Regions

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

Monitor for signs of instability and dial back your terrain choice if you see older storm layers still reacting to tests or traffic. The best, safest snow is found in sheltered terrain.

Confidence

Moderate

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

Avalanche Summary

No new avalanches reported.

On Wednesday, explosives control in the Duffey Lake corridor produced size 2 storm slab results. On the Hurley, 10 - 30 cm storm slabs became touchy to skier traffic in steep terrain, propagating far but with relatively low destructive potential.

Snowpack Summary

Roughly 15 to 20 cm of new snow overlies a wind affected upper snowpack with wind slabs of varying age and reactivity in lee features, and exposed rock or December crust in open terrain.

Up to 110 cm of settling snow sits on the mid-December crust over wet snow. This forms the basal snowpack to about 2200 m. Above this elevation, a deeper crust with associated facets, formed in mid-November, can be found just off the ground.

Weather Summary

Friday Night
Mostly clear skies. 1 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -16 °C.

Saturday
Sunny. 20 km/h west ridgetop wind. Treeline temperature -15 °C.

Sunday
Mostly cloudy. 1 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -10 °C.

Monday
Mostly cloudy. 2 to 5 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -6 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.

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.
