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

A tropical wave located a few hundred miles south of Acapulco is
producing disorganized showers and thunderstorms. Environmental
conditions are forecast to become more conducive for gradual
development, and a tropical depression could form over the weekend
or early next week. This disturbance is forecast to move westward to
west-northwestward at 10 to 15 mph, well south of the coast of
Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...40 percent.

Disorganized showers and a few thunderstorms continue in
association with a low pressure area centered about 1300 miles
southwest of the southern tip of the Baja California peninsula.
Upper-level winds appear to be conducive for further development,
and a tropical depression could form during the next two or three
days while the disturbance moves west-northwestward or northwestward
at 10 to 15 mph. After that time, cool water temperatures are
forecast to prevent development.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...medium...40 percent.
