DISCUSSION AND OUTLOOK
At 300 AM MDT (0900 UTC), the center of Hurricane Genevieve was
located near latitude 22.5 North, longitude 110.4 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 have decreased to 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). A gust to 90 mph (145 km/h) was recently reported in
Cabo San Lucas Marina, Baja California Sur.
The estimated minimum central pressure is 976 mb (28.82 inches).

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.
