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

The National Hurricane Center is issuing advisories on Hurricane
Kiko, located over the southwestern part of the basin.

1. Showers and thunderstorms remain limited in association with a
well-defined area of low pressure located about 650 miles
south-southwest of Manzanillo, Mexico.  Any significant increase in
the thunderstorm activity would lead to the formation of a tropical
depression later today or tonight, while the disturbance moves
west-northwestward or northwestward.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

2. Recent satellite-derived wind data indicate that the large area of
low pressure located a few hundred miles south-southeast of
Acapulco, Mexico, is becoming better organized.  If this development
trend continues, then a tropical depression or tropical storm could
form later today or tonight.  This system will continue to move
west-northwest near or just offshore of the coast of Mexico for the
next few days.  Interests along the southwestern coast of Mexico
should monitor the progress of this system.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

3. Disorganized cloudiness and showers near and just west of Central
America are associated with a tropical wave.  Gradual development of
this system is possible during the next several days while the wave
moves westward or west-northwestward at 5 to 10 mph.  Locally heavy
rainfall is possible along the coasts of El Salvador, Guatemala
and southeastern Mexico during the next few days.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...30 percent.
