The interaction of an induced surface trough to the west and a weakening surface high pressure to the east will promote moderate east-southeast winds through today. As the surface trough moves closer to the region, expect increasing shower and thunderstorm activity across the local waters through early in the weekend. In addition, the proximity of an amplifying mid to upper level trough just west of the region will enhance thunderstorm development as well as increase winds and the potential for squally conditions across the Mona Passage and Atlantic waters late tonight through at least Friday. Winds are forecast to diminish once again by Friday night. $$ AMZ711-222115- Atlantic Waters of Puerto Rico and USVI from 10 NM to 19.5N- 415 AM AST Wed May 22 2024 .TODAY...Southeast winds 10 to 15 knots, becoming east 5 to 10 knots late.
