Tropical Weather Discussion for the eastern Pacific Ocean from
the Equator to 32N, east of 140W. The following information is
based on satellite imagery, weather observations, radar, and
meteorological analysis.

Based on 1200 UTC surface analysis and satellite imagery through
1530 UTC.

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

A surface trough extends from 09N83W to 05N95W to 06N102W. The 
intertropical convergence zone continues from 06N102W to 07N130W
to beyond 05N140W. Scattered moderate to isolated strong 
convection is noted within 210 nm north of the ITCZ between 110W
and 130W. 

...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Fresh to strong winds are noted off the coast of Baja California
Norte ahead of a cold front approaching from the west. The front
will dissipate by Mon as it moves through Baja California Sur 
and the southern Gulf of California. Long period NW swell in 
excess of 8 ft will persist off Baja California through early 
next week. Looking ahead, fresh to strong winds are possible in 
the Gulf of Tehuantepec by Wed as a cold front moves into southern
Mexico. 

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

Light to gentle winds are expected through the forecast period. 
Seas in the 2-4 ft range will prevail, except south of 05N where 
southerly swell will build seas to 4-6 ft today. Fresh gap winds 
are possible in the Gulf of Papagayo by mid week. 

REMAINDER OF THE AREA... 

A decaying NW swell is propagating across the northern part of
the forecast waters. Swell to 8 ft is observed in a recent
altimeter pass near 30N135W. The swell will decay below 8 ft
later today. 

Elsewhere mainly light to gentle winds prevail north of 15N, with 
moderate to occasionally fresh trades farther south. Looking 
ahead, a cold front will move into the waters north of 25N early
next week, accompanied by larger NW swell, with seas peaking 10 
to 15 ft over the waters north of 25N and west of 130W waters 
Tue. NW swell of 8 to 11 ft will cover the region north of 15N 
and west of 130W through mid week.
