331 AM AST Sat Jun 28 2025

.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
Mariners can expect choppy seas across the local Atlantic and
Caribbean waters due to the surface high pressure across the
Atlantic, supporting a moderate to fresh easterly wind flow. A
tropical wave is expected to arrive by late Saturday night into
Sunday, increasing the potential for showers and thunderstorms across
the region. Another pulse with suspended Saharan Dust Particles will
follow the tropical wave from late Sunday night through at least
Tuesday.
