Forecast for the Salt Lake Area Mountains

Issued by Drew Hardesty on
Sunday morning, November 22, 2020
The avalanche danger is LOW and avalanches are unlikely.
The biggest concerns are slide-for-life conditions on the slick crusts and getting injured in the shallow snowpack by hitting rocks or other obstacles.
Tread lightly.

Special Announcements
Please do everything possible to avoid getting hurt for yourself and the greater good. As you decide where and how to travel in the backcountry, consider adding just a little extra margin of safety.

Weather and Snow
Skies are clear.
Inversions continue to strengthen with warm air moving in aloft ahead of tomorrow's "storm". Ridgetop temperatures are in the mid to upper 20s while trailheads and basins are mired in the cold pools of the teens.
Winds have also strengthened in the last couple of hours and are blowing 20-25mph from the southeast.

Snow surface conditions are something only a mother could love. 1-2' of snow sits on the ground at the mid and upper elevations, but it's beat up and hammered by wind, sun, and thermal crusts. Even the north facing slopes developed a thin crust from the scorching temperatures earlier this week. The south facing slopes should soften somewhat today with direct sun and warming temperatures.

For today, we'll have sunny skies with some high cirrus streaming in over the course of the day. Winds will be south to southwesterly, blowing 20-25mph. Daytime highs will again reach into the upper 30s to low 40s. A weak cold front tomorrow afternoon will usher in cooler temps and perhaps 1-3" of snow if we're lucky. Another weak storm arrives for Thanksgiving.

Description
The snow is generally stable and the danger is LOW. Pro observer Mark White summited Mount Superior on Thursday and reported the biggest hazard being slide-for-life conditions on nearly all aspects.
Slide for life conditions are conditions where one falls in steep terrain and unable to arrest on the slick crust below. Axes, whippets, crampons, etc can be helpful in these conditions. (Sorta gives a hint to the riding conditions, eh?)
Additional Information
Forecaster's Corner:
With clear skies and cold temperatures, the surface snow on the north side of the compass begins to become weak and faceted and generally lose cohesion (see Mark White video below). In the short term, this means you can buy a soft turn here or there, but in the long term it becomes a very real sliding surface for future avalanches whenever we see the next significant storms. At this point, the snow surfaces are quite variable, but it will be something to keep an eye on in the coming days (or weeks).
For the layperson, remember that ingredients for an avalanche often involve strong cohesive snow sitting above weak, sugary snow. Sugary faceted (angular) snow below.
