Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Sun Apr 12 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
0730 UTC.

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

A surface trough extends from 10N74W to 01.5N84W to 04N95W. The 
ITCZ extends from 04N95.5W to 01.5N111W to 04N128W to 09N135W to
beyond 08N140W. A southern hemispheric ITCZ extends from 03.4S99W
to 03S101W to beyond 03.4S107W. Scattered moderate convection is
noted from 01N to 06N between 84W and 90W. Scattered moderate 
isolated strong convection is noted from 02.5N to 07.5N between 
91W and 121W, and from 05N to 10N between 132W and 140W. 
Scattered moderate convection is S of 03S between 101W and 104W.

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

A very weak surface ridge extends eastward into the waters of 
Baja California, to the south of a cold front approaching the 
region from the northwest. This pattern is supporting light to 
gentle NW to N winds across the waters of Baja, then becoming 
gentle N to NE winds from Baja Sur beyond the Revillagigedo 
Islands. Moderate seas to 5 ft in mixed NW and SW swell prevail 
across these waters. Light to gentle winds are in the Gulf of 
California with slight seas, except in northern portions where 
fresh to strong SW gap winds have developed tonight. Seas have
built quickly there to 4 to 6 ft. Farther east, gentle NW winds 
prevail across the waters from Las Tres Marias to Puerto Angel,
except moderate winds near the coast of Cabo Corrientes. Strong 
N gap winds have expanded offshore of the Tehuantepec region 
to 14N, where seas are now 6 to 9 ft. An upper level trough 
shifting slowly eastward across the area now extends from Baja 
Sur northward into NW Mexico, with associated clouds and showers 
now across interior Mexico. 

For the forecast, a cold front will move into the Baja Norte
waters early Mon then gradually dissipate across central Baja and
the Gulf of California Tue. Expect light to gentle NW to N winds
across the Baja waters ahead of the front, before winds begin to
freshen Mon evening through Tue. High pressure behind the front
will dominate the region through the rest of the week. Fresh to 
strong SW to W gap winds are expected in the northern Gulf of 
California tonight through Mon night, ahead of the front, with 
winds then becoming moderate to fresh from the N through the 
entire Gulf Tue morning through Wed. Elsewhere between Baja Sur 
and Puerto Angel, winds will be moderate or weaker with moderate 
seas through Tue. Pulsing fresh to strong northerly gap winds 
will prevail across and downwind of the Tehuantepec region 
through Tue morning, with seas building to 8 ft during the early 
mornings. Afterwards, mainly moderate and variable winds are 
expected through midweek.

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

Fresh to strong NE to E gap winds prevail across the Papagayo
region and extend downwind to near 90W, producing rough seas of 
7 to 9 ft. Moderate to fresh N to NE winds and moderate seas of 
4 to 6 ft in SW swell prevail in the Gulf of Panama, and extend 
beyond the Azuero Peninsula to 04N. Light to gentle winds and 
moderate seas 4 to 5 ft in SW swell dominate the remainder of the
offshore forecast waters. Scattered moderate convection continues
offshore of western Panama and Costa Rica.

For the forecast, broad high pressure will continue N of the
area through Wed before weakening, and maintain fresh gap winds 
pulsing to strong during the nighttime and early morning hours 
across the Papagayo region and downwind to 90W. Winds up to 30 
kt, and seas up to 9 ft are forecast early this morning and 
again Sun night. In the Gulf of Panama, moderate northerly winds,
pulsing to fresh each night, are expected throughout the 
forecast period. Light to gentle winds and moderate seas will 
prevail elsewhere. Cross-equatorial SW swell will raise seas to 
6 to 8 ft between Ecuador and the Galapagos Islands Tue through 
Wed. Pulses of active convection will continue across the waters 
S of 09N through Mon, and will propagate westward.

...REMAINDER OF THE AREA...

High pressure NW of the area extends a ridge southward through 
30N142W and into the area W of 130W. Est of the ridge, a
weakening cold front has crossed into the local waters, passing
through 30N126W to 28N131W. A very weak ridge prevails ahead of
this front and extends to near the Revillagigedo Islands. An 
upper level trough continues to move slowly eastward across the 
area N of 18N and east of 118W, with associated clouds and 
weather recently shifting well inland across interior Mexico. 
The pressure gradient between the ridge and lower pressures in 
the vicinity of the ITCZ supports moderate to fresh winds N of 
the ITCZ to about 15N between 98W and 124W, and south of 22N to 
the west of 124W. Moderate seas in mixed NW and S swell 
generally prevail across the area waters, with seas 7 to 8 ft 
within the trade wind zone between 90W and 115W.

For the forecast, a broad and weak high pressure ridge will
dominate the weather pattern across the northern forecast waters
through early Mon, with little change in winds and seas, before 
the high shifts southeast Mon through midweek to strengthen the 
pressure gradient modestly. Moderate winds are expected in the 
trade wind zone W of 95W through Mon. A weakening cold front 
across the northern waters W of 125W will move into the Baja 
Norte early Mon then across northern Gulf California late Mon. 
Moderate N to NE winds and moderate seas 7 to 8 ft in NW swell 
are forecast in the wake of the front.
