Synopsis for the E Pacific within 250 nm of Mexico
PMZ001
145 AM PDT Mon May 12 2025
Gale-force gap winds will persist across the Gulf of Tehuantepec through this morning, with a plume of rough seas reaching as far as 420 nm offshore. Winds and seas will diminish through tonight as high pressure north of the area weakens and shifts eastward. Farther north, a weak cold front will move into Baja California Norte by late Tue, then dissipate. High pressure building behind the front will enhance the NW winds to fresh conditions west of the Baja California peninsula through mid week, and large NW swell into Fri. Moderate or weaker winds and moderate seas, primarily in SW swell, will prevail elsewhere.
