Flood — Jan 19, 2012
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. This rain, when combined with frozen ground and snowmelt, produced flooding in portions of Cache Valley and Ogden Valley.
Flood — Jun 25, 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.
