DISCUSSION AND OUTLOOK
----------------------
At 900 AM MDT (1500 UTC), the eye of Hurricane Aletta was located
near latitude 15.8 North, longitude 111.2 West.  Aletta is moving
toward the west-northwest near 6 mph (9 km/h), and a west-northwest
to northwest heading at about the same forward speed is expected
through Saturday.  On Sunday, the hurricane is forecast to begin a
gradual turn toward the west.

Maximum sustained winds have increased to near 140 mph (220 km/h)
with higher gusts.  Aletta is a category 4 hurricane on the
Saffir-Simpson Hurricane Wind Scale.  Fluctuations in intensity are
likely for the next 24 hours, and some additional strengthening is
possible during that time.  The hurricane is forecast to rapidly
weaken over the weekend and will likely become a tropical storm on
Sunday.

Hurricane-force winds extend outward up to 30 miles (45 km) from the
center and tropical-storm-force winds extend outward up to 105 miles
(165 km).

The estimated minimum central pressure is 943 mb (27.85 inches).


HAZARDS AFFECTING LAND
----------------------
SURF:  Swells generated by Aletta will begin to affect portions of
the coast of west-central mainland Mexico and the west coast of
Baja California Sur later today and will continue through the
weekend.  These swells are likely to cause life-threatening surf and
rip current conditions.  Please consult products from your local
weather office.
