305 AM AST Sat Aug 2 2025

.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A surface high-pressure over the central Atlantic, combined with a
vigorous tropical wave, will promote moderate to locally fresh winds
through the weekend. Seas of up to 7 ft are likely for the offshore
Atlantic waters where a Small Craft Advisory is in effect through
this evening. The tropical wave will continue to affect the regional
waters today, with lingering effects expected into tomorrow,
increasing the frequency of showers and thunderstorms throughout the
weekend. Hazy skies due to the arrival of Saharan dust are
anticipated on Monday.
