Record-setting rains slammed the southwestern United States on Monday, turning roadways into rivers as flash floods washed away cars.
Up to 200 children were briefly trapped in an elementary school in Moapa, Nevada, due to the waters, the state highway patrol said Monday night.
The students at Perkins Elementary school, about 60 miles from Las Vegas, were with teachers and not in danger, said Highway Patrol Spokesman Loy Hixson.
Flash flooding also washed a portion of Interstate 15 away near the community of Glendale, taking many vehicles with it. No one has been injured but it has taken so much of the highway that it may not be fixed until Wednesday, Hixson said.
In Arizona, the governor declared an emergency Monday as flooding from the historic rains closed roads and schools in her state.
A woman was killed after her car was submerged in floodwaters, the Tucson Fire Department said. Rescuers were unable to reach the vehicle in time.
"Within a minute of us getting there, the car washed away," Capt. Barrett Baker told CNN. The waters were up to 12 feet deep, he said, and swept the car for several blocks.
In Phoenix, the flooding left morning commuters stranded on Interstate 10, CNN affiliate KTVK reported.
