DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 500 AM MST (1200 UTC), the center of Hurricane Sandra was located
near latitude 19.3 North, longitude 108.9 West. Sandra is moving
toward the north-northeast near 12 mph (19 km/h), and this motion is
expected to continue during the next day or two.  On the forecast
track, the core of Sandra is expected to pass to the south of the
southern tip of the Baja California peninsula tonight or early
Saturday, and near the coast of the Mexican state of Sinaloa on
Saturday.  However, a small deviation of the track to the left could
bring stronger winds to extreme southern portions of the Baja
California peninsula.

Maximum sustained winds have decreased to near 100 mph (160 km/h)
with higher gusts.  Rapid weakening is forecast during the next day
or so, and Sandra is forecast to weaken to a tropical storm during
the next 24 hours, and become a remnant low on Saturday.

Hurricane force winds extend outward up to 35 miles (55 km) from the
center and tropical storm force winds extend outward up to 160 miles
(260 km).

The estimated minimum central pressure is 972 mb (28.70 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Tropical storm conditions are possible within the watch area
tonight and Saturday morning.

RAINFALL:  Sandra is expected to produce total rain accumulations of
4 to 6 inches with isolated maximum amounts of 12 inches over the
Mexican states of Baja California Sur, Sinaloa, Sonora, Chihuahua,
and far western Durango through Saturday night. This rainfall may
produce life-threatening flash floods and mud slides.
