Individual waves may be more than twice the significant wave height. PMZ001-190345- Synopsis for the E Pacific within 250 nm of Mexico 842 AM PDT Tue Mar 18 2025 .SYNOPSIS...Gale-force northerly gap winds are diminishing in the Gulf of Tehuantepec, but will return Thu morning through Fri morning. Associated rough seas will subside there and downstream through tonight, with seas building up to around 20 ft with the next event. Otherwise, the cold front over the NW waters will track southeastward while gradually dissipating. Fresh to strong winds behind the front offshore Baja California will continue into early Wed before diminishing, while they spread south across the central and southern Gulf of California, lingering through Thu due to a tight pressure gradient. Fresh to strong NW to N winds may pulse again offshore Baja California north of Cabo San Lazaro through the end of the week. Meanwhile, the NW swell will spread southeastward through mid-week, with fresh swell from winds off southern California sustaining rough seas through the end of the week into the weekend. $$ PMZ009-190345- Mexico Border S to 30N within 60 nm of shore- 842 AM PDT Tue Mar 18 2025 .TODAY...NW to N winds 20 to 25 kt.
