Elevated Flash Flood Risk

A flash flood watch is in effect from 11 AM MST this morning to 8 PM MST this evening for northwestern Arizona. Thunderstorms are expected to develop this afternoon and continue into the early evening hours across northwestern Arizona. With deep monsoonal moisture in place, any stronger storm will have the potential to produce heavy rainfall and cause flash flooding.

There is an elevated risk for flash flooding across northwestern Arizona, with deep monsoon moisture in place and already saturated soils. Consider changing your plans if you were going to hike, boat, or paddleboard to a slot canyon or normally dry wash. Flash flooding will be possible in creeks, normally dry washes, swimming holes, and over recently burned areas.
