Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Wed Apr 22 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
2000 UTC.

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

A trough axis extends from near 10N75W to 03N81W to 07.5N93W to 
06.5N109W. The ITCZ stretches from 07N110W to 08N121W to beyond 
03N140W. Scattered moderate convection is observed from 02N to 
07N E of 80.5W and from 05N to 08N between 133W and 140W. Scattered
moderate isolated strong convection is noted from 03.4S to 03.5N
between 86W and 105W, and from 00N to 10N between 89W and 129W.

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

A weak cold front has dissipated across the Tiburon Basin of the
Gulf of California and central Baja California southeast of 
Punta Eugenia this afternoon. A broad and weak surface ridge 
prevails across the remainder Baja offshores to the southeast of 
the front to Cabo Corrientes. Recent satellite scatterometer data
showed moderate to fresh NW winds across the Baja waters behind 
the front, and in the far northern Gulf of California. Seas 
across these offshore waters are 7 to 9 ft in NW swell. Ahead of 
the front, moderate NW to N winds prevail, with seas in the 5 to 
7 ft range in mixed S and new NW swell. Across the Gulf of 
Tehuantepec, N gap winds have begun to turn off near the coast, 
but with moderate N winds still extending offshore, where seas 
remain 5 to 6 ft. Elsewhere, winds are light to gentle and seas 
5-6 ft in S swell. Scattered moderate convection is occurring 
well offshore of western Oaxaca and Guerrero. 

For the forecast, new high pressure well NW of the area will 
build across the Baja waters through Thu, and act to increase 
winds modestly through early Fri before weakening Fri night
through Sat. NW swell will continue to move across the Baja 
California waters and spread southeastward to the Revillagigedo 
Islands through Thu. Seas are expected to peak at 8-9 ft across 
the Baja waters this evening through Thu morning with this 
swell. Elsewhere, mostly light to gentle west to northwest winds 
are expected through the weekend.

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

Modest high pressure north of the western Caribbean Sea is
forcing moderate to fresh NE to E gap winds and moderate seas to
7 ft across the Papagayo region, extending downstream to 90W. A 
narrow middle to upper-level trough extending from the
western Caribbean W-SW across central America is supporting 
scattered moderate to strong convection across the waters N of 
10N to the coasts of far western El Salvador and Guatemala, and
shifting westward with the low level winds from Papagayo. Elsewhere,
light to gentle variable winds prevail. Moderate seas in SW 
swell are slowly subsiding across the area waters this morning. 

For the forecast, gap winds will remain moderate across the 
Papagayo region through Thu morning, then become light variable 
through the weekend as southerly winds develop across the NW
Caribbean. Otherwise, rather tranquil conditions are expected to
continue over the Central American and the equatorial waters 
through the end of the week. The next significant SW swell is 
forecast to approach the Galapagos waters Sat night. 

...REMAINDER OF THE AREA...

A weak cold front has dissipated this afternoon across central
Baja California to near 22N130W. Moderate N winds were shown
directly behind the front and E of 120W recently in satellite
scatterometer data. Large NW swell follows the front, supporting
seas of 8-10 ft per recent altimeter data. High pressure well NW
of the front extends weakly into the area and is producing light
to gentle anticyclonic winds behind the front N of 20N. S of 20N,
the developing ridge is supporting moderate to locally fresh 
easterly trade winds to the ITCZ between 120W and 140W. Moderate
seas 5 to 7 ft in S swell, prevail across these waters. 
Elsewhere, moderate or lighter winds and moderate seas are 
prevalent.

For the forecast, modest high pressure N of the area will build
weakly across the region over the next few days to maintain
moderate to fresh trade winds S of 20N to the ITCZ and W of 120W.  
NW swell will spread southeastward over the next few days, 
reaching the trade wind zone by this evening, and leading to 
rough seas around 8 ft there tonight through Thu night. Little 
overall changes are expected with winds and seas elsewhere 
through Sun.
