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.

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

A surface trough axis extends from 07N78W to 10N87W to 06N100W. 
The ITCZ extends from 06N100W to 10N121W to beyond 08N140W. 
Numerous moderate to scattered strong convection is seen near the
ITCZ from 08N to 12N between 118W and 135W. Scattered moderate 
convection is occurring near and south of the trough from 02N to 
07N between 79W and 94W...and from 02N to 06N between 110W and 
121W.

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

Ridging off Baja California combined with troughing over northwest
Mexico supports moderate to fresh NW to N winds and seas of 4 to
6 ft off the peninsula. Moderate NW winds with 3 to 4 ft seas 
have also developed across the southern Gulf of California, light
to gentle winds and seas at 1 to 2 ft dominate the rest of the
Gulf. Light to gentle winds with 4 to 5 ft seas in mixed moderate
swells prevail for the offshore waters of central and southern
Mexico.

For the forecast, a broad surface ridge building southeastward 
from a high west of the U.S. west coast will cause moderate to 
fresh NW to N winds west of Baja California Wed afternoon through
Thu night. In response, W to NW fresh to strong winds are 
expected in the Gulf of California Thu and Thu night. In the long
term, strong to near-gale force gap winds will impact the Gulf 
of Tehuantepec Sun through Mon.

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

Fresh to strong NE to E gap winds and seas of 4 to 6 ft are
present at the Papagayo region. Moderate to fresh N winds with 3
to 4 ft seas are noted at the Gulf of Panama. Gentle to moderate
SE to SW winds and 4 to 7 ft seas in moderate S swell are evident
at waters near the Galapagos Islands and off Ecuador. Light to
gentle winds with 2 to 4 ft seas prevail for the remainder
offshore waters in Central America, and off Colombia.

For the forecast, fresh with locally strong NE to E winds during
nighttime are anticipated to continue in the Papagayo region 
through Thu night. Northerly winds at the Gulf of Panama will 
pulse to fresh tonight and Wed night. Long-period S swell is 
going to maintain moderate seas near the Galapagos Islands and 
off Ecuador through Sat. 

...REMAINDER OF THE AREA...

Tightened gradient between a surface trough near 29N130W and a
broad surface ridge to the northwest is keeping moderate to fresh
NE to E winds and seas of 6 to 7 ft north of 22N and west of 
125W. Gentle to moderate with locally fresh NE to E winds and 5
to 7 ft seas are found north of the ITCZ to near 22N and west of
115W. Gentle with locally moderate E to SE winds are noted south
of the ITCZ. Seas are 6 to 8 ft in mixed SE and NW swell south 
of the Equator, and 4 to 7 ft elsewhere south of the ITCZ.

For the forecast, little change is expected into the weekend.
Moderate to fresh NE winds and moderate seas will prevail N of
the ITCZ, with gentle winds and moderate seas to the S.
