Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Tue Dec 2 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.

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

The monsoon trough extends from 09N84W to 07N107W. The ITCZ runs
from 07N107W to 12N117W, then resumes from 08N128W to beyond
08N140W. Scattered moderate convection is seen up to 120 nm along
either side of the monsoon trough E of 100W.

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

A surface trough SW of the Revillagigedo Islands is aiding in
scattered moderate convection in the vicinity of the islands.
Moderate E winds are also present in this area. Moderate gap
winds are noted in the Gulf of Tehuantepec and the northern Gulf
of California. Elsewhere, light to gentle winds prevail.
Moderate seas dominate, except slight seas are present in the
Gulf of California.

For the forecast, fresh N winds in the Gulf of Tehuantepec will
pulse to strong tonight, then subside to gentle Wed. A surface
trough just southwest of the Revillagigedo Islands will keep
thunderstorms near the islands through at least Wed night.
Moderate to fresh N winds will pulse in the northern Gulf of
California through Thu night.

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

Refer to the Monsoon Trough/ITCZ section for convection in the
region. Surface ridging extending across the northern Caribbean
Sea supports moderate to fresh NE winds and 4 to 6 ft seas in
the Gulf of Papagayo. S of the monsoon trough, gentle to
moderate S to SW winds and 4 to 6 ft seas exist. Elsewhere,
light to gentle winds with 3 to 5 ft seas in light to moderate
swells prevail.

For the forecast, moderate to fresh gap winds will persist near
the Papagayo region through Thu. Moderate or lighter winds and
moderate seas are expected elsewhere through the weekend.

...REMAINDER OF THE AREA...

A dissipating cold front is noted from 20N137W to beyond 20N140W.
Fresh E winds are N of this front, extending to 25N. A surface
trough is noted from 23N121W to 19N124W, inducing scattered
moderate convection from 19N to 22N between 122W and 126W.
Another surface trough farther SE extends from just SW of
Socorro Island to 11N120W, and is producing scattered moderate
to isolated strong convection from 17N to 20N between 112W to
118W. N of this trough, a corridor of fresh winds extends from
18N to 22N between 113W and 123W. Refer to the Monsoon
Trough/ITCZ section for additional convection in the region.

Broad and relatively weak ridging extending south from a 1028 mb
high pressure centered off Oregon is supporting mainly gentle
winds across the basin, with moderate seas. However, slowly
decaying NW swell is leading to rough seas W of 125W and N of
10N.

For the forecast, large NW swell will continue to spread
southeastward across the northwestern subtropical and tropical
waters while weakening through Wed. Rough seas will reach east to
120W and south to 09N tonight, then slowly decay to moderate into
late week.
