NWS National Hurricane Center Miami FL
0405 UTC Fri Jan 9 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 0000 UTC surface analysis and satellite imagery through
0350 UTC.

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

The monsoon trough extends from 10N85W to 06N97W. The ITCZ 
continues from 06N97W to 07N110W to 08N123W then resumes near
05N129W to 05N140W. Scattered moderate convection is from 07N to
13N between 86W and 95W.

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

High pressure building into the SW United States is leading to
fresh to strong NW winds offshore Baja California Norte N of
Punta Eugenia, where seas of 8 to 13 ft are present. Elsewhere 
offshore Baja California, moderate to fresh NW winds and seas of
5 to 7 ft are ongoing. In the Gulf of California, moderate to
fresh NW winds are N of 30N and at the entrance of the Gulf while
seas remain slight to 3 ft. Light to gentle winds and slight to
moderate seas in NW swell are elsewhere. 

For the forecast, a large area of gale-force gap winds and very 
rough seas will occur across and well downwind of the Gulf of 
Tehuantepec beginning Sat night as a strong cold front moves 
through southern Mexico. Near storm-force winds are possible Sun
night, with gales persisting through at least Mon night. Large 
swell will reach as far south as the Revillagigedo Islands into 
Sun, with very rough seas north of Cabo San Lazaro through Fri 
night. Strong high pressure building north of the area over the
Great Basin will support strong NW winds and rough seas across 
the Gulf of California tonight into Mon. 

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

High pressure extending across the northwest Caribbean and the
Yucatan is supporting moderate to fresh NE gap winds across the 
Papagayo region. Moderate to fresh northerly gap winds are also 
ongoing across the Gulf of Panama. Elsewhere, light to gentle 
winds and slight to moderate seas primarily in SW swell prevail.

For the forecast, high pressure north of the region will support
fresh to occasionally strong winds across the Papagayo region 
through early next week. Pulsing fresh northerly winds are also 
expected across the Gulf of Panama tonight. Gentle to moderate 
breezes and slight to moderate seas will persist elsewhere. 

...REMAINDER OF THE AREA...

High pressure building well north of the area is supporting 
moderate to fresh NE to E winds north of 09N and west of 117W, 
where seas are 7 to 10 ft. Gentle to moderate E to SE wind with 
5 to 7 ft seas in N swell are noted south of the ITCZ and west 
of 110W. Mainly gentle breezes and moderate seas are evident 
elsewhere.

For the forecast, high pressure north of the region will support
fresh trade winds and rough seas from 09N to 22N west of 117W 
through Fri night. NW swell will keep rough seas in place for 
waters north of 15N into the weekend. Looking ahead, another 
round of large NW swell will pass southeast of 30N140W Sat night,
and cover the area north of 10N and west of 120W by late Mon.
