DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 300 AM MDT (0900 UTC), the center of Tropical Storm Blanca was
located near latitude 23.8 North, longitude 111.5 West.  Blanca is
moving toward the north-northwest near 15 mph (24 km/h), and this
general motion is expected to continue through Tuesday.  On the
forecast track the center of Blanca will move near or over portions
of the southern and central Baja California peninsula today through
Tuesday.

Maximum sustained winds have decreased to near 50 mph (85 km/h) with
higher gusts.  Additional weakening is forecast, and Blanca is
expected to weaken to a tropical depression by tonight.  Blanca will
likely dissipate near or over central or northern portions of the
Baja California peninsula on Tuesday.

Tropical storm force winds extend outward up to 150 miles (240 km)
from the center.  A wind gust to 40 mph (65 km/h) was recently
reported at La Paz, Mexico.

The estimated minimum central pressure is 994 mb (29.36 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Tropical storm conditions will continue spreading northward
in portions of the warning area today.  Tropical storm conditions
are possible within the watch area today.

RAINFALL:  Blanca is expected to produce total rain accumulations of
3 to 5 inches over much of Baja California Sur and the southern half
of the state of Baja California, with isolated maximum amounts of 10
inches over Baja California Sur.  These rains could produce life-
threatening flash floods and mud slides.  Rainfall associated with
Blanca and its remnants could begin to affect portions of the
southwestern United States on Tuesday.

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

weather office.
