Avalanche Summary
On Sunday, there were a few large to very large (size 2 to 3) persistent slab avalanches that failed during the warm weather on southeast and northeast aspects.
As well as numerous small wet loose avalanches from steep slopes facing the sun.
Snowpack Summary
20 to 40 cm of soft snow has been redistributed by southwest wind. Scouring exposed areas and loading lee features. In sheltered areas, this snow may sit on a layer of weak surface hoar crystals.
Around 100 to 200 cm deep are buried weak layers from December. Consisting of crusts, facets, and/or surface hoar. These layers continue to produce large avalanches.
The lower snowpack is strong, with no layers of concern.
Weather Summary
Monday Night
Cloudy. 30 to 50 km/h west ridgetop wind. Treeline temperature -6 °C.
Tuesday
Cloudy with 5 to 10 cm of snow. 10 to 20 km/h west ridgetop wind. Treeline temperature -6 °C.
Wednesday
Mostly cloudy with 20 to 30 cm of snow overnight and 10 cm during the day. 20 to 40 km/h west ridgetop wind. Treeline temperature -8 °C.
Thursday
Mostly cloudy with 5 cm of snow. 15 km/h south ridgetop wind. Treeline temperature -11 °C.

Terrain and Travel Advice
- Avoid steep terrain that is rocky and thin.
- Avoid areas where the snow feels stiff and/or slabby.
- If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
Problems
Persistent Slabs
The weak layer from early December is of greatest concern in areas with shallow, thin-to-thick snowpacks and on wind-loaded north or east-facing slopes.
Aspects: All aspects.
Elevations: Alpine, Treeline.

Expected Size
Wind Slabs
Wind slabs may sit on a layer of weak surface hoar crystals and take longer than normal to heal.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
