Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Fri Apr 17 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 coastal Costa Rica near 09N83W to 
05N102W. The ITCZ begins at 05N102W to a 1008 mb low near
04N110W, then beyond 06N140W. Scattered moderate and isolated 
strong convection is occurring from 03N-07N between 103W-123W. 
Isolated moderate convection is also occurring from 00N-05N 
between 90W-103W and from 03N-10N between 127W-135W. A Southern 
Hemisphere ITCZ extends from 03S93W to 03S140W. Isolated moderate
convection is observed from 03S-07S between 86W-89W. 

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

A surface ridge extends from 30N127W to 20N117W to 15N110W. NW
winds west of the Baja California peninsula are moderate to
fresh. Elsewhere over the Pacific and the Gulf of California,
winds are moderate or weaker. Seas are 5-6 ft in NW swell over 
the Pacific NW of Cabo Corrientes, 5-6 ft in S swell over the
Pacific SE of Cabo Corrientes, and 1-2 ft over the Gulf of
California. No deep convection is occurring over the Mexican
offshore waters. 

For the forecast, developing low pressure over the SW United 
States will bring fresh SW winds to the N Gulf of California 
tonight before diminishing tomorrow. Fresh NW winds will also 
occur near Cabo San Lucas through tomorrow night. Additionally, 
large NW swell will impact the Pacific waters west of Baja 
California Norte tonight through Sat. Elsewhere, rather quiet 
conditions will remain over the Mexican offshores through the 
weekend. Looking ahead, high pressure building over the Gulf of 
America is expected to induce a strong to near gale Tehuantepec 
gap wind event Sun night into Mon night. 

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

Winds across the Central American and equatorial waters are
moderate or weaker with seas 5-6 ft in S swell. Isolated moderate
convection is occurring from 00N-05N between 90W-103W near the
Galapagos Islands.  

For the forecast, fresh E winds over the Gulf of Papagayo region
will diminish by Fri night. Showers and thunderstorms occurring 
near the Galapagos Islands should last into Fri night. Elsewhere,
expect rather tranquil conditions to remain over the Central 
American and the equatorial waters through early next week. 
 
...REMAINDER OF THE AREA...

A surface ridge extends from 30N127W to 20N117W to 15N110W. The 
weak pressure gradient between the ridge and lower pressure over 
the ITCZ is forcing only moderate to locally fresh NE trades over
forecast waters. Seas are 5-7 ft in mixed swell. No additional 
deep convection is occurring away from the surface trough/ITCZ.

For the forecast, little change is expected in the winds during
the next few days. Large NW swell will impact waters north of 
28N and east of 125W tonight through Fri night. Otherwise, 
little change in the seas are also expected through the weekend. 
Looking ahead, a cold front will reach our NW corner at 30N140W 
on Sun. The frontal boundary should move eastward while gradually
weakening, accompanied by large N to NW swell. The large N to NW
swell should reach to 20N west of 130W by Tuesday.
