Choose small, low consequence slopes.

Storm slabs are likely sensitive to rider traffic.

Avalanche Summary

No new avalanches have been reported.

Reports have been limited. Please consider submitting your observations to the Mountain Information Network.

Snowpack Summary

By the morning of November 29 up to 30 cm could overlie variable snow surfaces, including small facets and/or surface hoar in sheltered areas and heavily wind-affected snow in exposed terrain.

Two surface hoar layers can be found in the mid pack, one down 30 to 55 cm and another down 45 to 85 cm at treeline.

A rain crust from early November is buried 60 to 90 cm deep and seems to be bonding well to overlying layers.

Alpine snow depths vary greatly across the region and from aspect to aspect.

Weather Summary

Thursday Night

Cloudy with up to 15 cm of snow expected. 40 to 70 km/h southwest ridgetop wind. Treeline temperature -4°C.

Friday

Cloudy  with up to 5 cm of snow expected. 30 to 60 km/h southwest ridgetop wind. Treeline temperature -6°C.

Saturday

Cloudy with 15 to 25 cm of snow expected. 30 to 60 km/h southwest ridgetop wind. Treeline temperature -12°C.

Sunday

Cloudy with 10 to 20 cm of snow expected. 40 to 70 km/h south ridgetop wind. Treeline temperature -1°C, potential for a temperature inversion with colder temperatures at valley bottom.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Don't let storm day fever lure you into consequential terrain.
  • Be aware of the potential for larger than expected storm slabs due to buried surface hoar.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.

Avalanche Problems

Storm Slabs

A couple of concerning weak layers exist in the top meter of the snowpack.

Storm slabs could step down to these layers resulting in larger avalanches.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 3
