Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 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 0000 UTC surface analysis and satellite imagery through
0330 UTC.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A surface trough extends west-southwestward from 08N78W to
05N92W. An ITCZ extends from 05N92W to 03N110W to 03N135W.
Scattered moderate to isolated strong convection is noted from
04N to 09N between 82W and 91W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
The pressure gradient between high pressure west of the area and
a trough over the Gulf of California is supporting moderate to
fresh NW to winds west of Baja California, with moderate winds
extending southward to near the Revillagigedo Islands and off
Cabo Corrientes. Gentle to moderate S to WSW winds exist in the
Gulf of California. Light to gentle winds are seen across the
offshore waters of southern Mexico. Moderate seas 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 Fri through
Sat evening. Fresh NW to N winds will pulse in the northern Gulf
of California Fri 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 prevailing for
the rest of the offshore waters.
For the forecast, fresh with 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 1027 mb high west of
California across 30N129W to near the Revillagigedo Islands. A
trough of Low pressure cuts across the northwestern corner of the
discussion area from 30N134W to 25N140W. Fresh to locally strong
winds are found near the trough of low pressure. 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 94W.
For the forecast, the pressure gradient between the aforementioned
ridge and low pressure will support fresh to locally strong NE-E
winds N of 25.5N and W of 133W and locally rough seas tonight.
These conditions will then drift north through Fri before
shifting north of the area. Large southerly swell will gradually
subside. The pressure gradient will likely tighten north of the
ITCZ to 20N and west of 110W by the end of the week through the
weekend, 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 south of 30N in the north-central
waters by early Fri into the weekend.
