As a surface trough approaches the CWA, winds will briefly gentle to moderate by Tuesday night, becoming moderate from the east late Wednesday night. $$ AMZ711-011215- Atlantic Waters of Puerto Rico and USVI from 10 NM to 19.5N- 738 PM AST Sun Nov 30 2025 ...SMALL CRAFT ADVISORY IN EFFECT UNTIL 6 AM AST MONDAY... .REST OF TONIGHT...East winds around 15 knots with gusts up to 25 knots.
