Forecast for the Salt Lake Area Mountains

Issued by Mark Staples on
Saturday morning, February 29, 2020
The avalanche danger is LOW on all aspects and elevations. Watch for small, wet-loose avalanches on steep, sunny slopes.
Slide for life conditions exist on some slopes. This means the snow surface is hard and icy and you might not be able to stop if you fall.

The UAC's Avy Awareness Auction is currently underway with tons of great gear, jewelry, artwork and experiences available. Visit the auction page HERE to help support the UAC's spring avalanche awareness and outreach efforts.

A new version of the UAC IOS application is now available on the Apple App Store. This version fixes many of the issues that occur when running IOS 13. Download it now!
Weather and Snow
Weather: Yesterday's high temperatures were generally in the upper 30s and low 40s F which were five to ten degrees warmer than the day before. Temperatures this morning are mostly in the mid 20s F but a few low elevation sites have temps in the teens and some mid-elevation areas have temps near 30 F.
Southwest winds increased overnight and are blowing 10-20 mph gusting 30 mph. Today should warm about as much as yesterday but partly cloudy skies should keep it from feeling too hot. High temperatures should reach the upper 30s and low 40s F again and the southwest winds will continue. Accumulating snow should arrive late tonight and deposit 1-3 inches by tomorrow morning when a cold front crosses overhead. Snowfall will continue Sunday through Monday morning with snow totals of maybe 8-14 inches.
Snow: There are a variety of snow surfaces currently although most slopes will have an ice crust this morning that should soften by mid morning. A combination of very warm weather yesterday and cloudy skies overnight may have kept limited the depth of the refreeze. This limited refreeze means that it won't take much warming today for the snow to turn wet. With the approaching clouds, it's hard to say if it will happen very early or not. Upper elevation slopes facing due north and untouched by winds in the last week have some dry recyrstallized snow. Some slopes scoured by winds have a very hard ice crust that formed February 7th.
Note on Alta Guard precipitation from Mark Saurer at UDOT: Unless we get a shot of snow tonight before 0400 Sunday, Feb totals will be 72.5" of snow and 10" of water (Feb average is 82" of snow and 7.3" of water). Year to day totals are 343" of snow with 35.96" water (average through Feb is 329.5" of snow and 30.44" of water).
Looking across the state, the snowpack is generally near or slightly above normal for snow water equivalent. For the full map of basins across the western U.S. go HERE. To see a map of how individual sites compare to normal, go HERE.

Description
Currently, avalanche conditions are generally safe. Avalanches are always possible, and the main thing to watch for today are small loose wet avalanches on steep, sunny slopes. Small and isolated wind slabs could be an issue, but I think these have all stabilized during the warm weather. Slide-for-life conditions exist on steep aspects that have been scoured down to the Feb 7 crust. These are icy conditions in which you would be unable to stop if you fell.
Looking ahead: With increasing winds and snow in the forecast, the avalanche danger will rise by Sunday morning. The most likely places for shallow soft slab avalanches of new snow will be slopes that currently have dry, recrystallized snow on top of the February 7th crust. These are generally slopes shaded from both sun and wind.
