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 22.6N 131.4W at
01/0300 UTC, moving west-northwest at 13 kt. Estimated minimum
central pressure is 1000 mb. Maximum sustained wind speed is 45
kt with gusts to 55 kt. Peak seas are near 22 ft or 6.5 m.
Scattered moderate and isolated strong convection within 60 nm in
the NE semicircle. Scattered moderate convection is elsewhere
from 21N to 24N between 129W and 133W. Only slight weakening
is expected over the first 24 to 36 hours, then the system will
resume a steady weakening trend thereafter as it moves on a
west- northwest track over cooler waters. The system is forecast
to become post- tropical late this weekend.

western Caribbean, moving westward at around 5 to 10 kt. Nearby
convection is discussed in the ITCZ/Monsoon Trough section below.
The axis of a tropical wave is near 116W, 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 10N85W to 07N92W. The ITCZ
extends from 06N92W to 04N99W to 07N112W. Scattered moderate
and isolated strong convection is noted from 03N to 08N between
85W and 110W, from 06N to 15N between 110W and 120W, and from
04N to 10N between 120W and 126W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Moderate to fresh winds prevail over the Gulf of Tehuantepec.
Elsewhere, gentle to moderate winds prevail. 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 to strong SW winds and building seas
over the northern Gulf of California Sat night into Sun morning.
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, and
moderate seas 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 23.1N 133.4W Sat morning, 23.9N 136.1W Sat evening, 24.8N
138.8W Sun morning, then become post-tropical west of the area
near 25.8N 141.3W Sun evening. 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 by the end of the weekend into early next week. New large
southerly swell may build south of the Equator and west of 100W
beginning Tue night.
