Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Sun Aug 2 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
0230 UTC.

...SPECIAL FEATURES...

Tropical Storm Genevieve is centered near 23.5N 136.0W at
02/0300 UTC, moving west-northwest at 12 kt. Estimated minimum
central pressure is 1004 mb. Maximum sustained wind speed is 40
kt with gusts to 50 kt. Peak seas are near 17 ft or 5 m. Scattered
moderate and isolated strong convection is noted within 60 nm in
the NE semicircle. Genevieve will maintain a gradual weakening
trend while moving on a west- northwestward track through the
remainder of the weekend. The system is forecast to become post-
tropical by early next week.

Please read the latest HIGH SEAS FORECAST issued
by the National Hurricane Center at website -
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml and the latest
Genevieve NHC Forecast/Advisory and Public Advisory at
www.hurricanes.gov for more details.

...TROPICAL WAVES...

The axis of a tropical wave is near 99W, 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 121W, 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 09N78W to 09N106W to 12N121W to
10N127W. The ITCZ continues from 10N127W to 07N135W to 08N140W.
Scattered moderate and isolated strong convection is noted from
03N to 11N between 80W and 124W.

...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 next week.
Elsewhere, a moderate pressure gradient will support mostly
gentle to moderate NW winds across the offshore waters of Mexico.
Long- period NW swell will move into the waters off Baja
California Norte Sun night through then start to subside Tue.

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

Fresh to strong 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, fresh to strong NE to E gap winds will pulse
across the Papagayo region into Sun, with occasionally rough
seas. Moderate to fresh winds will then pulse thereafter.
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...

Please refer to the Special Features section for information on
Tropical Storm Genevieve.

For waters not impacted by Genevieve, high pressure is centered
just northwest of the area. The pressure gradient between the
area of high pressure and Genevieve is supporting moderate to
fresh NE winds to the northwest of Genevieve. Seas in this region
are in the 7 to 9 ft range. Gentle to moderate winds, and
moderate seas, prevail over the remainder of the discussion
waters.

For the forecast, the center of Tropical Storm Genevieve will
move to 24.3N 138.0W Sun morning, become post-tropical and move
west of the area near 25.2N 140.4W Sun evening, then weaken to a
remnant low near 26.1N 142.5W Mon morning. Away from Genevieve,
little change in marine conditions is forecast through the
weekend. Rough northerly swell off California is likely to push
southward into the waters off Baja California Norte north of 27N
and east of 130W into early next week. New large southerly swell
may build south of the Equator and west of 100W beginning Tue
night.
