Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Thu Apr 30 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
1500 UTC.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A surface trough axis extends from 00N78W along the Panama coast
to 08N91W. An ITCZ extends from 08N91W to beyond 06N140W. Numerous
moderate and scattered strong convection is noted from 04N-10N
between 117W-135W. Scattered moderate and isolated strong
convection is noted north of 04N and east of 81W. Scattered
moderate convection is seen from 05N-07N between 95W-102W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
A surface ridge extends southeastward from 30N128W to 20N115W to
15N110W. Winds are NW moderate to fresh west of the Baja
California peninsula and over the central and S Gulf of
California. Elsewhere, winds are moderate or weaker. Seas are 5-6
ft in NW swell west of the Baja California peninsula, 3-5 ft in
mixed swell south of S Mexico, and 1-4 ft over the Gulf of
California.
For the forecast, surface ridging over the Pacific with lower
pressure over NW Mexico/SW United States will maintain fresh NW
winds over waters on both sides of the Baja California peninsula
through early Fri morning. Beginning Sat night, a Gulf of
Tehuantepec gap wind event will occur. Near-gale N winds are
forecast during Sun, with gale-force winds being possible.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND
WITHIN 750 NM OF ECUADOR...
Fresh NE winds are occurring over the Gulf of Papagayo region
with seas 5-6 ft this morning. Elsewhere winds are moderate or
weaker with seas 4-6 ft in S swell.
For the forecast, fresh NE to E winds will pulse in the Papagayo
region through Fri morning. Elsewhere, quiescent conditions
should prevail through early next week.
...REMAINDER OF THE AREA...
A surface ridge extends southeastward from 30N128W to 20N115W to
15N110W. The pressure gradient between the ridge and lower
pressure over the ITCZ is forcing moderate to fresh NE trades
north of 09N. Elsewhere winds are moderate or weaker. Seas are
8-9 ft from 18N-23N west of 133W in mixed N swell and wind waves.
Elsewhere seas are 5-7 ft in mixed swell.
A weakening pressure gradient will gradually diminish the trade
wind strength and extent through the weekend. A N to NW swell
will continue to combine with wind waves to cause 8-10 ft seas
from 10N-20N west of 130W through the weekend.
