Avalanche Forecast

Fair - Forecast snowfall amounts are uncertain

Cloudy overnight with developing northwest winds and alpine temperatures around -10. Overcast with snow starting late morning. Most areas should see 5-10 cm, and areas in the southeast may see enhanced precipitation as the arctic air dives south and collides with some warmer Pacific air. The snow should end by Tuesday morning when skies clear and the high pressure re-builds over the interior. Wednesday should be clear and cold with light winds.

Facetted surface snow has been reported to be sloughing in steep terrain. Isolated pockets of windslab have been reactive to skier triggering up to size 1.0.

There is quite a bit of variability across the region in regards to new snow amounts. The surface is also variable with everything from dry new snow, loose facetted snow, windslabs, to sun crusts. There is 5-30 cm of facetted new snow and surface hoar above the mid-February crust. The late-Jan crust/surface hoar layer (up to 100 cm deep) and the mid-January surface hoar (80-120 cm deep) are generally dormant, and chances of triggering these weaknesses have decreased. However, triggering may be possible with a large input such as cornice fall, or an avalanche stepping down, especially on slopes that see a lot of sun.
