A bit of snow combined with wind will keep wind slabs as the main concern at upper elevations.
Summary
Confidence
Moderate
Avalanche Summary
Avalanche activity over the weekend has been reported as natural and skier triggered wind slab avalanches to size 1 in the alpine and at treeline.
Snowpack Summary
New snow from last week combined with recent wind has formed new wind slabs in exposed alpine and treeline terrain. On solar aspects treeline and below, the new snow overlies a variety of crusts from recent warming, sun, and rain.
We continue to track early January and early December surface hoar and crust layers down 30 to 50 cm and down 80 to 130 cm, respectively. Both are considered unlikely to trigger.
Weather Summary
Monday Night
Mainly cloudy with scattered flurries, accumulation 3-8 cm. 30 to 50 km/h west and northwest ridgetop wind. Treeline high temperature -13 °C.
Tuesday
Mostly cloudy with isolated flurries, 2-5 cm of new snow. 30 to 60 km/h northwest ridgetop wind. Treeline high temperature -10 °C.
Wednesday
Mainly cloudy with scattered flurries. 20 to 40 km/h west ridgetop wind. Treeline high temperature -8 °C.
Thursday
Mainly cloudy with flurries, 5 to 10 cm of new snow. 30 to 50 km/h northwest ridgetop wind. Treeline high temperature -6 °C.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
- Recent wind has varied in direction, so watch for wind slabs on all aspects.
- Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
Problems
Wind Slabs
Recent wind slabs scattered across higher elevation terrain may remain sensitive to human triggering. Slabs may be most reactive where they have formed over a crust.
Aspects: All aspects.
