417 AM AST Wed May 14 2025

.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A broad surface high pressure over the Central Atlantic will promote
breezy easterly winds that will result in choppy conditions across
the offshore waters. A Small Craft Advisory is in effect for the
Offshore Atlantic and Anegada Passage through at least this evening
due to seas building up to 6 to 7 feet. Small Craft Should Exercise
Caution over most of the other local waters. A deep trough will
promote an unsettled weather pattern with a high chance for
thunderstorm development from Thursday afternoon onward, resulting in
locally higher winds and seas.
