PMZ001-201945- Synopsis for the E Pacific within 250 nm of Mexico 1239 AM PDT Thu Mar 20 2025 .SYNOPSIS...High pressure building into eastern Mexico in the wake of a cold front will lead to gale force gap winds funneling through the Chivela Pass into the Gulf of Tehuantepec this morning into Fri. Seas may reach to around 20 ft by early Fri. Fresh winds offshore Baja California will gradually diminish through the end of the week. Fresh to strong winds in the central and southern Gulf of California will persist today due to a tight pressure gradient. Meanwhile, NW swell will spread toward the Revillagigedo Islands through tonight, with fresh swell from winds off southern California sustaining rough seas offshore Baja California Norte through Mon. Winds may pulse to fresh near Cabo Corrientes late this weekend. Looking ahead, fresh N winds may develop in the Gulf of Tehuantepec late Tue. $$ PMZ009-201945- Mexico Border S to 30N within 60 nm of shore- 1239 AM PDT Thu Mar 20 2025 .TODAY...NW winds 15 to 20 kt.
