Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Thu Apr 23 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 1200 UTC surface analysis and satellite imagery through
1545 UTC.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A trough axis extends from low pressure over northwest Colombia
southwestward to the coast at 07N78W to 06N85W to 07N95W to
06.5N104W, where it transitions to the ITCZ to 04N122W. Numerous
moderate convection is from 04N to 11N between 117W-122W.
Scattered moderate convection is within 180 nm south of the
trough between 85W-90W, also within 120 nm north of the of
the trough and ITCZ between 102W-106W, and within 60 nm south
of the trough between 96W-99W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
A ridge axis extends from 30N127W southeastward to 25N120W and
to near 19N108W. High pressure covers the area north of 15N west
of about 115W. The pressure gradient between the ridge and a
trough along the Gulf of California is supporting moderate to
fresh northwest winds across the Baja waters north of Cabo San
Lucas. Seas across the Baja California offshore waters are
6 to 8 ft in northwest swell. Elsewhere, winds are light to
gentle along with seas of 4 to 6 ft in long-period south swell,
except for lower seas of 2 to 4 ft in the Gulf of California.
For the forecast, high pressure will continue to build across
the area through Friday generally maintaining moderate to fresh
northwest winds over the Baja California waters, and with little
change expected through the weekend. The northwest swell offshore
Baja California will subside a little by tonight allowing for
the seas to lower to just below 8 ft. Elsewhere, mostly light to
gentle west to northwest winds are expected through Mon.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND
WITHIN 750 NM OF ECUADOR...
Moderate northeast to east gap winds are in the Gulf of Papagayo
region along with seas of 3 to 5 ft. These winds reach westward
to near 88W. Elsewhere, light to gentle variable winds prevail.
Moderate seas in long-period southwest swell will slowly
subside today.
For the forecast, a light gradient will maintain rather tranquil
conditions over Central American and the equatorial waters
through early next week. Seas are forecast to slightly build over
the waters between Ecuador and the Galapagos Islands beginning
on Fri night.
...REMAINDER OF THE AREA...
The pressure gradient associated to high pressure over this part
of the region is generally sustaining light to gentle anticyclonic
winds north of 20N and west of 123W. Decaying northwest swell
producing seas of 8 to 9 ft accompany an area of moderate to
fresh trades over the waters from 02N to 20N west of about 120W.
Elsewhere, moderate or lighter winds and moderate seas remain
prevalent.
For the forecast, rather weak high pressure across the region
will generally maintain moderate to fresh trade winds S of 20N
to the ITCZ and W of 120W. Once the aforementioned northwest
swell decays, seas will be around the range of 6 to 7 ft over
the western part of the area through Sat and 5 to 6 ft elsewhere
through Mon.
