A flash flood in Arizona killed eight people, including two children, and two others remain missing Sunday, authorities said.
More than 100 people were thought to have been at the Cold Springs Swimming Hole in Tonto National Forest when the flood struck on Saturday afternoon.
At least four people were rescued from the water by helicopter crews.
According to the report, the list of casualties includes the 60-year-old Celia Garcia and her kids Maria Raya and her 27-year-old husband Miguel Garnica, their children Emily and Mia, 24-year-old Maribel Raya-Leon and her children Jonathan and Erika, and 14-year-old Javier Raya.
Four people were rescued Saturday and airlifted to Banner Hospital, he said.
The National Weather Service in Phoenix said that most of Arizona was under flash flood watch until Monday evening, warning that "heavy rains can produce flash flooding of low lying, normally dry areas such as washes".
Soon, there were videos posted in social media which captured the deadly flash floods in the area. Had they been swept downstream, they would have been sent over a 20-foot waterfall, Alexander said. There were no notices or warnings at the trailhead, Alexander said.
Almost an inch of rain is believed to have fallen between 1:15 p.m. and 3:55 p.m. local time on Saturday, according to the Automated Weather Observation Station in Payson, just south of the swimming hole.
"It's monsoon season in Arizona and these storms build quickly and dump a lot of moisture", Hornung explained. It happens every year.
"It was just a panic moment after we see the water coming down", she said.
Elsewhere in the U.S., officials are concerned flooding could impact the start of classes next month. Visitors are reminded to be vigilant about the weather, he said. When Nancy tried to find a way out, it got worse. The group was trapped by floodwaters in a popular slot canyon that was as narrow as a window in some spots and went several hundred feet deep.
