Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Mon Dec 1 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 0600 UTC surface analysis and satellite imagery through
0920 UTC.

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

The monsoon trough extends from 09N84W to 08N89W to 06N93W. The
ITCZ stretches from 06N93W to 06N107W to 12N114W then resumes
from 09N128W and beyond 09N140W. Scattered moderate convection
is from 04N to 10N E of 100W, and from 06N to 13N W of 134W.

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

Northeast winds associated with a surface trough near the Yucatan
Peninsula is funneling through the Chivela Pass and causing
fresh to strong gap winds in the Gulf of Tehuantepec this
morning. A surface trough to the SW of the Revillagigedo Islands
continues to generate heavy showers and thunderstorms mainly
from 14N to 22N between 110W and 116W with scattered showers
extending NE to the mouth of the Gulf of California. Fresh to
strong NE winds are occurring in the mouth of the Gulf of
California. Otherwise, a weak pressure gradient support light to
gentle winds and moderate seas elsewhere, except for slight seas
in the Gulf of California.

For the forecast, fresh to strong N to NE winds in the Gulf of
Tehuantepec will continue this morning and pulse again late Tue
into Wed morning. A trough just SW of the Revillagigedo Islands
will meander near the islands through Tue, bringing showers and
thunderstorms and possibly locally strong winds and rough seas.
Looking ahead, moderate long-period NW swell will reach the Baja
California Norte offshore waters Tue, then subside Thu.
Otherwise, moderate to fresh N winds will pulse in the northern
Gulf of California through Fri night.

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

Surface ridging extending across the northern Caribbean supports
moderate to fresh NE winds in the Gulf of Papagayo. South of the
monsoon trough and between Ecuador and the Galapagos Islands,
winds are gentle to moderate from the S to SW. Elsewhere, light
to gentle winds prevail along with moderate seas.

For the forecast, fresh gap winds will pulse nightly this week
in the Papagayo region. Moderate or lighter winds and moderate
seas are expected elsewhere through Fri night.

...REMAINDER OF THE AREA...

Weak low pressure of 1016 mb is near 26N135W with a weak cold
front trailing from this low to 23N132W over to 22N140W. Only
moderate to locally fresh winds accompany and follow the front
and low, and associated swell is supporting 8 to 11 ft seas N of
23N and W of 134W. A surface trough to the SW of the Revillagigedo
Islands continues to generate heavy showers and thunderstorms
mainly from 14N to 22N between 110W and 116W with scattered
showers extending NE to the mouth of the Gulf of California.
With this convection strong to gusty winds and rough seas are
likely. The rest of the tropical eastern Pacific is under the
influence of modest ridging, leaving winds mainly gentle, and
seas moderate.

For the forecast, the weak cold front in NW waters will drift S
through today, then dissipate. Large NW swell will continue to
spread southeastward across the NW subtropical and tropical
waters today with seas peaking around 12 ft. Rough seas will
reach E to 122W and S to 10N Tue and Tue night, before decaying
into late week.
