DISCUSSION AND OUTLOOK
----------------------
At 300 PM MDT (2100 UTC), the center of Tropical Storm Genevieve was 
located near latitude 23.9 North, longitude 112.4 West. Genevieve is 
moving toward the northwest near 12 mph (19 km/h), and this general 
motion is expected to continue through Saturday night.  On the 
forecast track, the center of Genevieve is expected to pass just 
west of the southern portion of the Baja California peninsula 
through this evening, and move away from the peninsula on Friday.
 
Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts.  Gradual weakening is expected, and Genevieve is expected to 
become a remnant low this weekend.
 
Tropical-storm-force winds extend outward up to 105 miles (165 km) 
from the center. An automated observing site near Puerto Cortes 
recently reported a wind gust to 46 mph (74 km/h).
 
The estimated minimum central pressure based on data from an Air 
Force Reserve Hurricane Hunter aircraft is 985 mb (29.09 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND:  Tropical storm conditions are expected to continue within
the warning area in the southern Baja California peninsula through
this evening, especially over higher terrain.
 
RAINFALL:  Genevieve is expected to produce additional rainfall
amounts of 1 to 3 inches across southern Baja California Sur, with
isolated storm totals of 12 inches across far southern Baja
California Sur.  While rainfall will generally continue to decrease
in intensity, some instances of flash flooding and mudslides remain
possible through this evening.
 
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.
