DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 600 AM MDT (1200 UTC), the center of Hurricane Norma was located
near latitude 19.1 North, longitude 110.1 West. Norma has been
nearly stationary, but a slow northward motion should begin later
today and continue through Sunday.

Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts.  Some slight strengthening is possible during the next day or
two.

Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 90
miles (150 km).

The estimated minimum central pressure is 987 mb (29.15 inches).


HAZARDS AFFECTING LAND
----------------------
SURF:  Swells generated by Norma will begin affecting portions
of the coast of southwestern Mexico and Baja California Sur later
today and continue into early next week. These swells are likely
to cause life-threatening surf and rip current conditions.  Please
consult products from your local weather office.

WIND:  Tropical storm conditions are expected to first reach the
coast within the warning area by early Sunday, making outside
preparations difficult or dangerous. Tropical storm conditions are
possible within the watch area by late Sunday or early Monday.

RAINFALL:  Norma is expected to produce total rainfall accumulations
of 8 to 12 inches over the southern portion of the Mexican state of
Baja California Sur, with isolated maximum amounts in excess of 20
inches possible. These rainfall amounts may produce life threatening
flash floods.
