632 AM AST Tue Jul 29 2025

.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...

Trailing moisture from the tropical wave will continue to move
over the islands for the remainder of today. A surface high
pressure across the central Atlantic, combined with an induced
surface trough will continue to result in gentle to moderate east-
southeasterly winds. From midweek into the latter part of the
workweek, moderate to locally fresh east to southeasterly winds
are expected to return as a broad surface high pressure builds
over the far northeastern Atlantic.
