Synopsis for the E Pacific within 250 nm of Mexico
918 AM PDT Wed Mar 12 2025

.SYNOPSIS...Rough seas of 8 to 11 ft will propagate
southeastward through the waters offshore of Baja California
today. A cold front will push into the Baja California Norte
waters early on Thu, producing fresh SW winds ahead of the front,
and fresh to locally strong NW winds behind the front through
late Thu morning. Fresh to strong SW winds are expected in the
northern Gulf of California this evening ahead of the front, with
strong to near-gale force W to NW winds in the wake of the front
Thu into early Fri. N swell associated with the cold front will
reinforce rough seas offshore of Baja California Norte by Thu
afternoon, with rough seas spreading through all waters offshore
of the peninsula through Fri. Peak seas of 12 to 14 ft are
anticipated north of 27N and west of 117W Thu evening through
Fri. Elsewhere, pulsing moderate to locally fresh N to NW winds
will prevail offshore of western Mexico through Fri, before more
widespread fresh to locally strong winds develop Fri afternoon as
the aforementioned cold front moves southeastward through the
region. Looking ahead, gale force winds will be possible in the
Gulf of Tehuantepec Sun night through early next week.
