A series of cold and moist storms moved through Utah in the last week of October. These storms dropped the first significant snowfall of the season on the higher terrain across the state, and also caused strong gusty winds in valleys across northern Utah.
Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS SLC wrote it up.
