AMZ700-010830- 412 PM AST Tue Apr 30 2024 .SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS... A surface high pressure extending from the western to central Atlantic will tighten the local pressure gradient, promoting moderate to locally fresh trade winds across the Northeast Caribbean through at least tomorrow. As a result, expect hazardous seas for small craft operators due to confused seas associated with the increasing winds and a northeasterly swell spreading across the local waters. An induced surface trough, north of the islands, will weaken the pressure gradient and winds will shift from the east to east- southeast by the latter part of the week. $$ AMZ711-010830- Atlantic Waters of Puerto Rico and USVI from 10 NM to 19.5N- 412 PM AST Tue Apr 30 2024 ...SMALL CRAFT ADVISORY IN EFFECT THROUGH WEDNESDAY EVENING... .TONIGHT...Northeast winds 15 to 20 knots with gusts up to 30 knots.
