Maximum sustained winds are near 145 mph (230 km/h) with higher

Hurricane Wind Scale.  Little significant change in strength is
forecast today, with gradual weakening anticipated by Saturday, and
further weakening at a faster rate expected early next week.

Hurricane-force winds extend outward up to 40 miles (65 km) from the

(185 km).

The estimated minimum central pressure is 940 mb (27.76 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.
