moving toward the northwest near 17 mph (28 km/h), and this

speed through early Thursday.  On the forecast track, the center of
Genevieve is expected to move parallel to but well offshore the
coast of southwestern Mexico during the next day or so. The center
of the hurricane is forecast to move to the southwest of the
southern portion of the Baja California peninsula on Wednesday
night and Thursday.
 
Maximum sustained winds have increased to near 115 mph (185 km/h) 
with higher gusts.  Genevieve is a category 3 hurricane on the 
Saffir-Simpson Hurricane Wind Scale.  Additional rapid 
strengthening is forecast during the next 12 to 24 hours.
 
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 962 mb (28.41 inches).

area in the southern Baja California peninsula by Wednesday 
afternoon, especially over higher terrain.  Tropical storm 
conditions are possible within the watch area by Wednesday night or

SURF:  Large swells produced by Genevieve are affecting portions of
the southern coast of Mexico and will spread northward along the
southwestern and west-central coast of Mexico to the Baja California
peninsula through Wednesday.  These swells are likely to cause
life-threatening surf and rip current conditions.  Please consult
