Synopsis for the E Pacific within 250 nm of Mexico
1216 AM PDT Wed Aug 19 2026

.SYNOPSIS...Northerly gap winds will continue to pulse to strong
north winds over the Gulf of Tehuantepec each evening and night
through the end of the week. Seas will occasionally build to
rough during periods of strong winds. Low pressure across Baja
California will sustain a southerly wind flow across the Gulf of
California waters, with fresh to strong winds expected across
northern portions there through this evening before gradually
diminishing through the remainder of the week. Winds and seas
will diminish modestly across the Baja offshore waters through
the end of the week as high pressure weakens. Looking ahead,
winds and seas are expected to build across the outer offshore
waters of southwestern Mexico by Fri into the upcoming weekend in
association with a developing area of low pressure, expected to
develop outside of the offshore waters.
