NWS National Hurricane Center Miami FL
2205 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 1800 UTC surface analysis and satellite imagery through
2130 UTC.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

A surface trough axis extends from 07N78W along the Panama coast
to 07N99W. An ITCZ extends from 08N100W to beyond 08N140W. 
Numerous moderate and scattered strong convection is noted from
03N-10N between 117W-134W. Scattered moderate and isolated strong
convection is noted from 03N-06N east of 100W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A surface ridge extends southeastward from 30N128W to 20N115W to
15N108W. Winds are NW moderate to fresh west of the Baja 
California peninsula. Elsewhere, winds are moderate or weaker. 
Seas are 5-7 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, beginning Sat night, a Gulf of Tehuantepec gap
wind event will occur. Gale-force N winds are forecast during 
Sun. The event should quickly diminish by Mon. Surface ridging 
over the Pacific with lower pressure over NW Mexico/SW United 
States will maintain fresh to locally strong NW winds over waters
on both sides of the Baja California peninsula through tomorrow 
morning. Looking ahead, a surface trough will promote S to SW 
fresh to strong winds over the N Gulf of California Sun afternoon
and night.

....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND 
WITHIN 750 NM OF ECUADOR...

Winds are moderate or weaker with seas 4-6 ft in S swell over
forecast waters. Scattered moderate and isolated strong
convection is noted from 03N-06N east of 100W.

For the forecast, fresh NE to E winds will pulse in the Papagayo
region through early morning morning. Elsewhere, quiescent 
conditions should prevail through early next week. 

...REMAINDER OF THE AREA...

A surface ridge extends southeastward from 30N128W to 20N115W to
15N108W. 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-22N west of 134W 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 early next week. 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.
