Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Sat Aug 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 0000 UTC surface analysis and satellite imagery through
0350 UTC.

...TROPICAL WAVES...

A tropical wave is just S of Tehuantepec with axis near 94W, 
extending from 05N to 16N, and moving westward at 10 kt.
Scattered to isolated moderate convection from 03N to 15N between
92W and 103W. 

A tropical wave extends from 05N to 17N with axis near 111W, moving
westward at 10-15 kt. Numerous moderate to strong convection is
from 04N to 15N between 104W and 120W.

A tropical wave extends from 06N to 17N with axis near 132W,
moving westward at 15-20 kt. Scattered moderate to strong
convection is from 02N to 16N between 120W and 138W. 

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

The monsoon trough extends from 09N83W to 09N96W. The ITCZ begins
near 09N96W to 10N109W, then resumes near 09N115W to 09N129W,
then resumes near 09N134W to 09N140W. For information on
convection, see the Tropical Waves Section above. 

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

Fresh to strong winds and moderate to locally rough seas are 
over the Gulf of Tehuantepec. Moderate or weaker winds, and 
moderate seas, prevail elsewhere, except in the Gulf of
California where winds are light to gentle and seas are slight. 

For the forecast, fresh to strong gap winds and rough seas are 
expected across the Gulf of Tehuantepec into the weekend. 
Elsewhere, a moderate pressure gradient will support mostly 
gentle to moderate winds across the offshore waters of Mexico. 
The pressure gradient between high pressure NW of the area and 
lower pressure over the Colorado River Valley will support fresh 
southerly winds across the northern Gulf of California late this 
weekend into early next week. 

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

Fresh to near gale-force winds are across and downstream of the 
Gulf of Papagayo to nearly 89W. Seas of 7 to 8 ft accompany the 
plume of gap winds. In the Gulf of Panama, moderate to fresh N
winds extends to 06N. Moderate seas in the 4 to 5 ft are over
this region. Otherwise, moderate easterlies from the Papagayo gap
wind event extends across the Guatemala and El Salvador outer
offshores where seas are 5-6 ft. Elsewhere, light to gentle winds
prevail along with moderate seas in SW swell.  

For the forecast, fresh to strong gap winds and occasional rough
seas will pulse across the Gulf of Papagayo into early next 
week. Moderate or weaker winds and moderate seas in SW swell are 
expected across the remainder of the waters through the period, 
except for large SE to S swell near the Galapagos early next 
week. 

...REMAINDER OF THE AREA...

A 1027 mb high near 37N138W extends a ridge across the
subtropical E Pacific waters to nearly 115W. The gradient of
pressure between this area of high pressure and a tropical wave 
with axis near 132W is supporting moderate to fresh NE to E winds 
from 12N to 25N W of 130W. Seas over these waters are 7-8 ft. 
Rough seas to 8 ft are found over the waters S of 03N between 
113W and 128W. Elsewhere, gentle to moderate winds and moderate 
seas prevail.

For the forecast, seas to 8 ft in the western tradewind waters 
will subside by Sat. Farther south, southerly swell to 8 ft will
impact the waters south of 05N and west of 100W through the 
weekend. Otherwise, showers and thunderstorms associated with the 
tropical wave near 132W may further organize, likely resulting in
the development of a tropical depression early next week as this
system moves westward toward the central Pacific. Also, an area 
of low pressure could form well offshore of the SW coast of 
Mexico early or into the middle of next week. Some gradual 
development of this system is possible thereafter as it moves 
generally west-northwestward.
