Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Fri Apr 3 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
1500 UTC.

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

A surface trough extends southwestward from 09N84W to 06N96W. The
ITCZ continues from 06N96W to 05N110W to 04N133W. A second ITCZ 
is mainly south of the Equator and runs from 00N85W to 04S105W 
to beyond 03S120W. Convection is limited at this time.

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

A ridge dominates the offshore forecast waters of Baja California
supporting fresh to locally strong NW winds N of Punta Eugenia,
wind moderate to fresh NW winds extending southward to Cabo San
Lucas. Light to gentle winds are noted across the Gulf of 
California, and also across the remainder of the Mexican offshore
waters, including the Gulf of Tehuantepec. Moderate seas, in S 
swell, prevail across the open waters off Mexico, with slight 
seas over the Gulf of California.

For the forecast, fresh to locally strong NW winds offshore Baja
California will become gentle to moderate this weekend, then 
increase to between moderate and fresh by Mon. NW swell will also
bring locally rough seas off Baja California Norte through Sat 
morning. Fresh NW to N winds will pulse in the northern Gulf of 
California this afternoon through Sat morning. In the long term,
strong to near gale-force N gap winds along with rough seas are 
expected in the Gulf of Tehuantepec Sun night through midweek 
next week. 

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

Moderate to fresh NE to E gap winds prevail over and downstream the
Papagayo region. Winds are light to gentle elsewhere. Slight seas
are offshore Colombia, with moderate seas in S swell prevailing 
for the rest of the offshore waters.

For the forecast, fresh to locally strong gap winds are expected
during the nighttime and early morning hours in the Papagayo 
region through midweek next week. Residual southerly swell will 
maintain moderate seas off Ecuador and near the Galapagos Islands
through this weekend. Afterward, seas should gradually subside 
next week.

...REMAINDER OF THE AREA...

A surface ridge extends southeastward from a 1028 mb high pressure
located west of California near 39N133W across the northern forecast
waters to near the Revillagigedo Islands. Farther south, a surface
trough is analyzed and extends from 13N136W to 03N135W. Scattered
showers and isolated thunderstorms is noted where the trough
meets the ITCZ. The pressure gradient between the surface ridge 
and lower pressure in the vicinity of the ITCZ is supporting 
gentle to moderate winds elsewhere north of the ITCZ. Light to 
gentle winds prevail south of the ITCZ. Moderate to rough seas in
cross equatorial swell prevail south of 10N and west of 120W,
except in the lee of the Galapagos Islands. Several altimeter
passes confirmed the presence of these sea heights.

For the forecast, the pressure gradient around the southern periphery
of the ridge and a trough over the NW corner of the forecast region
will support moderate to fresh easterly winds and moderate to locally
rough seas N of 27N W of 130W today, then become gentle to moderate
by late tonight. Moderate NE to E winds with moderate seas in persistent
S swell should continue from the ITCZ to 20N through Tue. A new set
of NW swell, associated with a cold front, is going to bring back
rough seas near 30N140W by Tue.
