Puerto Rico and the U.S. Virgin Islands Waters

AMZ700-172030-
412 AM AST Tue Jun 17 2025

.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A persistent Atlantic subtropical ridge extending southward into the
northern Caribbean will continue to strengthen throughout the
period. This will lead to increasing moderate to locally fresh
easterly winds, resulting in choppy seas, particularly over exposed
areas. Therefore, small craft should exercise caution. A plume of
suspended Saharan dust is expected to linger through the workweek,
reducing visibility. A tropical wave will move across the Caribbean
waters on Thursday, likely leading to an increase in thunderstorm
activity across that region.
