AMZ700-020930- 416 PM AST Sun Nov 1 2026 .Synopsis for Puerto Rico and the U.S. Virgin Islands Waters... The interaction between a surface high over the Western Atlantic and a low pressure over the Central Caribbean will increase the local pressure gradient and steering wind flow, with moderate easterly winds and building seas between 3 and 5 feet, occasionally 6 feet, across the regional waters and passages through Monday and Tuesday. Wednesday onwards, a low pressure area is forecast to develop over the Western Atlantic, weakening the local pressure gradient and winds, leading to light to moderate south-southwesterly winds. Passing showers and isolated thunderstorms will continue across the regional waters over the next few days, with locally higher winds and seas near thunderstorms; small craft should exercise caution. $$ AMZ711-020930- Atlantic Waters of Puerto Rico and USVI from 10 NM to 19.5N- 416 PM AST Sun Nov 1 2026 .TONIGHT...East winds around 15 knots with gusts up to 25 knots.
