Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Mon Apr 13 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
0800 UTC.

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

A surface trough extends from 09.5N74.5W to 03N84W to 04.5N98W. 
The ITCZ extends from 05.5N100W to 06.5N117W to 04N130W to 
beyond 05N140W. A southern hemispheric ITCZ extends from 
03.4S92W to 02S106W to beyond 03.4S120W. Scattered moderate 
convection is noted E of 79W, from 01N to 08N between 83W and 
93W, and from 03.5N and 06.5N between 120W and 136W. Scattered 
to locally numerous moderate to strong convection is noted from 
04N to 08N between 92W and 120W. Scattered moderate convection is
noted S of 02.5S between 86W and 96W near the southern 
hemispheric ITCZ.

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

A weak cold front has moved into Baja California Norte 
overnight, and extends southwestward across the offshore waters 
through 28N120W. Weak high pressure is collapsing ahead of the 
front and yielding light to gentle NW to N winds across the 
nearshore waters of Baja, and light NE winds farther offshore 
becoming gentle NE winds across the Revillagigedo Islands. 
Moderate seas to 5 ft in mixed swell prevail across these waters.
Narrow bands of showers and isolated thunderstorms are occurring
along and just ahead of the front across the open waters, and 
along the ridgeline of the mountains across north and central 
portions of the Baja Peninsula. Behind the front, light to gentle
NW winds prevail, with seas 5 to 7 ft in fresh NW swell. Gentle 
N winds prevail across southern portions of the Gulf of 
California seas of 3 to 4 ft, while fresh to strong SW gap winds 
and moderate seas prevail continue across north portions of the 
Gulf. Farther east, gentle NW to W winds prevail across the 
waters from Las Tres Marias to Puerto Angel, except moderate 
winds near the coast from Cabo Corrientes to Acapulco. Fresh N 
gap winds are noted in the Tehuantepec region N of 15N, where 
seas are around 6 ft. 

For the forecast, the cold front will move slowly across the 
Baja Norte waters and the extreme north portions of the Gulf of
California today, then gradually dissipate across central Baja 
and the central Gulf of California on Tue. Expect light to 
gentle NW to N winds across the Baja waters tonight and Mon ahead
of the front, before winds begin to freshen Mon evening through 
Tue. High pressure behind the front will build across the region 
and dominate conditions through the rest of the week. Fresh to 
strong SW to W gap winds are expected in the northern Gulf of 
California through around midnight Mon night ahead of the front,
with winds then becoming moderate to fresh from the N through 
the entire Gulf early Tue morning through Wed evening. 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 late Tue morning. Afterwards, 
moderate and variable winds are expected there through Fri.

....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 tonight, producing rough 
seas to 8 ft. Moderate to fresh N winds and moderate seas in SW 
swell prevail in the Gulf of Panama, and extend beyond the Azuero
Peninsula to near 05N. Light to gentle winds and moderate seas 
in SW swell dominate the remainder of the offshore forecast 
waters. Widely scattered moderate convection continues across 
the near and offshore waters of western Panama and Costa Rica,
while strong convection occurring over NW Colombia is reaching
the Pacific coast and waters within 20 nm.

For the forecast, broad high pressure will continue N of the
area through Wed before weakening, and will maintain fresh gap 
winds pulsing to strong during the nighttime and early morning 
hours across the Papagayo region to near 90W. 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 evening. 

...REMAINDER OF THE AREA...

High pressure NW of the area extends a ridge southward through 
30N14W and into the area W of 124W. East of the ridge, a cold 
front has entered the local waters tonight, passing through 
30N116W to near 25N136W. Weak high pressure ahead of this front 
is collapsing. Gentle to moderate N to NE winds prevail north of
the front, with building seas 6 to 8 ft in NW swell. The 
pressure gradient between the ridge and lower pressures in the 
vicinity of the ITCZ supports moderate trade winds N of the ITCZ
to about 15N between 97W and 124W, and moderate to fresh winds south
of 25N to the west of 124W. Moderate seas in mixed NW and S 
swell generally prevail across the area waters south of the 
front, with seas to 7 ft within the trade wind zone between 95W 
and 120W.

For the forecast, the weak high pressure ridge will dominate the
weather pattern across the northern forecast waters through 
Mon with little change in winds and seas, before high pressure 
behind the front shifts southeastward to near 33N through 
midweek, and strengthens the pressure gradient across the local 
area modestly. A weakening cold front across the northern waters 
will move into the central Baja Peninsula to near 22N134W by Tue 
then gradually dissipate. Moderate N to NE winds and moderate 
to briefly rough seas in NW swell are forecast in the wake of 
the front through Wed. Moderate winds are expected in the trade 
wind zone W of 95W through Mon, becoming moderate to locally 
fresh Tue through Fri.
