located along the coast near latitude 28.7 North, longitude 111.8
West. Newton is moving toward the north near 17 mph (28 km/h)
and a turn toward the northeast is expected over the next day or so.
On the forecast track, the center will move over extreme
northwestern Mexico this morning and into southeastern Arizona this
Maximum sustained winds are near 70 mph (110 km/h) with higher
gusts. Rapid weakening will occur today as the center moves
inland, and Newton should weaken to a tropical depression later
today and dissipate by early Thursday.
Tropical-storm-force winds extend outward up to 230 miles (370 km)
from the center. A Mexican Navy station at Guaymas reported a
sustained wind of 43 mph (69 km/h) with a gust to 66 mph (107 km/h).

HAZARDS AFFECTING LAND
WIND: Tropical storm conditions will continue over portions of the
warning area in mainland Mexico this morning, but winds should
subside by this afternoon.
Tropical storm conditions could spread into portions of southeastern
Arizona later today.
RAINFALL: Newton is expected to produce additional rain
accumulations of 1 to 3 inches over the central portion of the Baja
California peninsula. Newton is expected to produce total rain
accumulations of 3 to 6 inches, and possible isolated maximum
amounts of 10 inches, over the Mexican state of Sonora. 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.
This heavy rainfall may cause life-threatening flash floods and mud
slides in areas of mountainous terrain.
STORM SURGE: A dangerous storm surge is expected to produce
significant coastal flooding near and to the southeast of the track
of the center within the tropical storm 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. Water levels will diminish later today.
SURF: Swells associated with Newton over the Gulf of California
will begin to subside.
