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

1. Satellite imagery indicates that a low pressure system located over 
1400 miles east-southeast of the Hawaiian Islands is showing signs 
of better organization this morning, with increased shower and 
thunderstorm  activity mainly to the north of its center.  
Environmental conditions are expected to be conducive for further 
development, and a tropical depression is likely to form within the 
next day or so while the system moves westward at 10 to 15 mph.  By 
Tuesday, cooler waters and unfavorable upper-level winds will likely 
limit any further development of this system.

* Formation chance through 5 days...high...70 percent.

2. An area of low pressure could form in several days a few hundred 
miles south or southeast of the Gulf of Tehuantepec.  Thereafter, 
some gradual development is possible through late this week while 
the system moves generally west-northwestward at 10 to 15 mph, 
remaining a couple of hundred miles offshore of the coast of 
southern Mexico. 
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.
