California Peninsula.

Shower and thunderstorm activity has increased in association with a
trough of low pressure located a few hundred miles off the coast of
southern and southwestern Mexico. Environmental conditions appear
conducive for gradual development, and a tropical depression is
likely to form by the weekend while the system moves generally
west-northwestward, remaining parallel to but offshore of the
southwestern coast of Mexico. Interests along the southwestern coast
of Mexico should monitor the progress of this system.

* Formation chance through 7 days...high...90 percent.
