Avalanche Summary
On Thursday, two large (size 2) wind slabs failed naturally on steep northeast aspects in the alpine.
Several natural and rider-triggered avalanches, up to size 2.5, were reported on the 18th and 19th of January. A number of these reports occurred on the weak layer from early December.
Snowpack Summary
Recent snow has been heavily wind-affected in exposed areas. A crust exists below 1250 m, making for challenging travel conditions.
A weak layer of facets and a crust from early December is buried roughly 50 to 100 cm deep.
Weather Summary
Saturday Night
Clear. 20 to 30 km/h northwest ridgetop wind. Treeline temperature -7 °C with a temperature inversion.
Sunday
A mix of sun and clouds. 20 to 30 km/h northwest ridgetop wind. Treeline temperature -4 °C with a temperature inversion.
Monday
Sunny. 20 to 50 km/h west ridgetop wind. Treeline temperature 0 °C, inversion breaking down.
Tuesday
Mostly cloudy. 15 to 30 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice
- Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
- If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
- A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
Problems
Persistent Slabs
A widespread crust with facets is buried 50 to 100 cm deep. Wind slabs may step down to this layer, producing large avalanches.
Aspects: All aspects.

Wind Slabs
Watch for steep convex rollovers, ridgetop entrances, and cross-loaded features.
Aspects: North, North East, East, South East, North West.
