A flash flood watch is in effect for most of northern Arizona through 10 p.m. today. The National Weather Service issued the watch for areas including Flagstaff, Prescott, Williams, Show Low, Payson, Cottonwood and other areas. Forecasters say a surge of monsoon moisture will increase the chance of flash flooding through tonight. There have already been reports of flooding near Payson and severe weather in the Prescott area over the weekend. Flash floods can happen at anytime, so be prepared and keep your eyes on the weather. Also, don’t cross flooded streams or washes.
