Forecast for the Salt Lake Area Mountains

Dave Kelly
Issued by Dave Kelly for
Monday, January 23, 2023
The avalanche danger is MODERATE on upper-elevation slopes where you may trigger small wind-drifted snow avalanches. The avalanche danger is LOW on mid and lower elevation slopes where there is less wind-drifted snow.

Don't get caught in any avalanche regardless of size in a place where you don't want to go; such as over a cliff band, or through a stand of trees.

Small loose dry avalanches are possible in steeper terrain at all elevations.

Weather and Snow
Under clear skies temperatures are in the single digits F. Winds are primarily blowing from an easterly direction 30 gusting to 50 MPH at the highest ridgelines and 10 gusting to 20 MPH at the 9,000' ridgelines. Mountain operations teams reported 1-2" of new snow in the last twenty-four hours. For today, winds will blow strong from the east before decreasing in speed and turning more northerly. Skies will be partly cloudy with mountain temperatures 19-23 F. No new snow is expected today.

Looking ahead, cold northwest flow with a chance for light snow on Tuesday.

UAC Forecaster Greg Gagne's observation from Neffs Canyon talks about the weakening of the surface snow. He was able to initiate small loose-dry avalanches in the top 4" of the snowpack. Any new wind-drifted snow that lands on this weak surface snow will be a place where a rider could easily trigger an avalanche.
Recent Avalanches
There were no reports of avalanche activity from the backcountry yesterday. On Saturday there were reports of wind-drifted avalanches in upper elevation terrain. Catch up on backcountry observations HERE.

Description
Areas of wind-drifted snow will be more sensitive today than yesterday with winds now blowing from the east. These areas of wind-drifted snow will be easily recognizable as you will see smooth and rounded deposits. Look for clues of instability such as cracking and avoid steep slopes where you may trigger soft or hard slabs of wind-drifted snow. Cornices will be sensitive today and I would avoid traveling underneath these cornices or close to the edge of corniced ridgelines.

Additional Information
Are you snowpack curious? Wondering how the Persistent Weak Layer went from Zero to Hero?
Well, then, you came to the right place! Please join Craig Gordon at 6:00 pm Monday, January 23rd, in Park City at the Kimball Junction Library for a State of the Snowpack presentation. It's going to be informative, educational, and quite possibly entertaining!
