 DISCUSSION AND OUTLOOK ---------------------- At 800 PM PDT (0300 UTC), the eye of Hurricane Rosa was located near latitude 22.4 North, longitude 118.9 West.  Rosa is moving toward the north near 12 mph (19 km/h), and this motion is expected to continue through Sunday morning.  A north-northeastward motion is expected to begin on Sunday and continue through Tuesday.  On the forecast track, the center of Rosa will approach the central and northern Baja California peninsula on Monday.  Rosa's remnants will then move quickly across the Desert Southwest on Tuesday.
Maximum sustained winds have decreased to near 100 mph (155 km/h) with higher gusts.  Additional weakening is forecast during the next couple of days, and Rosa is expected to become a tropical storm late Sunday.
Hurricane-force winds extend outward up to 30 miles (45 km) from the center, and tropical-storm-force winds extend outward up to 150 miles (240 km).
The estimated minimum central pressure is 969 mb (28.62 inches).
 HAZARDS AFFECTING LAND ---------------------- RAINFALL:  Between late Sunday and the middle of next week, Rosa is expected to produce the following total rainfall accumulations:
Baja California and northwestern Sonora: 3 to 6 inches, isolated 10 inches.
The Mogollon Rim of Arizona: 2 to 4 inches, isolated 6 inches.
Rest of the Desert Southwest, Central Rockies, and Great Basin: 1 to 2 inches, isolated 4 inches.
These rainfall amounts would produce life-threatening flash flooding and dangerous debris flows in the deserts, as well as landslides in mountainous terrain.
WIND:  Tropical storm conditions are expected to first reach the coast within the warning area by Monday morning.  Tropical storm conditions are possible within the watch area by late Monday.
SURF:  Swells generated by Rosa will affect portions of the coasts of southwestern Mexico, most of the west coast of the Baja California peninsula, and southern California during this weekend and early next week.  These swells are likely to cause life- threatening surf and rip current conditions.  Please consult products from your local weather office.
 NEXT ADVISORY ------------- Next intermediate advisory at 1100 PM PDT. Next complete advisory at 200 AM PDT.
