Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Sun Nov 30 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
0950 UTC.

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

The monsoon trough extends from 07N78W to 10N110W to 08N128W.
The ITCZ stretches from 08N128W to beyond 06N140W. Numerous
moderate to strong convection extends from 13N to 19N between
108W and 119W. Scattered moderate convection is observed
elsewhere from 19N to 28N between 106W and 123W.

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

Strong high pressure over the eastern United States has shifted
eastward, and winds over the SW Gulf of America are now from the
E to SE. This new wind pattern over the SW Gulf of America acted
to diminish N winds in Tehuantepec to moderate to fresh speeds
while seas remain moderate to 6 ft. The remainder of the basin
is under a weak pressure gradient, allowing for primarily
moderate northerly winds and moderate seas from 18N to 23N,
affecting the offshore waters SW of Cabo San Lucas and the
entrance of the Gulf of California, or from San Jose del Cabo to
Cabo Corrientes. Elsewhere, light to gentle winds and slight to
moderate seas prevail.

For the forecast, fresh winds in the Gulf of Tehuantepec will
reach strong speed tonight into Mon, and then again Tue night
into Wed. Otherwise, a surface trough SW of the Baja California
Sur offshore waters will meander in that region bringing showers,
and also impacting the waters near the Revillagigedo Islands
with fresh to strong NE to E winds through early Mon. Looking
ahead, long-period NW swell will reach the Baja California Norte
offshore waters Tue into Thu before subsiding.

...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 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 Mon morning, and resume again Wed
night through Thu night. Moderate or lighter winds and moderate
seas are forecast elsewhere through the forecast period.

...REMAINDER OF THE AREA...

A cold front is across the far NW waters, extending from 30N130W
to 27N140W and generating scattered showers and tstms N of 26N
between 125W and 133W. Long-period NW swell associated with the
front is supporting rough seas in the 8 to 10 ft range N of 26N
and west of 130W. Meanwhile, an upper level trough over the
western waters and tropical moisture are supporting numerous
moderate to strong convection and isolated thunderstorms from
12N to 20N between 108W and 119W. The rest of the tropical
eastern Pacific waters are under the influence of a 1021 mb high
pressure system centered near 28N146W. 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
130W. Seas in these waters are 5-8 ft. Elsewhere, moderate or
weaker winds and moderate seas prevail.

For the forecast, long-period NW swell progressing across the NW
waters will push southeastward before diminishing tonight.
Moderate to locally fresh trade winds and locally rough seas will
persist in the western tropical waters through this morning.
New large NW swell is forecast to arrive to the NW waters late
today into Mon evening with seas peaking around 12 ft.
