Puerto Rico and the U.S. Virgin Islands Waters

AMZ700-191400-
932 PM AST Wed Jun 18 2025

.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A persistent subtropical Atlantic ridge extending southward into the
northern Caribbean will continue promoting moderate to locally fresh
easterly winds, resulting in choppy seas, particularly over exposed
areas. Therefore, small craft should exercise caution across most
waters. Hazy skies will continue through at least late tonight,
slowly improving by the end of the week as the concentrations of
Saharan dust particles diminish. A tropical wave will move across the
Caribbean waters Thursday evening into Friday, likely leading to an
increase in showers and thunderstorm activity across that region.
