Abstract
Record-breaking amounts of precipitation occurred in northern Utah during the period January 29 to February 2, 1963. The synoptic situation associated with this storm is discussed and some of the possible factors involved in the production of heavy precipitation in this area are listed. A brief comparison between the hydrologically critical features of this storm and those of the heavy rain-on-snow storm which occurred in February 1962 is made, and the importance of soil condition in flood production is emphasized.
