335 AM AST Tue Sep 2 2025

.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A surface high pressure over the central Atlantic and a surface
trough will continue to result in moderate to locally fresh east to
southeasterly winds across the local waters, producing moderate chops
to localized choppy seas. Seas will remain up to 5 feet across the
Atlantic offshore waters and even lower across the coastal waters.
For the upcoming weekend, the arrival of a tropical wave is expected
to increase the frequency of showers and thunderstorms, potentially
resulting in localized hazardous marine conditions.
