BREAKING: 6 Die in Utah Flash Flooding

Six people died late Monday afternoon and at least another six people were reported missing after flash flooding occurred along the Utah-Arizona border, Utah media report.

The deadly flooding swept two vehicles off the road after floodwaters poured down a mountain, according to KUTV in Salt Lake City. As many as 16 people were in the two vehicles.

The rain came from the surrounding area outside of Hildale, a fire official told the TV station.

Rainfall amounts between 0.10 and 0.30 inches fell in the area late Monday afternoon and early evening, AccuWeather Meteorologist Brett Rathbun said. The Colorado City Municipal Airport on the Arizona side of the border picked up 0.25 inches between 4 and 5 p.m. MDT.

A flash-flood warning was in effect for the area until 8:15 p.m. MDT, the National Weather Service in Salt Lake City said. Rocks and other debris were deposited on local roadways.

The Virgin River in the Zion National Park rose 1.16 million gallons per minute in 1 hour or 2.5 feet, the weather service said.

"Showers and thunderstorms will be around the region for the next couple days," Rathbun said.

Flash flooding also was reported northeast of Colorado City with vehicles washed into a stream, fire officials said.
