The National Weather Service in Salt Lake City issued a flash flood warning for central Kane County in southern Utah on July 29.
The warning, which was effective from 8:07 PM MDT until 2:00 AM MDT on July 30, addressed life-threatening flash flooding hazards.
According to trained weather spotters, flash flooding was reported in Lick Wash downstream through Buckskin Gulch at 8:07 PM MDT.
Reports indicated that between 1 and 1.5 inches of rain had fallen upstream. This rainfall resulted in a very large flood wave overflowing its banks while moving south past the intersection with US-89 toward Buckskin Gulch.
Officials expected the flood wave to take approximately five hours to reach the confluence with the Paria River on the Utah side, just north of the Arizona border.
The warning noted that the flash flooding posed a threat to life and could impact creeks, streams, slot canyons, and normally dry washes.
Specific locations identified for potential flash flooding included Lick Wash Slot Canyon down to Buckskin Gulch in central Kane County.
