Avalanche Summary

A size 1.5 skier triggered avalanche was reported on Wednesday on a north east aspect. This avalanche ran on the surface hoar described in the snowpack summary. Check out this Mountain Information Network report for more details.
A couple of small, natural wind slab avalanches were observed on westerly aspects by our field team on Thursday. These avalanches likely occurred over the past 24 to 48 hours.

Snowpack Summary

5 to 10 cm of previous storm snow overlies  old wind affected snow, wind slab and the early November rain crust depending on aspect.

On sheltered features a new surface hoar layer is down up to 20 cm. The early November crust is buried around 60 cm deep and may have small facets above it in these locations.

At treeline there is a snowpack depth of 60 to 80 cm. Snowpack depth tapers with elevation to around 30 cm at valley bottoms. Many early season hazards are just below the surface below treeline.

Weather Summary

Friday Night
Mostly clear skies. 10 to 20 km/h south ridgetop wind. Treeline temperature -7 °C.

Saturday
Sunny. 10 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Sunday
Mix of sun and clouds with 1 to 3 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -4°C.

Monday
Cloudy with up to 5 cm of snow at treeline and above. 50 km/h west ridgetop wind. Treeline temperature -1°C, freezing level rising to 1200 m.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Be cautious of buried obstacles, especially below treeline.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
