Avalanche Summary
We have received a few reports of storm slabs sliding on buried surface hoar.
We expect the frequency and size of avalanches to increase through the weekend.
Snowpack Summary
The 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. These layers are a concern with the new snow amounts forecasted.
The mid and lower snowpack remains generally well-settled and strong.
