Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Sat Nov 22 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 0000 UTC surface analysis and satellite imagery through
0200 UTC.

...SPECIAL FEATURES...

Gale warning and large NW swell over the northern waters:
A 1005 mb low pressure is centered near 30N121W. A 1028 mb high
pressure is centered near 36N139W. The pressure gradient between
these features is supporting minimal gale force winds W of the
low. The low will shift further eastward while weakening
slightly. This will loosen the pressure gradient and diminish
winds below gale force overnight. This system has also ushered
in a large set of NW swell. Very rough seas greater than 12 ft
are currently N of 27N between 120W and 132W. These rough seas
will shift SE across the waters N of 25N and W of 117W through
Sat before subsiding below 12 ft. Seas will peak near 17 ft
tonight.

Hurricane Center at website-
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details.

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

The monsoon trough extends from 10N86W to 07N96W to 10N115W. The
ITCZ extends from 10N115W to 06N126W to 07N140W. Scattered
moderate convection is noted from 04N to 08N between 83W and 88W,
and from 04N to 06N between 127W and 135W.

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

Please see the Special Features section for details on a large
NW swell event.

A cold front is over the Baja California Norte waters with
moderate winds are over the waters west of Baja California Norte.
Moderate winds are also noted near the Revillagigedo Islands.
Light to gentle winds prevail elsewhere. Seas are in the 8-13 ft
range NW of Guadalupe Island. Seas are in the 6-8 ft range
elsewhere west of baja California Norte. Elsewhere, seas are in
the 4-6 ft range over the open waters off Mexico. Over the Gulf
of California, seas are 3 ft or less.

For the forecast, a secondary push of cold air accompanied by an
area of low pressure will quickly follow the cold front through
Sat night, generating fresh to strong NW to W winds with
scattered showers and isolated thunderstorms west of Baja
California Norte. Its associated front will usher in a set of
large NW swell, which will spread over the waters west of the
Baja California peninsula, and southward to the Revillagigedo
Islands through Mon before starting to subside. Fresh to strong N
gap winds can be expected over the Gulf of Tehuantepec from
early Sat to Sun night. Elsewhere, benign marine conditions are
expected.

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

Moderate to fresh winds are over and downstream the papagayo
region. Light to gentle winds are elsewhere. Seas are in the 3-6
ft range.

For the forecast, moderate to fresh NE to E winds are expected to
continue pulsing over and downstream of the Papagayo region into
early next week. Moderate or lighter winds are forecast
elsewhere during the forecast period.

...REMAINDER OF THE AREA...

Please see the Special Features section for details on a gale
warning and large NW swell event.

Aside from the winds and seas associated with a gale force low
in the northern waters, the pressure gradient between a 1028 mb
high pressure is centered near 36N139W and lower pressure in the
vicinity of the ITCZ is supporting fresh winds N of the ITCZ and
W of 125W. Large NW swell is propagating across the waters N of
20N, with seas in the 8-11 ft range W of a line from 20N135W to
30N117W. Seas of 8-10 ft are also over the waters N of the ITCZ
to 20N and W of 130W. Gentle to moderate winds, and seas of 4-7
ft, prevail over the remainder of the discussion waters.

The low will progress east southeastward through Sat then
dissipate Sun. Winds will diminish below gale force overnight,
with strong winds following the low pres as it moves into the
waters W of the Baja California Norte on Sat. Rough seas of 8 ft
or greater generated from this system will propagate across the
area, covering much of the discussion waters N of 08N and W of
115W this weekend before starting to slowly subside early next
week. Moderate to fresh trades will continue over the waters N of
the ITCZ to near 20N and W of 120W through the middle of next
week.
