1008 AM AST Tue May 21 2024

.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
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 midweek. As the surface trough moves
closer to the region expect increasing shower and thunderstorm
activity across the local waters from Wednesday onward. This trough
may increase winds across the Mona Passage and Atlantic waters late
Wednesday night into Friday. Winds will slow down again by the
weekend.
