Puerto Rico and the U.S. Virgin Islands Waters

101 PM AST Fri Nov 28 2025

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

An upper-level trough leaving the Northeast Caribbean will promote a
slight risk of thunderstorm formation over local waters, especially
during the afternoon and evening hours. A surface high pressure over
the Central Atlantic, interacting with a cold front moving eastward
across the western Atlantic, will promote moderate to fresh
easterlies winds today, becoming fresh to strong trade winds this
weekend into early next week. This will result in rough to hazardous
seas across the local waters today and throughout the weekend.
