    There is no mystery to what is going on right now. All the weak snow that formed in December and January has proven to be deadly. We've seen natural and human-triggered avalanches. Persistent Weak Layers of facets do not stabilize rapidly. This means that the snowpack will remain unstable for a long time to come. Dangerous avalanche conditions will continue through the weekend.

Recent Activity

The UAC is deeply saddened to report two avalanche fatalities. The first occurred on Wednesday, February 18th in the Big Flat area of Snake Creek near Midway. A snowmobiler was caught, carried, and buried in an avalanche, and unfortunately, recovery efforts were unsuccessful. The preliminary report can be found HERE.

The second fatality occurred on Thursday, February 19th, in the backcountry adjacent to Brighton Ski Resort. A girl skiing was caught, carried, and buried by an avalanche and did not survive. Our sincerest condolences are with all those impacted. The UAC is investigating both accidents in partnership with local law enforcement.

On the Skyline, numerous human triggered avalanches were reported:

Snow and Weather

General Conditions: Wind speeds really dropped off over the last 24 hours. They are from the east or southeast this morning and are light. Temperatures are around 10°F this morning, and it is lightly snowing. The new snow has greatly improved riding conditions. However, you will find many areas where you are sinking through all the new snow, then sinking deeper into the weak facets below. I noticed this both on skis and snowmachines. While ascending a low-angle slope, my track was trenching very deeply into the old facets. It felt like there was no base.

Mountain Weather: We'll see one last small storm impulse move through today that could add a couple more inches of snow. The wind should shift direction and blow from the west northwest and increase in speed a bit during the day. It should stay in the light to moderate speed categories. The storm moves out tonight and we'll see clear skies and warming temperatures this weekend.
