DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1200 AM MDT (0600 UTC), the eye of Hurricane Blanca was located
near latitude 19.4 North, longitude 110.6 West.  Blanca is moving
toward the north-northwest near 10 mph (17 km/h), and this motion
with a slight increase in forward speed is expected through late
Monday.  On the forecast track, the center of Blanca is expected to
approach the southwestern coast of the Baja California peninsula on
Sunday and move near or along the coast on Monday.

Maximum sustained winds have decreased to near 115 mph (185 km/h)
with higher gusts.  Blanca is a category 3 hurricane on the
Saffir-Simpson Hurricane Wind Scale.  Additional weakening is
forecast through late Monday, and Blanca should become a tropical
storm by Sunday night before it reaches the southwestern coast of
the 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 175
miles (280 km).  An automated station on Socorro Island recently
reported sustained winds of 74 mph (118 km/h) and a wind gust of
101 mph (162 km/h).

The estimated minimum central pressure is 956 mb (28.23 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 on Sunday.  Tropical storm conditions are possible within
the tropical storm watch area starting Sunday night.

RAINFALL:  Blanca is expected to produce total rain accumulations of
6 to 10 inches over much of Baja California Sur and the southern
portion of the state of Baja California, with possible isolated
maximum amounts of 15 inches over Baja California Sur.  These rains
could produce life-threatening flash floods and mudslides.

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.  For additional information, please consult products
from your local weather office.
