Arizona Gov. Jan Brewer declared a state of emergency Monday
after unusually heavy rainfall flooded several major roads,
triggered power outages and school closings in Phoenix, and caused
one death.
A woman in her 50s was killed Monday morning when her car was
swept away by rushing water in Tucson. Authorities hadn't
identified her.
Phoenix Mayor Greg Stanton also declared a local state of
emergency after the city saw record daily rainfall of more than 3
inches at Phoenix Sky Harbor International Airport. In an average
monsoon season, which typically runs from July to September, the
Phoenix area receives about 2.71 inches of rain. Maricopa and La
Paz counties also declared states of emergency.
"I grew up here in Phoenix and I've never seen anything like
it," Mr. Stanton said.
Rainfall in Tucson also broke records, reaching 1.87 inches by
midday.
Ms. Brewer said the rains had damaged residential property and
prompted evacuations, and she warned flooding could continue over
the coming days. She called for $200,000 from the state's general
fund to be made available to the Arizona Department of Emergency
Management and authorized mobilization of the Arizona National
Guard.
Flooding is common in Arizona. Several people drown in
floodwaters annually in the mountainous desert state, according to
the U.S. Geological Survey. But Arizona, which has more than 6.5
million residents, accounted for less than 50,000 flood-insurance
policies in 2013, according to the National Flood Insurance
Program.
The National Weather Service issued flash-flood warnings Monday
for counties throughout Arizona, as well as parts of southern
Nevada and California. Authorities encouraged Arizona residents to
avoid several roadways and stay home Monday.
In Phoenix, as many as 10,000 homes were without power early
Monday morning, but that fell to 250 by late morning, according to
Arizona Public Service Co., the local power company.
Interstate 10 was flooded and inaccessible just west of downtown
Phoenix on Monday morning, and emergency workers rescued several
stranded drivers from the major freeway. Bart Graves, a spokesman
for the Arizona Department of Public Safety, said at least a dozen
cars were completely submerged.
The state Department of Transportation said pumps were working
to clear water from the freeways, and progress would speed up as
soon as the rain cleared.
Mr. Stanton said crews were working quickly to assess the damage
around Phoenix, with a particular focus on the water delivery and
drainage systems. "We're concerned about overflowing those
systems," Mr. Stanton said. "They are full right now so we're
monitoring them very closely."
Heavy rains also hit parts of Southern California overnight,
closing several roads in parts of Riverside and San Bernardino
counties, but no major damage was reported.
