Synopsis for the E Pacific within 250 nm of Mexico
752 AM PDT Wed Mar 18 2026
.SYNOPSIS...The pressure gradient between high pressure across
eastern Mexico and the equatorial trough will support gale-force
gap winds and very rough seas in the Tehuantepec region through
this morning before diminishing slightly, then will pulse again
to gale-force late tonight through at least the end of the week.
Elsewhere, mainly light to gentle winds will prevail, increasing
to moderate near Baja California by the end of the week, then to
moderate to fresh this weekend as the pressure gradient tightens
slightly. Moderate seas will continue to prevail over the open
waters, with slight seas in the Gulf of California. Looking
ahead, seas may build in fresh N swells off Baja California Norte
late in the weekend.
