresh easterly winds, keeping seas 6 to 7 feet  across the offshore Atlantic waters. Therefore, a Small Craft  Advisory will remain in effect for that zone through at least  Wednesday morning. Across the nearshore and coastal waters, seas will  remain between 5 and 6 feet, resulting in choppy marine conditions.  Small craft operators are urged to exercise caution. Improving marine  conditions are forecast for Thursday and Friday, as winds are  expected to subside to gentle to moderate and seas decrease to  between 3 and 5 feet. However, winds are forecast to increase again  around Saturday night into Sunday, leading to a deterioration in  marine conditions once again.    $$
