160 FZPN27 KNHC 201550 OFFPZ7 Offshore Waters Forecast NWS National Hurricane Center Miami, FL 850 AM PDT Thu Mar 20 2025 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. PMZ001-210400- Synopsis for the E Pacific within 250 nm of Mexico 850 AM PDT Thu Mar 20 2025 .SYNOPSIS...High pressure ridging surging southward across eastern Mexico in the wake of a cold front has initiated gale- force gap winds through the Chivela Pass and into the Gulf of Tehuantepec this morning. Guidance suggests that winds may peak to 40 kt, or slighter higher tonight. The culprit tight pressure gradient is forecast to slacken by Fri afternoon allowing for these winds to diminish to fresh to strong speeds. Fresh to strong winds in the central and southern Gulf of California will persist today due to a tight pressure gradient. Meanwhile, northwest 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 north winds may develop in the Gulf of Tehuantepec late Tue. $$ PMZ009-210400- Mexico Border S to 30N within 60 nm of shore- 850 AM PDT Thu Mar 20 2025 .TODAY...NW winds 15 to 20 kt.
