DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 300 PM MDT (2100 UTC), the center of Hurricane Blanca was located
near latitude 15.3 North, longitude 107.5 West. Blanca is moving
toward the northwest near 9 mph (15 km/h). A gradual turn to the
north-northwest is expected on Saturday. On the forecast track, the
center of Blanca will approach the southern Baja California
peninsula on Sunday.

Data from an Air Force reconnaissance plane indicate that the
maximum sustained winds are near 90 mph (150 km/h) with higher
gusts. No significant change in strength is forecast during the
next 24 hours, but Blanca should begin to weaken on Sunday as it
approaches the Baja California peninsula.

Hurricane force winds extend outward up to 35 miles (55 km) from the
center, and tropical storm force winds extend outward up to 200
miles (325 km).

The minimum central pressure recently reported by the reconnaissance
plane was 976 mb (28.82 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Tropical storm conditions are possible within the watch
area by early Sunday.

SURF:  Swells generated by Blanca are affecting the coast of
southwestern Mexico and have reached 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.
