Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 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 0600 UTC surface analysis and satellite imagery through
0830 UTC.
..SPECIAL FEATURES...
Tropical Storm Genevieve is centered near 23.9N 137.3W at
02/0900 UTC, moving west-northwest at 11 kt. Estimated minimum
central pressure is 1003 mb. Maximum sustained wind speed is 45
kt with gusts to 55 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
today. The system is forecast to become post- tropical by early
this 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 100W, 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 122W, 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 10N121W to 08N126W.
The ITCZ continues from 08N126W to 08N140W. Scattered moderate
and isolated strong convection is noted from 04N to 13N between
88W and 103W, from 03N to 10N between 103W and 120W, and from 05N
to 10N between 120W and 140W.
..OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Moderate to fresh winds are over the northern Gulf of
California. Gentle to moderate winds prevail elsewhere 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 tonight 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, moderate to fresh winds will pulse across the
Papagayo region through the week. 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 fresh to
strong NE winds to the northwest of Genevieve. Seas in this
region are in the 8 to 10 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 24.5N 139.0W this afternoon, then become post- tropical
west of the area near 25.4N 141.2W 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.
