Flash Flood — Aug 11, 2022

From August 11-14, thunderstorms produced gusty winds and localized flooding.

Flood — Feb 9, 2014

A series of moist weather disturbances moved across Utah during the second week of February, bringing an extended period of snowfall to northern Utah. In addition to the new snow, two avalanche fatalities occurred during this period of time.

Flood — Jun 24, 2011

Unseasonably warm temperatures were observed again at the end of June, leading to even more river flooding across Utah. Waterways that flooded significantly during this time period included Little Cottonwood Creek, the Duchesne River, and Spring Creek in Providence, Utah.

Flood — Apr 19, 2011

The combination of warmer temperatures and heavy rainfall caused flooding across many creeks and rivers across northern Utah. A few of the most impacted waterways included the Blacksmith Fork River, the Weber River, and Chalk Creek.

Flood — Jul 1, 2011

A few rivers across Utah continued to flood into the month of July, before finally receding in mid-July. The major rivers that continued to flood included the Logan River and the Duchesne River. Note that this episode began in June.
