A cold front across the western Atlantic will continue to approach the northeastern Caribbean during the next few days. A broad surface high pressure will remain anchored over the central Atlantic promoting light to moderate east to southeast winds through the weekend. However, another surface high pressure will build over the western Atlantic and push the front over the local area by early next week. This will promote moderate to fresh northeast winds from Monday night onwards. Shower and thunderstorm activity will gradually increase each day, and mainly across the Atlantic waters and the Mona Passage. $$ AMZ711-120815- Atlantic Waters of Puerto Rico and USVI from 10 NM to 19.5N- 354 PM AST Fri Apr 11 2025 .TONIGHT...East winds 10 to 15 knots with gusts up to 20 knots.
