Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Thu Jul 9 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
0300 UTC.

...TROPICAL WAVES...

A tropical wave is analyzed along 89W to the north of 04N, 
moving westward at 10-15 kt. Convection is described below in the
Monsoon Trough/ITCZ section.

A tropical wave is analyzed along 110W, from 03N to 16N, moving 
westward at 10-15 kt. Convection is described below in the
Monsoon Trough/ITCZ section.

A tropical wave is analyzed along 137W from 02N to 16N, moving 
westward at around 10-15 kt. Convection is described below in the
Monsoon Trough/ITCZ section.
 
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

The monsoon trough extends from 08N84W to 07N95W to 10N115W to 
05N125W. The ITCZ is from 05N125W to 07N135W. Scattered moderate
isolated strong convection is active 03N to 07N east of 85W.
Scattered moderate convection is active from 06n to 12N between 
95W and 125W.

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

Fresh NW winds and 6-7 ft seas prevail off Baja California Norte
between high pressure west of the area and lower pressure over 
northwest Mexico. Farther south, fresh to strong N to NE gap 
winds are active across the Tehuantepec region, with 6-8 ft seas.
Gentle to moderate breezes and 4-6 ft seas are noted elsewhere, 
except 1-3 ft seas across the Gulf of California. 

For the forecast, fresh NW winds will continue off Baja California 
Norte through tonight, with rough seas in NW swell near Guadalupe
Island into Thu. These winds will diminish Thu, as low pressure 
moves off the Pacific into the lower Colorado River Valley. This 
will result in fresh to strong S winds and rough seas late Thu 
into Fri over the Gulf of California. Fresh to strong northerly 
gap winds will pulse in the Gulf of Tehuantepec through the week.
Lowering pressure across the tropical eastern Pacific will 
induce fresh to strong winds and rough seas offshore southern 
Mexico by the weekend.

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

Fresh NE to E gap winds persist across the Papagayo region and 
Nicaragua, extending offshore to near 90W. Seas are estimated to 
be 6-8 ft. Moderate to fresh winds are elsewhere to the N of 
08N. Moderate SE winds are across the offshore waters of the 
Galapagos Islands, where seas are 5-7 ft in SW swell. Light to 
gentle winds are across the remainder of the waters, along with 
4-6 ft mainly in SW swell.

For the forecast, fresh to strong NE-E gap winds will pulse in the
Gulf of Papagayo region through late Sun, mainly at night and
into the morning hours. Cross equatorial SW swell will move
through the waters off Ecuador and the Galapagos Islands through
tonight, with seas peaking around 9 ft. Gentle to moderate
breezes and slight to moderate seas will persist elsewhere.
Lowering pressure across the tropical eastern Pacific will
induce fresh to strong winds and rough seas offshore El Salvador
and Guatemala by Sun.  

...REMAINDER OF THE AREA...

A few thunderstorms are active along a surface trough, the 
remnant of Douglas, along 140W from 24N to 30N. Elsewhere, a 
broad ridge dominates the waters north of 15N, supporting 
moderate NE winds and 5-7 ft seas in a mix of N and SW swell. 
Fresh NE winds and seas 7-8 ft are also noted farther S near the 
tropical wave near 137W. Gentle to moderate breezes are noted 
elsewhere. Long period SW swell to 8 ft is reaching 04N between 
90W and 120W. Combined seas are mainly 5-7 ft elsewhere.

For the forecast, strong winds and rough seas will accompany the
tropical wave near 137W at it moves westward at 10-15 kt, past 
140W Thu night. Farther north, swell of 8-9 ft will persist 
north of 25N to the east of 125W into Fri. Farther south, large 
swell to 7-8 ft will persist south of 05N or so between 95W and 
120W through Fri.
