428 PM AST Sat Apr 26 2025

.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
Light east to east-southeast winds will prevail through this evening
increasing to moderate tonight through early Sunday. A deep layer
trough will promote an unstable weather pattern across the local
waters. Thus, showers and thunderstorms are expected to develop from
now on, producing localized hazardous marine conditions. This
unstable and wet pattern will persist through at least next midweek.
A long-period northeasterly swell will spread across the Atlantic
waters tonight into Sunday, which could result in hazardous
conditions for small craft, mostly across the Atlantic waters.
