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

The National Hurricane Center is issuing advisories on newly formed
Tropical Depression Thirteen-E, located several hundred miles south
of the southern tip of Baja California.

1. A tropical wave located about 1500 miles west-southwest of the
southern tip of the Baja California peninsula continues to produce
disorganized showers and thunderstorms.  As the tropical wave moves
slowly westward at 5 to 10 mph during the next couple of days, slow
development is possible, with upper-level winds becoming less
conducive for development thereafter.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...20 percent.

2. Another tropical wave is located a few hundred miles southwest of
Acapulco, Mexico, producing an area of disorganized showers and
thunderstorms. Some slow development of this system is possible
over the next several days as it moves west-northwest at 5 to 10
mph.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.

3. An area of low pressure is expected to form west of the coast of
Central America over the weekend.  Development of this system
is becoming increasingly likely, and a tropical depression could
form early next week while it moves westward well south of the
southern coast of Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...50 percent.
