Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Mon Apr 27 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
0230 UTC.

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

A trough axis extends from the Gulf of Papagayo at 10N86W to
13N95W to 11N110W. The ITCZ extends from 11N110W to beyond 
07N140W. A second ITCZ is south/southwest of the discussion 
waters. Scattered moderate and isolated strong convection is 
active from 10N to 12N between 105W and 110W, from 09N to 11N
between 115W and 125W, and from 11N to 13N between 127W and 133W.

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

Weak ridging off Baja California following a cold front is 
supporting moderate to fresh northwest winds over the offshore 
waters of Baja California, with gentle to moderate winds 
elsewhere. Combined seas are 5-7 ft off Baja California, 3-5 ft 
off southwest and southern Mexico, and 1-3 ft in the southern 
Gulf of California.

For the forecast, the weak ridging will build over the area through early
week. The pattern will support moderate to fresh northwest winds
over the Baja California waters, except for moderate to fresh to
occasionally strong winds funneling along the coast of Baja
California Sur between between Cabo San Lazaro and Punta Eugenia
tonight through Mon morning. Elsewhere, mostly light to gentle
west to northwest winds are expected through the week. Moderate
to fresh winds may develop in the central and southern Gulf of
California by the middle of the week as the pressure gradient
tightens slightly, then fresh to strong in the central Gulf of
California Thu night as a cold front moves through the area.
Seas may build to locally rough off Baja California Norte by the
end of the week in NW swell. 

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

Light to gentle variable winds prevail north of the Equator.
Gentle to moderate SE winds prevail south of the Equator. Seas
are 3-4 ft N of 08N, and 5-7 ft in S to SW swell S of 08N.

For the forecast, a light gradient will maintain rather tranquil
conditions over the Central American and Colombian waters
through the week while moderate to fresh southeast winds and
moderate long-period south to southwest swell remain offshore
Ecuador. Winds may pulse to moderate to fresh in the Gulf of
Papagayo Tue evening.

...REMAINDER OF THE AREA...

The ridge north of the ITCZ is disrupted by a trough extending 
from 29N123W to 20N130W. Moderate to locally fresh NE winds are
found north of the ITCZ to 20N west of 120W. Gentle to moderate 
winds are west of the trough. Mainly light to gentle winds are 
elsewhere across the open waters. Seas are 6-8 ft in mixed SE and
NW swell south of the Equator, and 4-7 ft across the remainder 
of the waters.

For the forecast, the rather weak high pressure across the 
region along with persistent troughing over the northwest waters 
will generally maintain moderate to occasionally fresh trade 
winds from the ITCZ to 20N and west of 120W. Combined seas will 
be in the range of 5-7 ft over the western part of the area 
through the remainder of the weekend then 4-6 ft across the 
entire area early next week, except near 8 ft along 03.4S into 
the early part of the week. Seas may build slightly over the 
waters north of 10N and west of 120W by the middle of the week 
in new swells.
