Storm slabs are primed for triggering.
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.
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.
