Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Tue Nov 25 2025

Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 140W. The following
information is based on satellite imagery, weather observations,
radar, and meteorological analysis.

Based on 1800 UTC surface analysis and satellite imagery through
2030 UTC.

...SPECIAL FEATURES...
Gulf of Tehuantepec Gale Warning: A cold front will move across
the Gulf of America through late Thu. Strong high pressure
building in the wake of the front will support fresh to strong
gap winds and rough seas across the Gulf of Tehuantepec tonight
and Wed. These winds will increase to gale force by early Thu as
teh front moves through southern Mexico followed by cooler and
drier air. A plume of fresh to strong N to NE gap winds and seas
of 8 to 10 ft will reach into Pacific waters up to 500 nm
downstream of the Gulf of Tehuantepec by late Thu. Winds and seas
will diminish Fri and Sat as the high pressure north of the area
shifts eastward.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

The monsoon trough extends from 06N77W to 09N87W to 08N115W. The
ITCZ extends from 08N115W to beyond 09N140W. Scattered moderate
convection is observed from 07N to 09N between 110W and 130W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

1029 mb high pressure is centered near 36N129W. Recent
scatterometer satellite passes indicated this pattern was
supporting moderate to fresh NW winds over the Gulf of
California, and moderate N to NE winds across the waters off Baja
California. Recent altimeter satellite passes showed combined
seas to 9 ft, primarily in NW swell. The scatterometer also
confirmed moderate to fresh winds in the Gulf of California and
off Cabo Corrientes. Light to gentle breezes are noted elsewhere.
Seas are 5 to 7 ft elsewhere over open waters, and 3 to 5 ft in
the Gulf of California.

For the forecast, fresh to strong winds will return in the Gulf of
Tehuantepec late tonight into early Wed, possibly increasing to
gale-force Thu morning through Fri morning leading to rough
seas. Fresh to strong winds will then persist in the Gulf of
Tehuantepec into early Sat before diminishing. Farther north, moderate
to fresh winds will pulse in the Gulf of California into mid-
week, briefly strong at times, then diminishing Thu. Large NW
swell off Baja California and the Revillagigedo Islands will
subside this evening. Looking ahead, a weak cold front or trough will
move into the waters off northern Baja California, supporting
moderate to fresh westerly gap winds across the northern Gulf of
California Sun night.

...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...

Fresh to locally strong NE winds are over the Papagayo region,
with moderate winds extending downstream to near 95W. Light to
gentle winds are elsewhere north of the monsoon trough. Gentle
to moderate winds are found south of the monsoon trough. Seas
are in the 3-5 ft range.

For the forecast, moderate to fresh NE winds will pulse over and
downstream of the Papagayo region this week and into next
weekend, locally strong at times. Moderate or lighter winds are
forecast elsewhere through the week and into next weekend. No
significant swells are forecast this week.

...REMAINDER OF THE AREA...

A ridge covering the area north of 15N and west of 115W is
supporting moderate to fresh NE trade winds from 10N to 20N west
of 115W. The trade winds are contributing to 8 to 10 ft combined
seas in this area, along with a component of longer-period NW
swell. NW swell of 8 to 9 ft lingers north of 20N and east of
120W toward the coast of Baja California. Gentle breezes and
moderate seas in a mix of swell are noted elsewhere.

The swell north of 20N and east of 120W will subside this
evening. The fresh trade winds and the remaining 8 to 10 ft seas
in the trade wind belt will gradually subside through late Wed as
the high pressure north of the area weakens. Looking ahead, a
new set of NW swell with rough seas may arrive by the end of the
week and into next weekend north of 25N. Moderate winds and seas
will persist elsewhere through Sun.
