Avalanche Summary
Storm slabs, and wind slabs in the alpine (size 1 to 2) were reported by local ski hills. Loose dry avalanches (size 1) were observed out of steep alpine terrain.
Snowpack Summary
15-35 cm settled storm snow (in the alpine) from past 4 days overlays crusts on all aspects except north (above 2400m) where it overlays dry snow.
The mid-pack Feb 3 persistent layer (crust/facet layer) and basal depth hoar remain the most prominent features in the snowpack but have been dormant with recent cool temperatures. These layers are a greater concern in thin snowpack areas on north slopes above 2300m.

Wed: 5-10 cm, mod to strong northerly winds. Freezing levels around 2000m.
