DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 300 AM MDT (0900 UTC), the eye of Hurricane Blanca was located
near latitude 16.9 North, longitude 108.9 West. Blanca is moving
toward the northwest near 12 mph (19 km/h) and this motion is
expected to continue today.  A turn toward the north-northwest is
forecast by tonight.  On the forecast track, the center of Blanca is
expected to approach the coast in the warning area late Sunday.

Satellite imagery indicates that maximum sustained winds have
increased to near 120 mph (195 km/h) with higher gusts.  Blanca is a
category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale.
Little change in strength is forecast today.  Weakening is forecast
tonight and Sunday, but Blanca is forecast to be near hurricane
strength as it approaches the southern Baja California peninsula.

Hurricane force winds extend outward up to 60 miles (95 km) from the
center and tropical storm force winds extend outward up to 205 miles
(335 km).

The estimated minimum central pressure is 952 mb (28.12 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Tropical storm conditions are expected to first reach the
warning area on Sunday, making outside preparations difficult or
dangerous.  Hurricane conditions are possible in the hurricane
watch area Sunday and Sunday night.

RAINFALL:  Blanca is expected to produce total rain accumulations of
3 to 5 inches over much of Baja California Sur and the southern
portion of Baja California, with possible isolated maximum amounts
of 7 inches over Baja California Sur.

SURF:  Swells generated by Blanca are affecting the coast of
southwestern Mexico, the Pacific coast of the Baja California
peninsula, and the southern Gulf of California.  These swells are
likely to cause life-threatening surf and rip current conditions.
