Coordinates
40.449, -113.131 (the zone’s center; the record gives no point)

Heavy rains on the north end of the Oquirrh Mountains brought a river of mud, ash, and water into some yards in Lake Point. The rains fell over an area which had lost the erosion-controlling vegetation from a fire back in July. Up to six inches of mud and ash covered the yards.

What these are

Flash Flood
Flooding that begins within six hours of the rain that causes it, or of a dam or levee failure or ice jam release, often with deadly speed.

After NWS Directive 10-1605, the rules offices file Storm Data by.
