Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 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 1800 UTC surface analysis and satellite imagery through
1930 UTC.

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

A surface trough extends from 08N77W to 06N94W. The ITCZ extends
from 06N94W to 05N116W to 06N140W. A second ITCZ extends from 
03S90W to 02S104W to beyond 03S120W. Scattered moderate to
isolated strong convection is noted from 03N to 08N between 81N 
and 98W. Scattered moderate convection is noted from 03N to 08N 
between 136W and 140W.

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

High pressure is starting to build SE toward northern waters,
causing some moderate to locally fresh NW winds offshore Cabo San
Lucas and Cabo Corrientes. Otherwise mainly gentle winds 
prevail. Moderate seas prevail, except for slight seas in the 
Gulf of California. 

For the forecast, moderate to fresh winds will continue pulsing 
near Cabo Corrientes and Cabo San Lucas through tonight. Fresh to
locally strong NW winds will dominate offshore Baja California 
Thu into Fri as high pressure builds W of the peninsula. Similar 
winds are likely to redevelop there Sun night and Mon. NW swell 
will bring locally rough seas off Baja California Norte Thu night
through Sat. Looking ahead, strong N gap winds are forecast to 
develop in the Gulf of Tehuantepec Sun night.

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

Moderate to locally fresh NE-E gap winds prevail over the 
Papagayo region. Winds are light to gentle elsewhere. Slight seas
are offshore Colombia, with moderate seas elsewhere.

For the forecast, fresh winds will pulse nightly in the Papagayo
region through the period. Large S-SW swell spreading into the 
waters from offshore Ecuador to the Galapagos Islands will reach 
all area waters by Thu. This swell will build seas to rough from
offshore Ecuador to the Galapagos Islands into Thu night.

...REMAINDER OF THE AREA...

A surface trough that extends from 29N132W to 25N140W disrupts a
general high pressure-dominant regime over area waters. The
result is widespread light to gentle winds, with a build for
moderate NE to E trades from 08N to 16N. Moderate seas prevail
through the basin, although long period southerly swell
approaching the equator today is leading to seas approaching 8 ft
south of the equator.

For the forecast, gentle to moderate winds will dominate the open
waters through tonight as weak high pressure across much of the 
area slowly builds into the Baja California waters. A series of 
troughs will move into the NW waters and weaken W of 130W 
through rest of the week, leading to occasional fresh winds and
possibly some locally rough seas. Large southerly swell will 
reach 10N Thu, then gradually subside. The pressure gradient will
likely 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 will 
likely build seas to rough just S of 30N by late Thu night into 
the weekend.
