DISCUSSION AND OUTLOOK
----------------------
At 200 PM PDT (2100 UTC), the center of Tropical Storm Sergio was
located near latitude 16.9 North, longitude 126.5 West. Sergio is
moving toward the east-northeast near 9 mph (15 km/h).  An east-
northeastward to northeastward motion with a faster forward speed is
expected during the next few days.  On the forecast track, the
center of Sergio will approach the Pacific coast of the Baja
California peninsula on Friday.

Maximum sustained winds have decreased to 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 990 mb (29.24 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Heavy rainfall associated with Sergio and its remnants is
expected to produce storm total accumulations of 3 to 5 inches with
local amounts to 10 inches in northern Baja California Sur and
Sonora in Mexico as well as the Southern Plains and Ozarks of the
United States through Sunday.  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 by Wednesday.  These swells are likely to
cause life-threatening surf and rip current conditions.  Please
consult products from your local weather office.
