Puerto Rico and the U.S. Virgin Islands Waters

AMZ700-242115-
404 AM AST Mon Nov 24 2025

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

High pressure building over the western Atlantic, combined with a
surface trough across the central Atlantic, will maintain gentle to
moderate east to northeast winds today. As the high pressure system
moves into the central Atlantic through mid-week, the pressure
gradient will tighten, promoting moderate to locally fresh trade
winds from tonight or Tuesday onward. As a result, expect confused
seas caused by a mix of locally choppy conditions and a brief long-
period northeasterly swell arriving between Tuesday and Wednesday.
Small craft operators will likely need to exercise caution,
particularly across the offshore waters and local Caribbean passages
for most of the forecast period.
