Forecast for the Salt Lake Area Mountains

Issued by Nikki Champion on
Thursday morning, April 20, 2023
The snowpack is generally stable and the avalanche danger is LOW. The two main concerns are isolated pockets of wind-drifted snow in exposed terrain at the upper elevations, and sluffing within the few inches of new snow at the surface in steep terrain.

Risk is inherent in mountain travel; getting caught in even a small avalanche could have a detrimental outcome.

Special Announcements
The last daily forecast will be Sunday, April 23. We will provide intermittent updates with any storm until Sunday, May 7th and will continue posting backcountry observations until then.
The UAC is sad to report that a resident was killed by a roof avalanche on Monday, April 17th, in the Town of Brighton. A report is available HERE. Many communities still have a lot of snow on roofs that could produce similar avalanches.
Weather and Snow
Under overcast skies, it is lightly snowing in the mountains with no measurable precipitation as of 6AM. Trailhead temperatures are in the mid-teens and the highest weather station temperatures are hovering below 10 ˚F. Winds are lightly blowing from the west at the 9,000' ridgelines and blowing 20 MPH gusting to 38 MPH at the highest ridgelines.

Today will remain overcast with light snowshowers throughout the day. Temperatures will climb into the upper 20s and low 30s˚ F. Wind speeds will increase throughout the day blowing from the west-northwest at 20 MPH at the 9,000' ridgelines and blowing 20-30 gusting to 50 MPH at the highest ridgelines. There could be 2-5" of new snow in the mountains by this evening.

Another system moving through the area could bring more snowfall Friday.
Recent Avalanches
We had no reports of avalanches from the backcountry yesterday. Find all avalanche and snowpack observations HERE.

Description
The snowpack is generally stable and natural and human-triggered avalanches are unlikely. In isolated areas, you may encounter:
  • Pockets of fresh wind drifted snow along exposed ridges and in open terrain at the upper elevations. The moderate to strong westerly winds from yesterday will have transported the new snow onto leeward aspects to form sensitive drifts that will be reactive to riders today. Rounded pillows of new snow that crack or collapse on approach are sure signs that the wind-drifts are sensitive and should be approached with caution.
  • Fast and long-running sluffs within the new snow on steep slopes. On slopes where the new snow falls on top of hard crusts, getting caught and carried in a loose sluff could have serious consequences in steep, rocky terrain as you may be unable to self-arrest on any slick surfaces underneath.
  • Cornices and roof-avalanches present a real danger today as well. Give both a wide berth.
