Dense violent storm on Sunday created flash flooding conditions in northern parts of Arizona.

According to National Weather Service, due to relentless, heavy downfall in Flagstaff, flash flooding conditions were in effect in various areas.

Encompassing areas, such as Prescott, Payson, Tonto Basin and more, were likewise under a flash flood watch.

The American Red Cross concisely opened a shelter in Flagstaff at Sinagua Middle School, 3950 E. Butler Ave., in order to aid residents affected by flooding.

Early Sunday, a few sprinkles were spotted in the Valley but residents did not see much more. There was a flimsy chance for showers and thunderstorms in the metro Phoenix area, according to the National Weather Service.

In the Valley, skies are set to remain cloudy with a 30 percent chance of rain and an expected high of 99 degrees, according to the week's forecast. Sunday night's low was expected to hit 83 degrees with a 20 percent chance of rain.

For those encountering flash floods, officials advise motorists to avoid driving through flooded roads and rushing waters.

As little as a foot of water can float many vehicles, and two feet of rushing water can carry most vehicles away, including SUVs and pickup trucks, according to the Federal Emergency Management Agency.
