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

1. South of Southwestern Mexico (EP90):
An area of low pressure located a few hundred miles offshore of the 
southwestern coast of Mexico is producing showers and thunderstorms 
that have become better organized since yesterday. Environmental 
conditions are conducive for further development of this system, and 
a tropical depression is very likely to form within the next day or 
so. This system is expected to move slowly westward and then turn 
northwestward late in the week offshore of the coast of southwestern 
Mexico. Additional information on this system, including gale 
warnings, can be found in High Seas Forecasts issued by the National 
Weather Service.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 7 days...high...90 percent.

2. South of Guatemala and Southern Mexico:
An area of low pressure is expected to form south of the coasts of 
Guatemala and southern Mexico in a few days. Gradual development of 
the disturbance will be possible, and a tropical depression is 
likely to form late this week or over the weekend while the system 
meanders over the far eastern portion of the basin.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...high...70 percent.
