DISCUSSION AND 48-HOUR OUTLOOK
At 600 PM MDT (0000 UTC), the center of Hurricane Newton was located
near latitude 26.3 North, longitude 111.7 West. Newton is moving
toward the north-northwest near 18 mph (30 km/h). A turn toward the
north is expected tonight, and this motion is expected to continue
through Wednesday. On the forecast track, the center of Newton will
emerge over the Gulf of California within the next few hours. The
center of Newton should reach the coast of northwestern Mexico in
the hurricane warning area early Wednesday, move inland over
northwestern Mexico, and then move into southeastern Arizona by
Maximum sustained winds are near 75 mph (120 km/h) with higher
gusts. Little change in strength is expected before landfall in
northwestern Mexico, followed by rapid weakening thereafter.
Newton is expected to weaken to a tropical storm on Wednesday and
dissipate by 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). An automated station in Loreto, Mexico, recently
reported a sustained wind of 48 mph (77 km/h) and a wind gust of 89
mph (144 km/h). A wind gust of 40 mph (65 km/h) was recently
reported at the Los Mochis airport in the state of Sinaloa.
The estimated minimum central pressure is 986 mb (29.12 inches).
HAZARDS AFFECTING LAND
WIND: For the Baja California peninsula, tropical storm and
hurricane conditions continue to occur over much of the warned area
of the southern portion of the Baja California peninsula. These
hazardous wind conditions will spread northward during the remainder
of today within the warning areas.
For the Mexican mainland, hurricane conditions are expected within
the hurricane warning area by early Wednesday morning, and
preparations to protect life and property should have been
completed. Tropical storm conditions are beginning over
northwestern Mexico within the warning area, and these conditions
will gradually spread northward tonight.
Tropical storm conditions could spread into portions of southeastern
Arizona by Wednesday afternoon.
RAINFALL: Newton is expected to produce total rain accumulations of
8 to 12 inches over the Mexican state of Baja California Sur, and 5
to 10 inches over the Mexican states of Sinaloa, Sonora, western
Nayarit, and Jalisco through Wednesday. 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 to
southwestern and south-central 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 tonight, but will begin to
subside on Wednesday. Large swells are occurring along the coast of
Baja California Sur and should spread northward through the Gulf of
California tonight and Wednesday. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.
