FLAGSTAFF, AZ. — At approximately noon on Tuesday, a severe Monsoon storm sent flood waters into some Flagstaff area neighborhoods.
The rainfall over the entirety of the Museum Fire burn scar resulted in flooding that closed roads and overtopped mitigation. Significant debris was seen in the storm water given that a large area of the burn scar had not previously experienced heavy rainfall.
Not only was significant rainfall experienced on the burn scar itself, but also in the Sunnyside neighborhood. In an hour, 1.22 inches fell at Linda Vista and 1.5 inches was recorded downstream in neighborhoods.
The rainfall recorded equates to a 200- to 500-year rainfall event.
