What the National Weather Service wrote

A USGS stream gage on the Moenkopi Wash (MOEA3) measured an 8 foot rise in 3 hours, from 18.69 to 26.74 ft. This would put the Moenkopi Wash into moderate flood stage. The flow increased from 13 to 2860 cfs in that time period. The Moenkopi Wash would further rise into major flood stage, cresting at a stage of 28.81 ft and 4867 cfs between 6:45 pm and 7:30 pm before beginning to recede.

The wider storm

Remnant moisture from two tropical cyclones, Priscilla and Raymond moved into the state of Arizona. Two west coast troughs interacted with this remnant moisture and provided ample lift and shear for heavy rain and severe thunderstorms. The rain led to creek and stream level rises and some flash flooding.

Began near Moenkopi (36.1000, -111.2000).
