Saffir-Simpson Hurricane Wind Scale.  Additional weakening is
anticipated today.  Some fluctuations in intensity are possible on
Saturday, but a steady weakening trend is anticipated to begin by
Saturday night.

Hurricane-force winds extend outward up to 40 miles (65 km) from the
center and tropical-storm-force winds extend outward up to 115 miles
(185 km).

The estimated minimum central pressure is 942 mb (27.82 inches).


HAZARDS AFFECTING LAND
----------------------
SURF:  Swells generated by Rosa will affect portions of the coasts
of southwestern Mexico, the southern Baja California Peninsula, and
southern California late this week and over the weekend.  These
swells are likely to cause life-threatening surf and rip current
conditions.  Please consult products from your local weather office.
