What the National Weather Service wrote

Heavy rain led to a debris flow on Utah Highway 191 between mile markers 104 and 112.

The wider storm

Substantial monsoon moisture remained over the area as high pressure drifted east over the Plains. As a result, widespread showers and thunderstorms developed with many storms producing heavy rain. This led to several reports of flash flooding and debris flows across portions of southeast Utah including over the Pack Creek Fire burn scar.
