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 
1500 UTC.

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

A surface trough extends from 06N77W to 03N102W.  The ITCZ 
extends from 03N102W to 08N140W.  Scattered moderate convection 
is within 60 nm of the trough axis between 95W and 100W.

...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...  

A 1005 mb low is just north of our area at 34N132W with a warm 
front extending southeastward to 28N122W where it joins a cold 
front that extends to northern Baja California.  Winds are fresh 
breeze or weaker associated with this frontal boundary.  To the 
southwest of the low a stronger cold front extends from 30N134W 
to 25N140W.  NW to N winds behind the front are up to strong 
breeze or near gale, as are the S to SW winds ahead of the 
front.  As the low and front progresses eastward, strong breeze 
SW winds will impact the zones west of Baja California Sat 
before diminishing Sun.  The NW to N winds behind the front will 
gradually diminish.  NW swell will reach up to a maximum of 15 
ft Sun along 30N before gradually diminishing.  Quiescent 
conditions should prevail thereafter until at least Wed.

Gulf of California: A cold front extends from NW Mexico across 
the northern Gulf of California and northern Baja California. 
Northerly winds behind the front are moderate breeze or weaker 
and the front is expected to dissipate by tomorrow.  A second 
strong cold front approaching will product strong breeze to near 
gale southerlies Sat night and Sun morning. Seas, however, 
should remain below 8 ft.  After the cold frontal passage Sun, 
winds throughout the Gulf will drop to fresh breeze or weaker 
through Wed.

Gulf of Tehuantepec: No significant gap wind events are expected 
in the Gulf of Tehuantepec through at least Wed.  Winds will 
remain fresh breeze or weaker and seas below 8 ft.

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

Gulf of Papagayo: A moderate surface pressure gradient over the 
western Caribbean Sea is supporting fresh to strong breeze NE 
winds are expected during the overnight and early morning hours 
through Wed. Seas should peak around 8 ft.

Gulf of Panama: Fresh N to NE winds will persist into the Gulf 
of Panama each night through Tue, possibly strengthening to 
strong breeze on Wed. Seas should peak around 8 ft.

REMAINDER OF THE AREA... 

A 1005 mb low is just north of our area at 34N132W with a warm 
front extending southeastward to 28N122W where it joins a cold 
front that extends to northern Baja California.  Winds are fresh 
breeze or weaker associated with this frontal boundary.  To the 
southwest of the low a stronger cold front extends from 30N134W 
to 25N140W.  NW to N winds behind the front are up to strong 
breeze or near gale, as are the S to SW winds ahead of the 
front.  As the low and front progresses eastward, strong breeze 
SW winds ahead of the front and the NW to N winds behind the 
front will gradually diminish.  NW swell will reach up to a 
maximum of 15 ft Sun along 30N before gradually diminishing. 
Quiescent conditions should prevail thereafter until at least 
Wed.
