DISCUSSION AND OUTLOOK
----------------------
At 300 PM MDT (2100 UTC), the center of Hurricane John was located
near latitude 22.0 North, longitude 113.5 West.  John is moving
toward the northwest near 15 mph (24 km/h), and this general motion
is expected to continue through Thursday.  A turn toward the
west-northwest is expected by Friday.  On the forecast track, the
center of John will pass well to the southwest of Baja California
Sur today through Thursday.

Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts.  Weakening is forecast during the next few days, and John is
expected to become a tropical storm on Thursday, and degenerate into
a remnant low Friday night or Saturday.

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).

The estimated minimum central pressure is 979 mb (28.91 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  John is expected to produce total rain accumulations of
1 to 2 inches over far southern Baja California Sur, with isolated
maximum amounts of 3 inches through Thursday.

SURF:  Swells generated by John are affecting portions of the
coasts of southwestern Mexico and the southern portion of the Baja
California peninsula and will spread northward along the west coast
of the Baja California peninsula during the next couple of days.
The swells are forecast to reach the coast of southern California
by late Thursday.  These swells are likely to cause life-threatening
surf and rip current conditions.  Please consult products from your
local weather office.
