The surface high pressure north of the region will continue to gradually shift east over the coming days. While some fluctuations in the wind pattern are expected, winds will generally remain from the east to east-southeast through the period, gentle to moderate through Tuesday, then increasing to moderate to locally fresh by Tuesday night across the regional waters. As winds increase, seas will become choppy, especially in exposed areas. 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 from tonight into early in the week. $$ AMZ711-160915- Atlantic Waters of Puerto Rico and USVI from 10 NM to 19.5N- 439 PM AST Sun Jun 15 2025 .TONIGHT...East winds 10 to 15 knots with gusts up to 25 knots.
