HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Norma is expected to produce total rainfall accumulations
of 1 to 2 inches over the southern portion of the Mexican state of
Baja California Sur, with isolated maximum amounts up to 4 inches.
These rainfall amounts may produce life-threatening flash floods.

WIND:  Tropical storm conditions are possible within the watch area
tonight or early Monday.

SURF:  Swells generated by Norma are affecting portions of the coast
of southwestern Mexico and Baja California Sur and will continue
into early next week.  These swells are likely to cause life-

products from your local weather office.
