Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Sat Nov 29 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
2135 UTC.

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

The monsoon trough extends from 08N83W to 05N94W to 10N120W to
09N129W. The ITCZ stretches from 09N129W to beyond 08N140W.
Scattered moderate to isolated strong convection is observed from
07N to 20N and between 105W and 122W.

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

A 1035 mb high pressure system over the eastern United States
supports fresh to strong northerly winds and seas of 6-8 ft
across the Gulf of Tehuantepec. A recent scatterometer satellite
pass captured a large area of 20-25 kt winds, including
downstream to 11N. The remainder of the basin is under a weaker
pressure gradient, allowing for primarily moderate northerly winds
and moderate seas from 17N to 24N, affecting the offshore waters
of SW Mexico. Elsewhere, light to gentle winds and slight to
moderate seas prevail.

For the forecast, strong winds will persist in the Gulf of
Tehuantepec, diminishing to fresh speeds this evening. Strong
speeds winds will briefly resume in Tehuantepec Sun night into
Mon, and then again Tue night into Wed. Otherwise, a surface
trough is developing SW of the Baja California Sur offshore
waters and then will drift NE, impacting the waters near the
Revillagigedo Islands with moderate to fresh NE to E winds Sun
into Mon. Looking ahead, a series of long-period NW swell will
reach the Baja California Norte offshore waters midweek.

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

High pressure north of the Caribbean supports moderate to fresh
easterly trade winds and moderate seas in the Gulf of Papagayo.
Meanwhile, south of the monsoon trough and between Ecuador and
the Galapagos Islands, winds are gentle to moderate from the S to
SW and seas are moderate to 5 ft. Elsewhere, light to gentle
winds and slight to moderate seas prevail.

For the forecast, fresh NE winds and moderate seas will prevail
in the Papagayo region through Sun, and resume again Wed night.
Moderate or lighter winds and moderate seas are forecast
elsewhere through the forecast period.

...REMAINDER OF THE AREA...

A cold front is approaching the far NW waters, producing
scattered showers north of 27N and between 128W and 133W. Long-
period NW swell is supporting seas to 10 ft north of 25N and west
of 133W. Meanwhile, an upper level trough over the western
waters and tropical moisture result in a large area of scattered
showers and isolated thunderstorms south of 20N and between 105W
and 125W. The rest of the tropical eastern Pacific waters are
under the influence of a 1022 mb high pressure system centered
near 27N143W. The gradient between the aforementioned ridge and
lower pressure associated with the monsoon trough and ITCZ
continues to sustain moderate to locally fresh NE to E winds N of
these boundaries to about 20N and W of 105W. Seas in these
waters are 5-8 ft. Elsewhere, moderate or weaker winds and
moderate seas prevail.

For the forecast, a long-period NW swell progressing across the
NW waters will push southeastward before diminishing Sun night.
Moderate to locally fresh trade winds and locally rough seas
will persist in the western tropical waters through today.
Another large set of NW swell is forecast to arrive to the NW
waters by the end of the weekend and into early next week with
seas peaking around 12 ft.
