Flash flood conditions on Sunday caused multiple vehicles to be stuck in water, traffic lights to stop working and underpasses to become treacherous throughout Flagstaff.
The intersection at Butler Avenue and Fourth Street was closed at one point due to the influx of water, and the underpass near Milton and Route 66 was facing long delays.
The Arizona Department of Transportation cautioned drivers to slow down on the I-17 south of Flagstaff in lower areas of the roadway due to the rainfall. State Route 89A also faced delays due to the weather.
Both ADOT and the National Weather Service recommend moving to higher ground and avoiding any flooded roadways at this time, and staying off the roads if you can.
The National Weather Service at Bellemont has a Flash Flood Watch in effect for Flagstaff and the surrounding areas until at least 8 p.m. The forecast calls for an 80 percent chance of precipitation this afternoon, and a 40 percent chance of more showers this evening. From there, the possibility of storms continues throughout the upcoming week.
