DISCUSSION AND OUTLOOK
----------------------
At 900 AM MDT (1500 UTC), the center of Hurricane John was located
near latitude 17.9 North, longitude 109.8 West. John is moving
toward the northwest near 9 mph (15 km/h), and a faster
northwestward motion is forecast for the next few days.  On the
forecast track, John should pass to the southwest of Baja
California Sur Wednesday and Thursday.

Maximum sustained winds have increased to near 105 mph (165 km/h)
with higher gusts.  Some additional strengthening is forecast during
the next 24 hours, and John is forecast to become a major hurricane
tonight or early Wednesday.  Steady weakening is expected to begin
Wednesday night and continue into early Friday.

Hurricane-force winds extend outward up to 35 miles (55 km) from the
center and tropical-storm-force winds extend outward up to 125 miles
(205 km).

The estimated minimum central pressure is 969 mb (28.62 inches).


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

SURF:  Swells generated by John will affect the coasts of
southwestern Mexico and the southern portion of the Baja
California peninsula during the next day or so.  These swells are
likely to cause life-threatening surf and rip current conditions.
