Tropical Weather Discussion

NWS National Hurricane Center Miami FL

0405 UTC Mon Aug 3 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

0130 UTC.



...TROPICAL WAVES...



The axis of a tropical wave is near 83W, north of 02N, moving 

westward at 10 to 15 kt. Nearby convection is discussed in the 

ITCZ/Monsoon Trough section below.



The axis of a tropical wave is near 107W, moving westward at 

around 10 to 15 kt. Nearby convection is discussed in the 

ITCZ/Monsoon Trough section below.



The axis of a tropical wave is near 125W, from 02N to 18N, 

moving westward around 10 kt. Nearby convection is discussed in 

the ITCZ/Monsoon trough section below. 



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



The monsoon trough extends from 10N86W to 10N113W to 12N120W to

06N135W. The ITCZ extends from 06N135W to 06N140W. Scattered 

moderate and isolated strong convection is noted from 03N to 13N 

between 80W and 122W, and from 04N to 10N between 135W to 140W.



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



Gentle to moderate winds prevail across the region. Moderate 

seas dominate the open waters off Mexico, with slight seas in the

Gulf of California. 



For the forecast, the pressure gradient between high pressure 

west of the area and lowering pressure over the Colorado River 

Valley will support fresh SW winds and building seas over the 

northern Gulf of California through the early part of the week. 

Elsewhere, a moderate pressure gradient will support mostly 

gentle to moderate winds across the offshore waters of Mexico. 

Long- period NW swell over the waters off Baja California Norte 

will start to subside Tue. Fresh to strong gap winds and building

seas are expected across the Gulf of Tehuantepec toward the end 

of the week. 



...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, 

AND WITHIN 750 NM OF ECUADOR...



Moderate to locally fresh winds and moderate seas prevail over 

and downstream the Gulf of Papagayo. Gentle to moderate winds are

found between the Galapagos Islands and Ecuador. Light to gentle

winds and moderate seas are noted elsewhere. 



For the forecast, moderate to fresh winds will pulse across the 

Papagayo region tonight, and again by mid week with rough seas. 

Moderate or weaker winds and moderate seas in SW swell are 

expected across the remainder of the waters through the period. 



...REMAINDER OF THE AREA...



The remnant low of Genevieve is just crossing 140W. Strong to

near gale force winds around this remnant low are over the 

forecast waters N of 25N and W of 138W. Elsewhere over the

discussion waters, gentle to moderate winds and moderate seas 

prevail. 



For the forecast, large northerly swell off California will push

southward into the waters off Baja California Norte north of 27N

and east of 130W into early this week. New large southerly swell

may build south of the Equator and west of 100W beginning Tue 

night.
