What the National Weather Service wrote

The Colorado Department of Transportation reported Colorado Highway 141 had alternating traffic due to mudslide clean-up between County Road Y11 and County Road Q12.

The wider storm

An area of low pressure originating from the Pacific Northwest dropped into the Great Basin. As this feature slowly lifted across the region it tapped into a stream of monsoon moisture from the south. The upper level lift paired with the abundance of moisture resulted in widespread showers and thunderstorms. Some storms produced heavy rain which led to localized debris flows across portions of western Colorado.

Began near Uravan (38.3900, -108.7500).
