The surface high pressure northeast of the region will continue to gradually shift east over the coming days. While some fluctuations in the wind pattern are expected, moderate to locally fresh winds from the east to east-southeast will promote choppy conditions mainly over exposed areas, small craft should exercise caution. A plume of suspended Saharan dust is expected to linger through midweek, potentially causing a slight reduction in visibility. Meanwhile, increasing moisture and instability associated with an upper-level trough will likely lead to a rise in thunderstorm activity. $$ AMZ711-171000- Atlantic Waters of Puerto Rico and USVI from 10 NM to 19.5N- 436 PM AST Mon Jun 16 2025 ...SMALL CRAFT SHOULD EXERCISE CAUTION... .TONIGHT...East winds 15 to 20 knots with gusts up to 30 knots.
