DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1200 AM MDT (0600 UTC), the center of Hurricane Newton was
located near latitude 28.0 North, longitude 111.9 West.  Newton is
moving toward the north near 17 mph (28 km/h), and a turn toward the
north-northeast is expected later today.  On the forecast track, the
center of Newton will make landfall along the coast of northwestern
Mexico in the hurricane warning area this morning.  After landfall,
the center of Newton will move inland over northwestern Mexico and
move into southeastern Arizona by this afternoon.

Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts.  Little change in strength is expected before landfall in
northwestern Mexico, with rapid weakening expected afterward.
Newton is forecast to weaken to a tropical storm shortly after
landfall, and dissipate by early Thursday.

Hurricane-force winds extend outward up to 35 miles (55 km) from
the center and tropical-storm-force winds extend outward up to 230
miles (370 km).


HAZARDS AFFECTING LAND
----------------------
WIND:  For the Mexican mainland, hurricane conditions are expected
within the hurricane warning during the next few hours, and
preparations to protect life and property should be complete.
Tropical storm conditions will continue spreading northward tonight
within the warning area in northwestern Mexico.

For the Baja California peninsula, tropical storm conditions will
gradually subside during the next few hours.

Tropical storm conditions could spread into portions of southeastern
Arizona by this afternoon.

RAINFALL:  Newton is expected to produce total rain accumulations of
8 to 12 inches over the Mexican state of Baja California Sur, and 4
to 8 inches over northern Sinaloa and Sonora states through
today.  Isolated maximum amounts of 18 inches are possible in
Baja California Sur.  Moisture associated with Newton is expected to
produce total rain accumulations of 1 to 3 inches with locally
higher amounts over southeastern Arizona and southern New Mexico
through Thursday.  In all of these locations, heavy rain could cause
life-threatening flash floods and mud slides, especially in
mountainous terrain.

STORM SURGE:  A dangerous storm surge is expected to produce
significant coastal flooding near and to the east of the track of
the center within the hurricane warning area.  Near the coast, the
surge will be accompanied by large and destructive waves.
Elsewhere, elevated water levels are expected in areas of onshore
wind.

SURF:  Large swells generated by Newton are expected to affect the
coast of southwestern Mexico through this morning, but will begin to
subside later today.  Large swells are occurring along the coast of
Baja California Sur and should spread northward through the Gulf of
California today.  These swells are likely to cause life-threatening
surf and rip current conditions.  Please consult products from your
local weather office.
