DISCUSSION AND OUTLOOK
At 600 AM MDT (1200 UTC), the center of Hurricane Genevieve was
located near latitude 23.0 North, longitude 111.0 West. Genevieve is
moving toward the northwest near 8 mph (13 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 80 mph (130 km/h) with higher
gusts. Further gradual weakening is expected today and through the
weekend. However, Genevieve is forecast to remain a hurricane
through 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 140
miles (220 km). An automated observing site near the Cabo San Lucas
Marina recently reported a wind gust to 72 mph (116 km/h).
The estimated minimum central pressure is 976 mb (28.82 inches).
HAZARDS AFFECTING LAND
WIND: Hurricane conditions will continue for the next few hours 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.
