Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Sun Apr 12 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
0200 UTC.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A surface trough extends from 10N75W to 01N83W to 03N93W. The
ITCZ extends from 03N95W to 08N136W to beyond 06.5N140W.
Scattered moderate isolated strong convection is occurring from
01N to 05N between 82W and 93.5W, from 03N to 07.5N between 94W
and 116W, and from 05N to 10N between 131W and 140W. Scattered
moderate convection is S of 03S between 87W and 106W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
A very weak surface ridge extends eastward into the waters of
Baja California, to the south of a cold front approaching the
region. This pattern is supporting light to gentle NW to N winds
across the waters of Baja, except for moderate NW winds between
Punta Eugenia and Cabo San Lazaro. Gentle N to NE winds then
extend beyond the Revillagigedo Islands. Moderate seas to 5 ft in
mixed NW and SW swell prevail across these waters. Light to
gentle winds are in the Gulf of California with slight seas,
except in northern portions where fresh SW gap winds have
recently developed. Farther E, gentle to locally moderate NW
winds prevail across the waters from Cabo Corrientes to Puerto
Angel. Strong N winds have increased across the Tehuantepec
region this evening and extend offshore to 15N. Seas are 6 to 8
ft there. An upper level trough shifting eastward into the area
now extends from Baja Sur northward into NW Mexico, with
associated clouds and showers now across interior Mexico.
For the forecast, gentle to moderate NW winds and moderate seas
are expected off Baja California through Mon, before winds
freshen modestly as high pressure gradually strengthens across
the region through midweek. Fresh to strong SW to W gap winds
are expected in the northern Gulf of California tonight through
Mon night, ahead of a couple of weak frontal boundaries that will
approach Baja California Norte. Seas will build up to 5 or 6 ft
with these winds. Elsewhere between Baja and Puerto Angel, winds
will be moderate or weaker with moderate seas through the middle
of next week. Pulsing fresh to strong northerly gap winds will
prevail across and downwind of the Tehuantepec region through
early Mon morning, with seas building up to 9 ft during the early
mornings. Afterwards, mainly moderate and variable winds are
expected through midweek.
....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 88.5W, producing rough seas of
7 to 8 ft. Moderate to fresh N to NE winds and moderate seas of 4
to 6 ft in SW swell prevail in the Gulf of Panama, and extend
beyond the Azuero Peninsula to 04N. Light to gentle winds and
moderate seas 4 to 5 ft in SW swell dominate the remainder of
the offshore forecast waters. Scattered moderate convection
extends from near the coast of western Panama southward and well
offshore.
For the forecast, fresh gap winds are expected to pulse to strong
during the nighttime and early morning hours across the Papagayo
region and downwind to 90W through Tue, as broad high pressure
continues to dominate the NW Caribbean. Winds up to 30 kt, and
seas up to 9 ft are forecast tonight and again Sun night. 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 7 ft between Ecuador
and the Galapagos Islands Tue through Wed. Pulses of active
convection will continue across the waters S of 09N through Mon,
and will propagate westward.
...REMAINDER OF THE AREA...
Weak high pressure NW of the area extends a ridge southeastward
through 30N140W and into the area to near 123W, south of an
approaching cold front along 31N. A broad upper level trough
continues across the area N of 18N between 110W and 125W, with
associated clouds and weather recently shifting inland across
interior NW Mexico. The pressure gradient between the ridge and
lower pressures in the vicinity of the ITCZ supports moderate to
fresh winds N of the ITCZ to about 14N between 95W and 128W, and
south of 22N to the west of 128W. Moderate seas in mixed NW and
S swell generally prevail across the area waters, with seas near
8 ft within the trade wind zone between 95W and 115W.
For the forecast, a broad and weak high pressure ridge will
dominate the weather pattern across the northern forecast waters
through early Mon, with little change in winds and seas, before
the high shifts southeast Mon through midweek to strengthen the
pressure gradient modestly. Moderate winds are expected in the
trade wind zone W of 95W through Mon. On Sun, a weakening cold
front will enter the northern waters W of 125W, and move into the
Baja Norte early Mon then across northern Gulf California late
Mon. Moderate N winds and moderate seas 7 to 8 ft in NW swell are
forecast in the wake of the front.
