1037 AM AST Tue May 13 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 Caribbean waters and the Mona Passage through
at least tonight due to seas building up to 7 feet. Small Craft
Should Exercise Caution over most of the other waters. Thunderstorm
activity is likely across the regional waters, especially late in the
workweek and into the weekend, resulting in locally higher winds and
seas.
