DISCUSSION AND OUTLOOK
----------------------
At 1200 AM MDT (0600 UTC), the eye of Hurricane Genevieve was
located near latitude 22.3 North, longitude 110.2 West. Genevieve is
moving toward the north-northwest near 7 mph (11 km/h).  A turn
toward the northwest is expected later this morning, with that
motion continuing through Saturday.  On the forecast track, the
center of Genevieve is expected to pass just to the southwest and
west of the southern portion of the Baja California peninsula today,
and move away from the peninsula on Friday.
 
Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts. Gradual weakening is expected today and through the weekend.
However, Genevieve is forecast to remain a hurricane through this
morning while it passes just to the southwest and west of the
southern Baja California peninsula.
 
Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 140
miles (220 km).  A sustained wind of 65 mph (105 km/h) and a gust to
84 mph (135 km/h) was recently reported in Cabo San Lucas Marina,
Baja California Sur.
 
The estimated minimum central pressure is 979 mb (28.91 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND:  Hurricane conditions are occurring in the warning area.
Tropical storm conditions will spread northward within the warning
area in the southern Baja California peninsula through today.
Tropical storm conditions are possible within the watch area later
this morning, especially over higher terrain.
 
RAINFALL:  Genevieve is expected to produce rainfall amounts of
4 to 8 inches with isolated totals of 12 inches across portions
of far southern Baja California Sur. This rainfall may lead to
life-threatening flash flooding and mudslides.
 
SURF:  Large swells produced by Genevieve are affecting portions of
the west-central coast of Mexico and are spreading northward along
the coast of the Baja California peninsula.  These swells are
likely to cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.
