154 first-hand accounts of flood events in Utah, ranked by impact. Each is a NOAA-written narrative of the moment.
Deep moisture moved into southern Utah during the first week of June, with thunderstorms producing several flash floods across the area. While the threat of large hail primarily remained across northern Utah in early June, a couple of storms did manage to produce large hail in…

Read the full account →Snowmelt water overflowed a high elevation irrigation canal which was blocked with ice. The overflow caused rapid erosion of loose soils on a forested mountainside 24 miles northwest of Vernal. This resulted in a 1000 yard long chasm up to 300 feet deep and 1000 feet wide.

Read the full account →Deep Pacific moisture, combined with embedded weather disturbances moving through the region in the middle of January, resulted in heavy and wet snowfall in the mountains and mountain valleys of northern Utah. Occasional heavy rain was observed in the northern Utah valleys.
Read the full account →A potent Pacific storm system moved through Utah on January 21st and 22nd. Gusty winds were observed both ahead of and behind the strong cold front. Flooding, again due to heavy rain on top of frozen ground, was observed in the Wasatch mountain valleys.

Read the full account →An upper-level shortwave trough combined with deep monsoon moisture to produce a line of strong thunderstorms that moved into the northwest corner of Utah county and over the Cedar Fort area.
Read the full account →A large and very moist Pacific storm system brought widespread heavy precipitation to Utah over a five day period. The storm pulled a continuous stream of tropical moisture ahead of it and, combined with numerous embedded shortwaves, resulted in almost non-stop rainfall across…
Read the full account →A fairly mild storm system brought another round of significant precipitation to southwestern Utah. The storm produced enough rainfall to generate a flash flood in Brookside along the Santa Clara River in Washington County.
Read the full account →Heavy rain resulted in flash flooding along Mill Creek in Moab. During the flash flood, the swollen creek was running 15 feet deep and 45 feet wide.

Read the full account →Warm spring temperatures resulted in rapid melting of the snowpack which caused flooding of the Whiterocks River and the Uinta River near the town of Whiterocks. After years of drought and a lack of flushing flows, debris buildup in rivers and creeks enhanced flooding.
