Monsoon rains flood parts of Flagstaff, high heat to return to Phoenix area
PHOENIX — Rain from monsoon storms overwhelmed parts of Flagstaff on Sunday and there was a possibility of more flooding on Monday.
Between 1½ and 2½ inches of rain fell in about an hour, the Weather Channel reported, trapping vehicles on roads and blowing out power to traffic lights.
A flash flood warning went into effect that lasted through the evening. The downpour swelled the banks of the Agua Fria River and prompted a flash flood warning in Black Canyon City, less than 13 miles from the Maricopa County line.
The Red Cross opened a shelter at Sinagua Middle School and drivers on State Route 89A also faced weather-related delays.

There was a chance more flooding would hit the area.
Monsoon moisture is keeping storm chances around through at least the first half of the week.
Storms could produce heavy rain and flash flooding today, especially in rain-soaked areas along the Rim.
