Four riders were boot packing up the east ridge of the Pfeifferhorn when a shallow 2-6 inch deep wind slab failed. All four people were caught and carried, and some suffered injuries. Link to the report can be found

This morning it's trying to snow lightly in the mountains as a closed low (storm) currently sits over Las Vegas. As this closed low spins counter-clockwise (cyclonic) and moves eastward, we hopefully will see some spillover moisture on an easterly flow. Typically this is not a good pattern for accumulating snow for Northern Utah or the Provo Range. Fingers crossed that we can stack some flakes. As this storm moves eastward into Arizona, we could see an increase in the east winds today, with speeds hitting 10-20 mph at the uppermost ridgelines.
Current mountain temperatures are in the upper 20's to low 30's °F. Winds are from the northeast and blowing 5-10 mph. Hopefully, the winds will remain calm, but with east winds, you never know. The snow surface has taken a beating over the past few days from warm temperatures, sun, and wind. Only mid to upper elevation wind and sun-protected slopes held dry settled powder snow.
We had one report of a wind slab avalanche from the Wasatch Powder Birds off of Mill Canyon Peak. This avalanche was on an upper elevation southeast facing aspect and broke 8 inches deep and 100 feet wide. Nobody was caught. You can find all the recent avalanche activity
