up to an inch of rain is expected across the Baja California 
peninsula.  For the southwestern United States, 2 to 4 inches of 
rain, with local storm total maxima to 6 inches, are expected across
portions of central and northern Arizona, southern Utah, and 
southwest Colorado through Saturday.  Flash flooding is likely in  
portions of central Arizona, with scattered areas of flash flooding 
expected across the remainder of Arizona, southern Utah, southwest 
Colorado, and far northwest New Mexico.

SURF: Large swells generated by Priscilla are affecting the Pacific
coast of Baja California Sur as well as portions of coastal
southwestern and west-central Mexico.  These swells are likely to
cause life-threatening surf and rip current conditions, in addition
to some coastal flooding. Please consult products from your local
weather office.
