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 many of the lower elevations and wet, heavy snow in the mountains.
