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

1. Satellite-derived winds and surface observations indicate that an
elongated low pressure system is located about 100 miles south of
the Mexico-Guatemala border.  Although associated showers and
thunderstorms remain disorganized, environmental conditions are
expected to be conducive for additional development, and a tropical
depression or a tropical storm is likely to form during the next
day or two. The system is forecast to move generally toward the
west-northwest at 10 to 15 mph for the next several days, near or
just offshore the coast of southern Mexico.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

2. A weak and nearly stationary area of low pressure located about
900 miles south-southwest of the southern tip of the Baja California
peninsula continues to produce disorganized shower activity.  Any
development should be slow to occur while the system drifts
northward or north-northeastward during the next several days.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.
