Puerto Rico and the U.S. Virgin Islands Waters

340 AM AST Thu Jul 3 2025

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

A broad surface high pressure over the central Atlantic will
continue to result in moderate to fresh easterly winds across the
region. Therefore, wind-driven seas will result in choppy marine
conditions across the Atlantic waters and the Caribbean Waters.
Saharan dust particles will be in place, resulting in hazy skies
and limited shower activity until Friday, when another tropical
wave moves into the islands, bringing showers and thunderstorms.
