For the eastern North Pacific...east of 140 degrees west longitude:
1. Showers and thunderstorms remain disorganized in association with
a broad low pressure area located about 1500 miles southwest of the
southern tip of the Baja California peninsula. Some slow
development of this system is possible during the next couple of
days before upper-level winds become too strong for development.
This system is expected to move westward at 15 to 20 mph and cross
into the Central Pacific basin late this weekend.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...30 percent.
2. A large area of disturbed weather is located several hundred miles
southwest of Acapulco, Mexico. Environmental conditions appear
conducive for gradual development of this system, and a tropical
depression could form early next week. This disturbance is expected
to move west-northwestward 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. An 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 westward or west-northwestward well south
of Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...40 percent.
