For the eastern North Pacific...east of 140 degrees west longitude:

1. South of the Gulf of Tehuantepec:
Showers and thunderstorms remain disorganized in association with a 
surface trough located a few hundred miles south of the Gulf of 
Tehuantepec.  Environmental conditions are forecast to be conducive 
for gradual development, and a tropical depression is likely to 
form late this week or this weekend while the system moves 
west-northwestward or northwestward at 5 to 10 mph.  Interests in 
southern Mexico should monitor the progress of this system.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...high...80 percent.

2. Central portion of the eastern Pacific: 
A trough of low pressure located several hundred miles off the 
coast of southwestern Mexico continues to produce disorganized 
showers and thunderstorms. Environmental conditions could support 
some slow development during the next day or two while this 
system moves little.  Upper-level winds are forecast to become too 
strong for development late this week.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...20 percent.
