Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 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 1800 UTC surface analysis and satellite imagery through
2115 UTC.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A trough axis extends from low pressure over northwest Colombia
southwestward to the coast at 07N78W to 08N85W to 07N92W to
08N97W to 06N104W, where it transitions to the ITCZ to 05N110W
to 05N122W. It resumes at 04N128W to beyond 03N140W. Scattered
moderate convection is from 05N to 09N between 83W-87W, also
within 120 nm north of the ITCZ between 103W-108W and between
116W-122W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
A ridge axis extends from 30N127W southeastward to 25N120W and
to near 19N110W. 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 offshore the Baja California waters as
noted in a recent scatterometer satellite data pass. Seas over
these 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, the high pressure over the region will
generally maintain the moderate to fresh northwest winds over
the Baja California waters, with little change in conditions
expected into early next week. Northwest swell offshore Baja
California will subside a little tonight allowing for 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 trades north
of 20N and west of 123W. Decaying northwest swell along with wind
generated waves is producing seas of 8 to 9 ft as detected by
earlier altimeter satellite data accompany an area of moderate to
fresh trades over the waters from 02N to 21N west of about 120W.
Elsewhere, moderate or lighter winds and moderate seas remain
prevalent.
A weak trough is analyzed from near 10N122W to 06N124W and to
near 01N125W. Latest scatterometer satellite data indicates
moderate to fresh northeast winds between the trough and 135W.
Isolated showers and thunderstorms are noted from 06N to 11N
between 118W-127W.
For the forecast, rather weak high pressure across the region
will generally maintain moderate to fresh trade winds from the
ITCZ to 20N and W of 120W. Once the aforementioned northwest
swell decays, seas will be in the range of 6 to 7 ft over the
western part of the area through Sat, then 5 to 6 ft across
the entire area into early next week.
