Highlights
Overall, the avalanche danger is generally LOW, and normal caution exists. Isolated shallow, soft, or hard slabs of wind-drifted snow may exist in exposed terrain at the upper elevations. Soft slabs may exhibit shooting cracks and are typically sensitive to triggers. Meanwhile, hard slabs can be smooth and round, releasing once well onto the slope.
In wind-protected terrain, the possibility of triggering loose sluffs that can catch and carry a skier or rider down the slope remains.
Recent Activity
Yesterday, two reports of shallow hard slab avalanches of wind-drifted snow released 6-12” deep on a layer of facets in the Provo area.
- Miller Hill - Outside of the Snowbird Boundary - American Fork - 10,000’ - East Aspect - 12” deep - 50’ wide - ran 150’ (See video below)
- East Provo Peak - South of Cascade Peak - 10,900’ - East Aspect - 6” deep - 30’ wide

Snow and Weather
This morning, under cloudy skies, there is an inversion in the mountains. Temperatures are in the low 30s F along ridgelines and in the upper teens at trailheads. Winds are primarily from the northwest, gusting in the 20s mph along mid-elevation ridges with gusts in the 30s along the highest peaks.
Today, skies remain partly cloudy, temperatures will rise into the upper 20s F, and the northwesterly winds will remain generally light, gusting up to 25 mph along the highest peaks.
General Outlook: The weather models show weak disturbances ahead that lack precise aim or direction. We’ll keep an eye on it. In the meantime, travel is easy, and skiing and riding conditions are pretty good in sun and wind-sheltered terrain without old tracks. As the surface continues to weaken, the riding will continue to improve a bit in protected areas. Read, loud pow. While this could be an issue once we add load to the weak surface, we can enjoy some soft turns now.
Additional Info
What happened to the Persistent Weak Layer (PWL) problem? The PWL problem first appeared in the December 1 forecast and was removed from the forecast on Wednesday, December 20. On Thursday, December 21, forecasters Nikki Champion and Greg Gagne talked about the PWL problem over a Zoom call and their 5-minute discussion. Be sure to watch the video.
