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

1. Showers and thunderstorms associated with a broad area of low
pressure are located a little more than 1500 miles west-southwest of
the southern tip of the Baja California peninsula.  The shower
activity has not become any better organized today, and the system
is heading toward unfavorable upper-level winds. The low is expected
to move westward at 15 to 20 mph and cross into the Central Pacific
basin late this weekend or Monday with no significant development.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.

2. Another area of disturbed weather is located several hundred miles
south-southwest of Manzanillo, Mexico. Although this system is not
showing any signs of organization at this time, conditions are
forecast to become favorable for development and a tropical
depression could form early next week.  This disturbance is expected
to move toward the west-northwest at 15 to 20 mph during the next
several days.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...medium...60 percent.

3. And yet another area of low pressure is likely to form early next
week several hundred miles south of the southern coast of Mexico.
Environmental conditions appear to be conducive for gradual
development of this system while it moves toward the west or
west-northwest well south of Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...40 percent.
