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

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

A surface trough extends from 08N77W to 06.5N90W. The ITCZ 
extends from 06.5N90W to 04N105W to 06N124W to beyond 06N140W.
A second ITCZ extends from 02.5S88W to 02S102W to beyond
03.4S120W. Widely scattered moderate isolated strong convection
is noted from 03N to 08.5N between 81W and 98W. Scattered 
moderate convection is noted from 04N to 07N between 124W and 
129W, and from 03N to 08N between 136W and 140W.

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

Fresh to strong S to SW winds are in the northernmost Gulf of 
California, flowing into low pressure over southern California
per a recent ASCAT scatterometer pass. Moderate to fresh NW winds
are near Cabo San Lucas per the same ASCAT data. Elsewhere, 
mainly gentle winds dominate. 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 sunrise. Moderate to fresh 
winds will continue pulsing near Cabo Corrientes and Cabo San 
Lucas into tonight. 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
in the Gulf of Panama. 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 through this
morning, with winds pulsing to moderate to fresh thereafter. 
Large S-SW swell will spread into the waters from offshore 
Ecuador to the Galapagos Islands later today, 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 continue to dissipate over the NW waters. 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 20N. Similar winds are found S of
05N and E of 105W under a weak pressure pattern. Gentle to 
moderate winds are elsewhere. Seas are moderate across the open 
waters.

For the forecast, gentle to moderate winds will dominate the open
waters into tonight as weak high pressure across much of the 
area slowly builds into the Baja California waters. A series of 
weak frontal boundaries or troughs will move into the NW waters 
and weaken W of 130W throughout the remainder of the week. 
Moderate seas generally will continue into late week. Large 
southerly swell will move into the waters S of the Equator later
today, 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.
