WATCHES AND WARNINGS
--------------------
CHANGES WITH THIS ADVISORY:
 
The Hurricane Warning for the Southern Baja California peninsula 
from Los Barriles to Todos Santos has been replaced with a Tropical 
Storm Warning.
 
SUMMARY OF WATCHES AND WARNINGS IN EFFECT:
 
A Tropical Storm Warning is in effect for...
* Baja California peninsula from Los Barriles to Cabo San Lazaro
 
A Tropical Storm Watch is in effect for...
* The east coast of the Baja California peninsula from Los Barriles
to La Paz
 
A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area, in this case within the
next 24 hours. Tropical storm conditions have already been occurring
along the southern tip of the Baja California peninsula since last
night, and these conditions continue to spread northward over the
Southern Baja California peninsula, especially over higher terrain.
 
A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area.
 
For storm information specific to your area, please monitor
products issued by your national meteorological service.
 
 
DISCUSSION AND OUTLOOK
----------------------
At 900 AM MDT (1500 UTC), the center of Hurricane Genevieve was
located near latitude 23.3 North, longitude 111.4 West. Genevieve is
moving toward the northwest near 12 mph (19 km/h) and this motion is
expected to continue 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 75 mph (120 km/h) with higher
gusts.  Further gradual weakening is expected today and through the
weekend.  However, Genevieve is expected to remain a hurricane
through much of today 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 115 miles
(185 km). An automated observing site near the Cabo San Lucas
Marina recently reported a wind gust to 46 mph (74 km/h).
 
The estimated minimum central pressure is 984 mb (29.06 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND:  Tropical storm conditions will spread northward within the 
warning area in the southern Baja California peninsula through today 
and may linger into tonight.  Tropical storm conditions are possible 
within the watch area through the early afternoon, especially over 
higher terrain.
 
RAINFALL:  Genevieve is expected to produce additional rainfall
amounts of 2 to 4 inches across southern Baja California Sur, with
isolated storm totals of 12 inches across 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.
