Regions: Dogtooth, Goat, Retallack, Valhalla, West Purcell, Whatshan.

Choose small, low consequence slopes.

New storm and wind slabs will likely remain reactive to rider traffic.

Confidence

Moderate

Avalanche Summary

At the time of publishing we have not received any reports of avalanches but we suspect that storm slab avalanches have occurred throughout the region.

Snowpack Summary

By early morning on December 8th up to 30 cm of new snow may have fallen. This new snow will overlie a variety of surfaces including a sun crust on steep south aspects and Surface hoar on northerly aspects.

The mid snowpack is generally well settled, with an early November crust buried 80 to 130 cm deep.

Snowpack depths taper rapidly below treeline.

Weather Summary

Saturday Night

Mostly cloudy with up to 10 cm of snow expected. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -6°C.

Sunday

Mostly cloudy with up to 5 cm of snow expected. 10 to 30 km/h west ridgetop wind. Treeline temperature -5°C.

Monday

Clearing throughout the day with no snow expected. 15 to 30 km/h west ridgetop wind. Treeline temperature -6°C.

Tuesday

Mostly sunny with no snow expected. 15 to 25 km/h west ridgetop wind. Treeline temperature -8°C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Be careful as you transition into wind-affected terrain.
  • Be aware of the potential for large avalanches due to buried surface hoar.

Avalanche Problems

Storm Slabs

Storm slabs will likely remain reactive to rider traffic due to the surface hoar the new snow has fallen on.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 2.5
