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

The National Hurricane Center is issuing advisories on Tropical
Depression Norma, located a few hundred miles west-southwest of the
southern tip of the Baja California peninsula.  The National
Hurricane Center has issued the last advisory on Post-Tropical
Cyclone Otis, located more than 1000 miles west of the southern tip
of the Baja California peninsula.

A broad area of low pressure located a few hundred miles southeast
of Acapulco, Mexico, is producing disorganized showers and
thunderstorms.  Environmental conditions appear conducive for
development of this system, and a tropical depression could form by
the weekend while it moves slowly west-northwestward near the coast
of Mexico.  Regardless of tropical cyclone formation, this system
could produce heavy rainfall along the southern coast of Mexico
during the next several days.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...60 percent.
