For the eastern North Pacific...east of 140 degrees west longitude:
An area of disturbed weather is located near the southwestern
coast of Mexico. Although shower and thunderstorm activity is
showing some signs of organization, the system currently lacks a
closed surface circulation. Environmental conditions are expected
to be favorable for gradual development, and a tropical depression
is likely to form near the southwest coast of Mexico during the next
couple of days as the system drifts west-northwestward. Regardless
of tropical cyclone formation, heavy rains are expected over
portions of southwestern Mexico during the next several days.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.
