Tropical Weather Discussion

2205 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 1800 UTC surface analysis and satellite imagery through
2030 UTC.

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

The monsoon trough extends from 09N84W to 07N104W. The ITCZ runs
from 07N104W to 10N115W, then resumes from 09N126W to beyond
08N140W. Scattered moderate convection noted from 07N to 13N E of
98W and from 07N to 10N W of 130W.

...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 Socorro Island.
Moderate E winds are also present in this area. Fresh gap winds
are noted in the Gulf of Tehuantepec . Elsewhere, gentle winds
dominate N of 18N, with light and variable winds to the south.
Seas are moderate, except slight S of 18N and in the Gulf of
California.

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

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

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 locally
moderate S to SW winds and 4 to 6 ft seas exist. Elsewhere,
mainly winds with 3 to 5 ft seas in slight swells prevail.

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

...REMAINDER OF THE AREA...

A mid-level trough is noted from 23N121W to 19N124W, inducing
scattered moderate convection from 19N to 22N between 122W and
126W. A surface trough farther SE extends from just SW of
Socorro Island to 12N120W, and is producing scattered moderate
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. A weak trough has also slide southward of 30N, and
extends from 30N123W to 27N128W to 30N131W.

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. A zone of moderate NE
winds and rough seas, in primarily NW swell, is noted W of 125W
and N of 10N.

For the forecast, large NW swell will cause rough seas to persist
tonight W of 120W and N of 09N, then gradually decay through Wed.
Thereafter, moderate seas will prevail into the weekend. Moderate
to fresh trades will dominate N of the ITCZ to 20N and W of 120W
through the week, with moderate or weaker winds elsewhere.
