DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 800 AM MST (1500 UTC), the center of Hurricane Sandra was located
near latitude 19.6 North, longitude 108.4 West. Sandra is moving
toward the north-northeast near 12 mph (19 km/h), and this motion is
expected to continue for the next 24 to 36 hours. On the forecast
track, the center of Sandra will pass west of Las Islas Marias this
evening and make landfall within the warning area early Saturday.

Maximum sustained winds are near 100 mph (155 km/h) with higher
gusts. Rapid weakening is forecast during the next 48 hours, and
Sandra is forecast to weaken to a tropical storm by tonight and
become a remnant low and dissipate after moving inland over Mexico
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 (28.71 inches).

Mexican state of Baja California Sur. Rainfall totals of 4 to 6
inches with isolated maximum amounts of 10 inches are possible
across the Mexican states of Sinaloa, Nayarit, northwest Jalisco,
western Durango and southern Chihuahua. This rainfall may produce
