Regions

South Coast Inland, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

A spotty surface hoar layer exists, so investigate how the recent storm snow is bonding to underlying layers.

Test small features before committing to big terrain.

Confidence

Moderate

  • Uncertainty is due to the limited number of field observations.

Avalanche Summary

Several small (size 1) human-triggered storm slabs have been triggered in the top 20 to 30 cm over the past few days, potentially failing on recently buried crust and surface hoar layers.

Snowpack Summary

20 to 30 cm of new snow is found above 1300 m. This overlies a variety of layers, including a breakable crust on south-facing aspects, wind-affected snow on north-facing terrain, and surface hoar on sheltered features.

The mid-December crust is 90 to 150 cm deep, except on wind-scoured alpine features, where it could be on the surface. This crust is well-bonded to the snow above. Above 2200 m, this crust is absent, and a layer of facets and a crust from November is found at the base of the snowpack. These layers are not currently a concern.

Weather Summary

Wednesday Night

Partly cloudy. 1 to 4 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Thursday

Mostly cloudy. 0 to 1 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -9 °C.

Friday

Mostly cloudy. 2 to 4 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Saturday

Mix of sun and clouds. 0 to 1 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -2 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Use small, low consequence slopes to test the bond of the new snow.

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.
