Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Wed Mar 25 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 0600 UTC surface analysis and satellite imagery through
0830 UTC.

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

A surface trough extends from low pressure in northern Colombia
southwestward to 08N78W and to 05N90W, where it transitions to 
the ITCZ and continues to 05N110W to 05N120W to 04N130W to 
beyond 03.5N140W. Scattered moderate to isolated strong convection 
is within 60 nm of the ITCZ between 117W-121W. Scattered moderate 
convection is within 60 nm north of the ITCZ between 95W-98W, and 
within 30 nm of the ITCZ between 128W-129W.

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

Light to gentle northwest to north winds are over the waters 
west of Baja California, and mostly light and variable winds over
the remainder of the offshore waters W of Tehuantepec. Seas are 
in the range of 4 to 6 ft in northwest swell over the offshore 
waters west of Baja California, and 3 to 4 ft over the remainder 
of the Mexican offshore waters. In the Tehuantepec region, fresh 
to strong northerly winds prevail with seas to near 8 ft. A 
0403Z scatterometer satellite data pass confirmed the presence 
of these winds. In the Gulf of California, winds are generally 
light and variable except in the central part of the Gulf where 
gentle west winds are present. Seas are 3 ft or less in the Gulf.

For the forecast, high pressure west of Baja California will 
continue to support the mostly light to gentle northerly wind 
flow over the waters west of Baja, and mostly light and variable 
winds over the remainder of the offshore waters through the 
forecast period, with the exception of winds pulsing to moderate
speeds north of Cabo San Lazaro tonight through late Thu night, 
then north of Punta Eugenia through the rest of the forecast 
period. Northwest swell will build seas to 9 ft north of Punta 
Eugenia Thu through Fri night before subsiding. Fresh to strong 
north gap winds in the Gulf of Tehuantepec will pulse nightly 
through the rest of the week with rough seas. A frontal boundary 
will move across the Gulf of America this weekend. The pressure 
gradient in the Tehuantepec region will tighten leading to gale- 
force northerly winds there north of 14N beginning Sat night.

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

The gradient associated to relatively weak high pressure over 
the western Atlantic is inducing fresh to strong northeast to 
east winds in the Gulf of Papagayo region as noted in overnight 
scatterometer satellite data. Seas with these winds are 4 to 6 
ft. Farther east, moderate north to northeast winds are in the 
Gulf of Panama reaching southward to near 06N. Seas are 3 to 5 ft
with these winds. Elsewhere, light to gentle winds and moderate 
seas prevail.

For the forecast, the fresh to strong northeast to east winds 
in the Gulf of Papagayo region will pulse nightly going into the
upcoming weekend along with moderate to rough seas. Moderate to
occasionally fresh north to northeast winds will pulse in the 
Gulf of Panama during this time. Gentle breezes and moderate seas
will prevail elsewhere. 

...REMAINDER OF THE AREA...

The pressure gradient between modest high pressure north of 16N 
and west of 121W, and lower pressure near the ITCZ is currently 
sustaining mostly moderate trades from 04N to 19N between 127W 
and 139W, and from 04N to 13N between 113W and 127W as depicted 
in overnight scatterometer satellite data passes. Seas are 5 to 
7 ft over these waters. Elsewhere, overnight scatterometer 
satellite data indicates light to gentle northeast to east winds.
Seas are 4 to 6 ft elsewhere primarily due to a long- period 
northwest to north swell. The tail-end of a cold front just 
touches 30N140W, and stretches well southwestward from there as a
dissipating stationary front.

For the forecast, fresh to strong northeast to east winds will 
develop north of about 26N and west of 119W Thu through Fri as 
the pressure gradient tightens between a ridge building southward
across the north-central waters, and a low pressure system, with 
attendant trough lifting northward west of the area near 145W. 
Seas are expected to build to 8 to 10 ft over this part of the 
area.
