Forecast for the Salt Lake Area Mountains

The avalanche danger is LOW.
Sluffing is possible in steep northerly terrain and pockets of wind slab exist in isolated areas. Remember that risk is inherent in mountain travel and getting caught in a small avalanche in radical terrain could lead to disaster.

Weather and Snow
We're getting traced to death. Most areas picked up yet another trace of snow overnight. We might see yet another trace of snow this morning.
In the central Wasatch, I generally look at 20-25 weather stations in the morning and none of them are above zero. Many of them are -5°F or below. Winds are a little gusty (30-35mph gusts at 11k) from the west northwest with a little ripple (I hesitate to call it a 'storm') moving through this morning, but northwest winds should be 10-15mph for the day. At most.
Look for clearing skies by midday, light northwest winds, and temperatures that struggle into the single digits up high, the low teens down low.

The Alta Guard has been keeping monthly snow numbers since 1944/1945. January snow totals were 21" and 4.07" snow water equivalent. Average for January is 91"/8.6"SWE. Year to date numbers are 184"/21.22"SWE.

There is a beautiful book, written by the French aviator Antoine de St. Exupéry, called Wind, Sand, and Stars. Part of it details a time when his plane crashed in the Libyan desert. I think it was 1935. With little water between them, it wasn’t long until he and his navigator began experiencing visual and auditory hallucinations. Mirages appeared on the landscape, though they were always just out of reach. It’s a little like looking at the weather models these days…
Recent Avalanches
No new avalanches were reported yesterday, but two avalanches of interest have been reported in the last week:
  • Monday there was one report of a small human-triggered soft slab of wind drifted snow in Upper Lambs Canyon. This avalanche was on an east aspect on a 32° slope at 8,700' on a heavily wind-loaded slope, no one was caught or carried.
  • On Sunday, a catch-and-carry on the Catcher's Mitt on Kessler where a skier triggered a sluff in the weak surface snow on a steep, 40° slope. The skier was briefly caught and carried over a 10' cliff band and fortunately stopped short before going over a 30' cliff. I encourage you to read through this honest, well-described account of how getting caught in a small avalanche can be consequential in steep terrain.

Description
Overall, the avalanche danger is LOW and normal caution exists. In isolated areas, you may encounter:
  • Fast and long-running sluffs in the trace new snow or the weak, dry snow on steep slopes on northerly aspects. Any new snow that has fallen overnight, and continues to fall throughout the day will bond poorly to old weak snow underneath and be increasingly sensitive. In confined and sustained terrain features, even 1-3" of new can pile up deeply, especially in terrain traps. While these sluffs won't entrain much snow, getting caught in one could be serious in consequential terrain. (See Sunday's catch-and-carry on Kessler.)
  • Pockets of fresh wind drifted snow along exposed ridges and in open terrain at the mid and upper elevations. One to three inches of new snow can easily be blown into wind drifts two to six inches thick. Although drifts will be shallow and not very wide, wind drifts may be sensitive if they have formed on top of weaker snow underneath. (See small soft slab of wind drifted snow in Upper Lambs Canyon.)
Evaluate each slope and look for any signs of instability such as cracking in fresh wind drifts or long-running sluffs in steep terrain.
Additional Information
A couple of considerations for today -
Temperatures are below zero with wind chill at -20°F. Any injury or broken gear could lead to prolonged exposure, particularly if you're waiting on a rescue.
Serious slide for life conditions exist on bullet-proof wind and suncrusts. An axe or Black Diamond whippet ski pole could come in handy today.
