Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Wed Apr 1 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
0000 UTC.

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

A surface trough extends from 08N78W to 06N90W. The ITCZ 
extends from 06N90W to 04N104W to 06N124W to beyond 05N140W. A 
second ITCZ extends from 03S89W to 02N102W to beyond 03.4S120W.
Widely scattered moderate isolated strong convection is noted 
from 03N to 08N between 82W and 98W. Scattered moderate 
convection is noted from 03N to 06N between 102W and 104W, from 
02S to 03.4S between 113W and 117.5W, and from 02.5N to 08N 
between 136W and 140W.

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

Fresh to strong S to SW winds are developing in the northernmost
Gulf of California, flowing into low pressure over southern 
California. Elsewhere, mainly gentle winds dominate, although 
some moderate NW winds are ongoing near Cabo Corrientes and Cabo 
San Lucas. Moderate seas prevail, except for slight seas in the 
Gulf of California away from the fresh to strong winds. 

For the forecast, fresh to strong S to SW winds in the northern 
Gulf of California will diminish by Wed morning. Moderate to 
fresh winds will continue pulsing near Cabo Corrientes and Cabo 
San Lucas into Wed night. Fresh to locally strong NW winds will 
dominate offshore Baja California Thu and Fri as high pressure 
builds W of the peninsula, and then again fresh Sun night. NW 
swell will bring locally rough seas off Baja California Norte Fri
through Sat night. Looking ahead, fresh to strong N gap winds 
may develop in the Gulf of Tehuantepec by Sun night.

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

Fresh to locally strong NE-E winds prevail over the Papagayo 
region, with seas to around 7 ft. Moderate N-NE winds are
developing from the Gulf of Panama southward to around 06N. 
Winds are light to gentle elsewhere. Slight seas are offshore 
Colombia, with moderate seas elsewhere.

For the forecast, fresh NE-E winds will pulse to strong across 
and downwind of the Papagayo region to near 90W tonight into
early Wed, with winds pulsing to moderate to fresh thereafter. 
Large S-SW swell will spread into the waters from offshore 
Ecuador to the Galapagos Islands by Wed morning, and reach the 
remaining area waters and Central American coasts Thu. This swell
will build seas to rough from offshore Ecuador to the Galapagos 
Islands through Thu night.

...REMAINDER OF THE AREA...

Frontal remnants are from near 30N129W to 20N140W. Weak high 
pressure is centered near the Revillagigedo Islands. An overall 
modest pressure gradient between these two features and the ITCZ 
to the south is leading to widespread light to gentle winds
across the waters N of 22N and W of 120W, with gentle to moderate
winds elsewhere. Seas are moderate across the open waters.

For the forecast, gentle to moderate winds will dominate the open
waters into Wed night as weak high pressure across much of the 
area slowly builds into the Baja California waters. A series of 
weak frontal boundaries will move into the NW waters and weaken W
of 130W throughout the week. Moderate seas generally will 
continue into late week, large southerly swell will move into 
the waters S of the Equator into Wed, reach 10N Thu, then 
gradually subside. The pressure gradient may tighten N of 05N and
W of 110W by the end of the week increasing trades to moderate 
to locally fresh, with seas building locally to rough as a 
result. Northerly swell may build seas to rough just S of 30N by 
late Thu night into the weekend. Meanwhile, a trough extending
from low pressure just W of 140W may lift across the NW waters
during the end of the week, with fresh winds N of it to 30N and
building seas to rough. NW swell may push SE of 30N into the
N-central waters by the end of the week into the weekend with
locally rough seas.
