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 0000 UTC surface analysis and satellite imagery through
0300 UTC. 
  
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... 

The monsoon trough extends from 08.5N79W to 10N86W to 09N85W to
11N104W to 09N115W. The ITCZ extends from 09N115W to 06N130W to
07N140W. Scattered moderate isolated strong convection is noted
from 07N to 15N between 87W and 107W. 

...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A ridge west of the area will support moderate to fresh 
northwest breeze west of the Baja Peninsula through late Sun, 
with moderate conditions developing again during the middle of 
next week. A moderate to locally fresh northwest breeze will 
prevail over the central and southern Gulf of California through 
late tonight. 

Surface low pressure will gradually develop along the monsoon 
trough near 11N100W this weekend. The low will move west- 
northwest with the potential for gradual development. This low 
has a high probability of developing into a tropical cyclone. 
Please refer to the latest eastern North Pacific Tropical Weather
Outlook under WMO/AWIPS headers ABPZ20 KNHC/MIATWOEP for 
additional information. 

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

Moderate to locally fresh nocturnal drainage flow is forecast 
across and downstream of the gulf of Papagayo through Mon night, 
with moderate nocturnal offshore breezes expected to resume on 
Tue night. The monsoon trough extends east to west between 08N 
and 10N, with gentle to moderate E winds forecast elsewhere north
of the monsoon trough and gentle to moderate southwest winds 
forecast south of the monsoon trough.
  
REMAINDER OF THE AREA...
   
A surface ridge extends across the northern waters. Fresh 
trades, and 6 to 8 ft seas, are expected to continue across the 
tropics south of the ridge, generally from 09N to 17N west of 
125W through Mon.

Northerly swell will propagate into the northern waters early
next week. Seas 8 ft or greater associated to this swell will
spread south to along 27N between 118W and 126W late Tue before 
beginning to subside. Seas are expected to subside below 8 ft 
west of 121W on Wed night.
