RAINFALL:  Sergio is expected to produce total rain accumulations
of 3 to 5 inches, with isolated maximum amounts of 8 inches over
northwestern Mexico. This rainfall could cause life-threatening
flash flooding and mudslides in mountainous terrain.

Moisture from Sergio will affect the United States, with total
rain accumulations of 1 to 3 inches from southeast Arizona and
southern New Mexico toward the southern Plains through Saturday.
This rainfall could cause life-threatening flash flooding.

WIND:  Tropical-storm-force wind gusts are still occuring
primarily to the north and east of the track of Sergio. These winds
will continue to diminish today.

SURF:  Swells generated by Sergio could still affect much
of the Baja California peninsula today and the Sea of Cortez, likely
