Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Sat Oct 31 2026

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
2200 UTC.

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

The monsoon trough extends from 10N85W to 01N133W. Scattered
moderate convection is depicted S of 11N and E of 135W. Scattered
moderate to strong convection is S of 07N between 100W and 115W.

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

Fresh to strong N to NE gap winds are occurring over the Gulf of
Tehuantepec with seas of 5-8 ft. The pressure gradient between
higher pressures over Mexico and a trough along the Gulf of
California is supporting moderate to locally fresh S to SE winds
over southern portions of the Gulf. Elsewhere, winds are
moderate or weaker with 4-6 ft over the Pacific waters, 2-5 ft
over the N and central Gulf of California.

For the forecast, fresh to strong N gap winds over the Gulf of
Tehuantepec will continue through early next week, diminishing
Mon night. A developing extratropical cyclone should move into
the waters west of the Baja California peninsula and over the N
Gulf of California tonight into Sun with strong to near-gale SE
to SW winds and seas to 8 ft. Fresh to strong SW winds along
with seas of 5-6 ft should occur over the Gulf of California on
Sun in the wake of the extratropical cyclone. Moderate or weaker
winds will likely return to the offshore waters Sun into Mon.

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

Fresh to strong NE to E gap winds are occurring over the Gulf of
Papagayo region with seas 5 to 7 ft. Moderate N winds along with
seas of 4 to 6 ft are present over the Gulf of Panama.
Elsewhere, winds are moderate or weaker. Scattered moderate
convection is occurring S of 08N east of 93W.

For the forecast, fresh to strong NE to E gap winds over the
Gulf of Papagayo region will continue through Mon. Fresh N winds
over the Gulf of Panama should continue today before weakening
on Sat. Large, long-period SW swell has reached the equatorial
waters, and will gradually diminish on Sun.

...REMAINDER OF THE AREA...

A 1006 mb low is centered near 26N125W, with a cold front
extending southwestward to 15N135W, and a warm front extending
from the low to 18N134W. Fresh to strong winds in counter-
clockwise flow surrounds the low from 20N to 30N between 119W and
129W, with seas to 8 ft. Moderate to fresh southwest winds are
found farther southwest along the cold front. Elsewhere, the
pressure gradient between weak ridging north of the region and
lower pressure near the monsoon trough is supporting only
moderate or weaker trades across the forecast waters. Large,
long-period SW swell is expanding northward across the equator to
09N between 87W-134W. Elsewhere, seas are 4-7 ft.

For the forecast, the low will become a strong extratropical
cyclone and then move slowly eastward through the weekend. The
system should move over the offshore zones west of the Baja
California peninsula on Sun with winds and seas diminishing by
Sun night.
