Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 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 1200 UTC surface analysis and satellite imagery through
1520 UTC.

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

A trough axis extends from near 10N74W to 02N81W to 06N100W to 
04N114W. The ITCZ stretches from 04N114W to beyond 01N140W. 
Scattered moderate convection is observed from 01.5N to 06.5N E
of 80.5W, from 03.4S to 04N between 86W and 94W, S of 00N between
95W and 108W, and from 00N to 08.5N between 98W and 140W.

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

A weak cold front continues to move across Baja California Norte
and adjacent waters this morning, while a broad and weak surface
ridge prevails across the remainder Baja offshores to the 
southeast of the front. Overnight satellite scatterometer data 
confirmed moderate to fresh NW winds ahead of the front from 
Sebastian Vizcaino Bay to Punta Abreojos where altimeter data 
show seas in the 4 to 7 ft range in mixed S and new NW swell. 
Recent satellite altimeter data shows seas of 8 to 9 ft in this 
area of fresh NW winds just offshore of Sebastian Vizcaino Bay. 
In the northern Gulf of California, moderate to fresh NW to N 
winds are beginning to fill in across the Gulf behind of the 
front. In the Gulf of Tehuantepec, N gap winds are moderate to 
fresh and seas to 5-6 ft. Elsewhere, winds are light to gentle 
and seas 5-6 ft in S swell, except to 3 ft in the Gulf of 
California. Scattered moderate convection is occurring over 
portions of western Oaxaca and eastern Guerrero and the adjacent 
waters. 

For the forecast, high pressure in the Gulf of America will 
continue to weaken today as it shifts northeastward, leading to 
a significant decrease in gap winds across the Gulf of 
Tehuantepec. The weak cold front will continue to move 
southeastward and dissipate across central Baja later today. New
high pressure behind this front will build across the Baja 
waters today through Thu, and act to increase winds modestly 
through early Fri before weakening into Fri night. NW swell 
generated behind the front will continue to move across the Baja 
California Norte waters and spread southeastward to the 
Revillagigedo Islands through Thu. Seas are expected to peak to 
at 8-9 ft across north and central portions of the Baja waters 
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 fresh NE to E gap winds and moderate seas to 6 ft across
the Papagayo region, extending downstream to 88W. Elsewhere, 
light to gentle variable winds prevail. Moderate seas in SW 
swell is slowly subsiding across the area waters this morning. A
narrow middle to upper-level trough extending from the western
Caribbean W-SW across central America is supporting scattered
moderate isolated strong convection across the waters N of 10N to
the coasts of El Salvador and Guatemala, with scattered weakening
convection across the nearshore waters of Costa Rica.

For the forecast, gap winds will pulse moderate to fresh speeds 
across the Papagayo region through this morning, then become 
light variable through the weekend. 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 SW 
waters Sat night. 

...REMAINDER OF THE AREA...

A weakening cold front continues to slide southeastward across 
the NE waters, extending from the northern Gulf of California
across Baja Norte to near 25N121W, then becomes stationary, 
stretching to 21N139W. No significant convection is seen near 
this boundary. Large NW swell follows the front, supporting seas 
of 8-11 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. Weak high 
pressure SE of the front dominates the remainder of the basin, 
supporting moderate to locally fresh easterly trade winds from 
07N to 20N between 120W and 140W as shown by overnight 
scatterometer data. Moderate seas 5 to 7 ft in S swell, prevail 
between the front and the ITCZ. Elsewhere, moderate or lighter 
winds and moderate seas are prevalent.

For the forecast, the aforementioned frontal boundary will move 
east-southeastward, and dissipate as it moves into the central 
Baja waters later today. The NW swell behind the front 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.
