Puerto Rico and the U.S. Virgin Islands Waters

AMZ700-222015-
310 AM AST Sat Nov 22 2025

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

High pressure over the western Atlantic and a surface trough across
the central Atlantic will maintain moderate trade winds through the
weekend. By Sunday and Monday, a surface low and its cold front will
interact with the high pressure, weakening the local pressure
gradient and producing gentle to moderate easterly winds. Another
high pressure will then build over the western Atlantic and move into
the central Atlantic from Monday through Thursday. This will tighten
the pressure gradient again, supporting moderate to fresh trade winds
and choppy seas from Tuesday into mid-week. Thus, expect confused
seas due to locally choppy conditions combined with a long-period
northeasterly swell arriving between Tuesday and Wednesday.
