DISCUSSION AND OUTLOOK
----------------------
At 800 PM PDT (0300 UTC), the center of Tropical Storm Sergio was
located near latitude 17.5 North, longitude 125.6 West. Sergio is
moving toward the east-northeast near 12 mph (19 km/h).  An east-
northeastward to northeastward motion with a further increase in
forward speed is expected during the next few days.  On the forecast
track, the center of Sergio will approach the Pacific coast of Baja
California Sur on Friday.

Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts.  Gradual weakening is forecast during the next several days.

Tropical-storm-force winds extend outward up to 140 miles (220 km)
from the center.

The estimated minimum central pressure is 991 mb (29.27 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Through Sunday, heavy rainfall with Sergio is expected to
lead to storm total accumulations of 3 to 5 inches with local
amounts to 10 inches in northern Baja California Sur and Sonora in
Mexico and well as the Southern Plains and the Ozarks of the United
States.  This could lead to life-threatening flash flooding and
mudslides within mountainous terrain.

SURF:  Swells generated by Sergio will begin to affect much of the
Baja California Peninsula later today.  These swells are likely to
cause life-threatening surf and rip current conditions.  Please
consult products from your local weather office.
