Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Fri Oct 30 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 1200 UTC surface analysis and satellite imagery through
1530 UTC.

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

The monsoon trough extends from 10N86W to 06N91.5W. The ITCZ is 
analyzed from 06N91.5W to 07N117W. A trough extends from 06N128W
to a 1010 mb low pres near 08N136W. Scattered to numerous
moderate convection is depicted from 02N to 09N between 131W and
140W. Scattered moderate convection is depicted from 02N to 08N 
between 89W and 117.5W. Similar convection is also depicted from
00N to 10N between 121W and 130W. 

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

Fresh to strong N to NE gap winds are occurring over the Gulf of
Tehuantepec with seas 6-8 ft. The pressure gradient between
higher pressures over Mexico and a trough along the Gulf of 
California is supporting moderate to fresh S to SW winds over the
southern and northern parts of the Gulf. Elsewhere, winds are 
moderate or weaker with 5-7 ft over the Pacific waters, 2-4 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 and diminish by
Mon night. A developing extratropical cyclone should move into 
the waters west of the Baja California peninsula and over the N 
Gulf of California Sat night into Sun with fresh to strong SE to 
SW winds. Fresh SW winds should occur over the Gulf of California
on Sun in the wake of the extratropical cyclone. 

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

Fresh NE to E gap winds are occurring over the Gulf of Papagayo 
region. Moderate to fresh N winds along seas to 6 ft are present
over the Gulf of Panama. Elsewhere, winds are moderate or 
weaker. Seas are 4-6 ft. Scattered moderate convection is also 
occurring from 00N-07N east of 83W.

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

...REMAINDER OF THE AREA...

A 1008 mb low is centered near 26.5N135W with a developing cold
front extending southwestward to 15N146W and a developing warm
front extending northeastward to 26N126W. Northeast to east winds
prevail north of the low with seas to 8 ft. Elsewhere, the 
pressure gradient between weak ridging north of our waters and 
lower pressure over the monsoon trough is forcing only moderate 
or weaker trades across the forecast waters. Large, long-period 
SW swell is reaching northward across the equator to 07N between
97W-130W. Elsewhere seas are 4-7 ft.

For the forecast, the low will become an extratropical cyclone  
this morning and then move slowly eastward. By tonight, fresh to
strong S to SW winds will develop south of the warm front and 
fresh to strong N to NE winds should occur north of the cold 
front. The system should move over the offshore zones west of the
Baja California peninsula on Sun with winds and seas diminishing
by Sun night.
