Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Wed Apr 15 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 10N85W to 03.5N98W to 04.5N104W to
03.5N120W. The ITCZ extends from 03.5N123W to 05N134W to beyond 
04.5N140W. Southern hemispheric ITCZ extends from 02S113W to 
to beyond 02.5S120W. Numerous moderate to strong convection is 
noted from 02N to 06.5N between 85W and 101W. Scattered moderate
isolated strong convection is noted S of 02N between 86W and 
98W, and from 02.5N to 10N between 111W and 140W.

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

High pressure continues to build gradually southward across the
Baja California waters tonight, as a weak cold front has
dissipated across central Baja and the central Gulf of 
California this past afternoon. This current pressure pattern is
producing moderate to fresh NW to N winds across the Baja waters
becoming moderate N to NE winds from 21N southward across the 
Revillagigedo islands. Seas across these offshore waters are 6 
to 7 ft in NW swell, except to 8 ft near Punta Eugenia and 
across Bahia de Sebastian Vizcaino, where fresh winds have 
prevailed since this afternoon. Moderate to locally fresh N-NW 
prevail across the Gulf of California, and extend southward to 
offshore of Cabo Corrientes. Seas are 3 to 5 ft across these 
waters. However, wind have become light and variable across 
northern portions of the Gulf since this evening. Gentle to 
moderate NW to W winds prevail across the remaining waters 
between Cabo Corrientes and Puerto Angel, where seas are 4 to 5 
ft in SW swell. Fresh N gap winds are across the waters inside 
the Gulf of Tehuantepec, where seas are 5 to 6 ft. 

For the forecast, moderate to fresh NW winds will prevail across 
the waters on both sides of the Baja California Peninsula tonight
as high pressure builds in from the North Pacific. This ridging 
will then dominate the waters through the week and maintain
generally moderate winds. New NW swell will propagate into Baja 
waters late Thu and produce rough seas across the outer waters of
Baja Norte into early Sat. Between Baja Sur and Puerto Angel, 
winds will be moderate or weaker with moderate seas through Fri. 
Fresh northerly gap winds are expected across the Tehuantepec 
through this morning before winds there become variable 
throughout the remainder of the week. Looking ahead, high 
pressure will weaken across the region Sat leading to diminishing
winds and seas through the weekend.

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

Overnight satellite scatterometer data showed fresh to strong NE
to E gap winds across the Papagayo region, extending northward
across the waters of northern Nicaragua, and downwind to near 
90W. These winds were producing seas 6 to 8 ft. Moderate to 
locally fresh N to NE winds and moderate seas to 6 ft prevail in 
the Gulf of Panama and extend beyond the Azuero Peninsula to near
04.5N. Light to gentle winds and moderate seas in S-SW swell 
dominate the remainder of the offshore forecast waters. Scattered
moderate to strong convection remains active S of 06N, to the N 
and NE of the Galapagos Islands. Isolated showers dot the near 
and offshore waters of Costa Rica and are widely scattered 
between SW Colombia and the Galapagos Islands.

For the forecast, broad high pressure will continue N of the 
area into Wed night before gradually weakening through the end 
of the week. This will maintain fresh gap winds pulsing to strong
during the nighttime and early morning hours across the Papagayo
region to near 90W through Wed night, then yield moderate winds 
pulsing to fresh each night into the weekend. In the Gulf of 
Panama, moderate northerly winds will pulse to fresh tonight and
Wed night, then will diminish slightly through the rest of the 
week. Light to gentle winds and moderate seas will prevail 
elsewhere. Active convection occurring N of the Galapagos tonight
will gradually shift westward and out of the area through Fri
night.

...REMAINDER OF THE AREA...

1026 mb high pressure is centered N of the area near 34N132W and
extends a ridge southward across the region W of 108W. The 
pressure gradient between the ridge and lower pressure in the 
vicinity of the ITCZ supports moderate to fresh trade winds south
of 16N between 100W and 110W, and moderate to fresh NE to E 
winds south of 25N and west of 110W. Seas are generally 5 to 8 
ft in mixed swell across the area, except less than 5 ft across 
the far NW waters near the high pressure center. Scattered to 
locally numerous convection has become more active along and N of
the ITCZ and trough between 88W and 100W, and between 120W and 
130W, and is producing areas of strong and gusty winds, and 
potentially higher seas.

High pressure just N of the area will shift southeastward to 
near 33N through Wed, and strengthen the pressure gradient 
modestly across the local area tonight through Thu. Cross- 
equatorial swell will raise seas along the equator and E of 120W
to 7 to 8 ft through Wed evening. Moderate to fresh winds are 
expected in the trade wind zone through Fri. The high pressure 
will weaken just N of the area on Sat to produce diminishing 
winds and seas through Sun, before a new cold front enters the NW
waters late Sun.
