A broad surface high pressure over the central Atlantic will maintain moderate to fresh east to east-southeast winds and choppy to hazardous seas through the end of the workweek. Isolated thunderstorms are expected through this evening across the western waters of Puerto Rico due to a departing tropical wave. Another tropical wave will pass mainly south of the region on Thursday, increasing winds and showers across the Caribbean waters. Moderate to high concentrations of Saharan dust will continue to produce hazy skies and occasional visibility reductions. Small craft advisories are in effect through late Friday, due to a combination of 7 ft seas and 20 to 25 kt easterlies across both Atlantic and Caribbean waters, including the Mona Passage.. $$ AMZ711-090930- Atlantic Waters of Puerto Rico and USVI from 10 NM to 19.5N- 459 PM AST Wed Jul 8 2026 ...SMALL CRAFT ADVISORY IN EFFECT THROUGH FRIDAY EVENING... .TONIGHT...East winds 15 to 20 knots with gusts up to 30 knots.
