Tropical Weather Discussion
NWS National Hurricane Center Miami FL
2205 UTC Wed Apr 8 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
2100 UTC.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A surface trough extends from 09N84W to 06N97W. The ITCZ continues
from 06N97W to 06N120W to 02N140W. A second ITCZ is south of the
Equator and runs from 02S106W to beyond 05S140W. Scattered moderate
to isolated strong convection can be found from 01N to 08N E of
84W to the coast of Colombia. A cluster of similar convective
activity is seen from 02N to 05N between 125W and 130W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Moderate to fresh N winds are noted across the Gulf of Tehuantepec
along with seas of 5 to 7 ft. Otherwise, a weak ridge continues
to dominate the offshore waters of Baja California supporting
gentle to moderate NW to N winds with moderate seas. However, mainly
moderate NW winds are observed in the vicinity of Cabo San Lucas
and downstream to near 22N. Light and variable winds are observed
across most of the Gulf of California, with the exception of light
to gentle SE to S winds near the entrance to the Gulf. Elsewhere
across the Mexican offshore waters, light to gentle winds and
moderate seas, primarily in southerly swell, prevail.
For the forecast, pulsing fresh to strong northerly winds are forecast
in the Tehuantepec region through Sun, with seas building up to 7
or 8 ft. Afterwards, gentle to moderate winds are expected. Moderate
to locally fresh NW winds and moderate seas are forecast off Baja
California through Mon under the influence of a ridge. By Mon night
into Tue, the pressure gradient may tighten enough between the ridge
to the W and lower pressures inland Mexico to support moderate to
fresh NW winds off the Baja California Peninsula. Fresh to strong
SW winds may briefly develop in the northern Gulf of California Fri
night ahead of a cold front approaching Baja California Norte, then
moderate to fresh SW to W winds are expected through the upcoming
weekend. Elsewhere, winds will be moderate or weaker with moderate
seas through the next several days.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
Recent scatterometer pass indicates moderate to fresh gap winds
across the Gulf of Papagayo and downwind to near 89W. Seas are 4
to 6 ft with these winds. Farther east, gentle to moderate N winds
and 3 to 4 ft seas are present in the Gulf of Panama and just south
of the Azuero Peninsula to near 04N. Light to gentle winds and
moderate seas dominate the remainder of the offshore forecast
waters. Stronger winds are noted in scatterometer data offshore
Colombia due to convective activity.
For the forecast, fresh to locally strong gap winds are expected
during the nighttime and early morning hours in the Papagayo
area and downwind to about 89W through Thu. Toward the upcoming
weekend, winds may increase to 30 kt with seas building to 8 or 9
ft in the Papagayo region as a stronger high pressure settles N
of the area. Moderate northerly winds, occasionally fresh, are
forecast in the Gulf of Panama throughout the forecast period,
with stronger conditions most likely during the upcoming weekend.
Light to gentle winds and moderate seas will prevail elsewhere.
...REMAINDER OF THE AREA...
A stationary front extends from 31N130W to 27N140W. Gentle to
locally moderate N winds and moderate seas are behind the front.
A band-like of multilayer clouds, associated with strong upper
level winds, is noted south of the front entering the forecast
waters near 21N140W. A 1020 mb high pressure center is ahead of
the front located near 28N125W and extends a ridge across the
remainder of the N waters, particularly N of 19N and W of 110W.
The pressure gradient between the ridge and lower pressures in
the vicinity of the ITCZ supports moderate to locally fresh winds
in the trade wind zone, W of 120W. Seas of 5 to 7 ft are within
these winds. Elsewhere, moderate or weaker winds and moderate
seas are occurring.
For the forecast, the front will move eastward across the waters
N of 20N while dissipating by Fri. Gentle to locally moderate
winds will follow the front along with seas 6 to 7 ft. The high
pressure center located ahead of the front will dissipate on Thu,
then, the high pressure following the front will take control of
the weather pattern across the forecast waters over the next
several days.
