Mountain conditions this morning feature temperatures in the single digits with some of the warmer spots in the low teens. Winds are out of the west/northwest and generally light, less than 10 mph, although some stations along upper elevation ridgelines have recorded overnight gusts in the upper teens. The Salt Lake and Park City mountains squeezed out another 3-7" of 5% Wasatch fluff overnight, bringing 24-hour snow totals of 6-12". As is often the case with a northwest flow, upper Little Cottonwood fared best.
Snowpack depths in the Cottonwoods and along the Park City ridgeline range from 2-4', with even higher localized amounts in the upper Cottonwoods.
Perfect December weather continues today with mostly-cloudy skies and continued snow showers with mountain temperatures in the teens. The cold northwest flow may deliver another 2-4" of low-density snow during the day today, especially in favored locations such as upper Little Cottonwood. Winds will be out of the west/northwest and generally light, with gusts in the teens along the upper elevation ridgelines. Chance for continued snow showers overnight.
Other than some minor sluffing in the loose storm snow, the only avalanche activity reported from Sunday was a remotely-triggered slide in Cardiff Fork
shown in the photo below. This was on a northwest-facing aspect at 10,000' and 50' wide, likely running on weak faceted snow down near the ground.
for an excellent field report from pro observer Andy Paradis and UAC executive director Chad Brackelsberg from the Park City mountains.
