Avalanche Summary
Several natural and human-triggered avalanches have been reported since Friday. Expect avalanche activity to continue through the forecast period.
Snowpack Summary
Up to 60 cm of new snow has fallen on a variety of old surfaces. There is surface hoar, more prevalent around treeline and below, a crust on sun-facing slopes, and 20 to 30 cm of low-density faceted snow in sheltered areas.
Dry January conditions have created a weak, faceted upper snowpack with multiple surface hoar and crust layers. The new snow will likely not bond well with these layers.
The mid and lower snowpack remains generally well-settled and strong.
