AMZ700-012045- 348 AM AST Wed May 1 2024 .SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS... A surface high pressure extending from the western to central Atlantic will maintain the local pressure gradient tight through today. As a result, expect hazardous seas for small craft operators due to confused seas associated with 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. $$ AMZ711-012045- Atlantic Waters of Puerto Rico and USVI from 10 NM to 19.5N- 348 AM AST Wed May 1 2024 ...SMALL CRAFT ADVISORY IN EFFECT THROUGH THIS EVENING... .TODAY...East winds 15 to 20 knots with gusts up to 25 knots.
