Watch for fresh wind slabs on steep slopes in the alpine and at treeline

The best riding will be in sheltered terrain

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported since Friday, when several natural storm slabs were reported on north and west aspects in the alpine and at treeline.

Reports are limited but this suggests conditions are improving and reactivity may linger in specific features.

Snowpack Summary

30 to 50 cm wind affected snow sits at the surface.

A surface hoar layer is now buried 40 to 70 cm deep. This layer is spotty and hard to find. It may be found and triggerable in very sheltered treeline and alpine features. Where there isn't surface hoar, there is likely a crust.

There are no current concerns deeper in the snowpack. HS at treeline measures 120-150 cm.

Weather Summary

Sunday Night

Mostly cloudy, up to 5 cm of snow. 30 to 40 km/h south ridgetop wind. Treeline temperature -5 °C.

Monday

Mostly cloudy with up to 8 cm of snow. 20 to 30 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Tuesday

Mostly cloudy with up to 10 cm of snow. 40 to 50 km/h south ridgetop wind. Treeline temperature -3 °C.

Wednesday

A mix of sun and cloud 40 to 50 km/h south ridgetop wind. Treeline temperature -3 °C.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.

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.
