861 FZPN27 KNHC 251559 OFFPZ7 Offshore Waters Forecast NWS National Hurricane Center Miami, FL 859 AM PDT Sun Jun 25 2023 Offshore Waters Forecast for the E Pacific within 250 nm of Mexico Seas given as significant wave height, which is the average height of the highest 1/3 of the waves. Individual waves may be more than twice the significant wave height. PMZ001-260400- Synopsis for the E Pacific within 250 nm of Mexico 859 AM PDT Sun Jun 25 2023 .SYNOPSIS...A broad surface ridge will dominate the offshore waters W of 100W through Mon night before weakening modestly. A tight pressure gradient between the ridge and a meandering trough over western Mexico will support pulsing fresh to strong winds from Cabo San Lazaro northward during this period. Gentle to moderate winds are expected elsewhere, except pulsing fresh southerly winds across the central Gulf of California during overnight hours beginning Mon. A broad area of low pressure is likely to form Mon through Tue offshore of southern Mexico. Environmental conditions appear conducive for development of this system, and a tropical depression is expected to form during the early to middle part of next week while it moves generally west-northwestward, parallel to the southwestern coast of Mexico. Gale-force winds are expected with this low on Wed and Thu across the offshore waters of West Central Mexico. $$ PMZ009-260400- Mexico Border S to 29N within 60 nm of shore- 859 AM PDT Sun Jun 25 2023 .TODAY...NW winds 15 to 20 kt.
