Avalanche Summary

There has been no recent avalanche activity reported in the previous few days. If you do observe an avalanche, consider posting a MIN.

Snowpack Summary

10 to 15 cm of new snow has accumulated on various surfaces, including a melt-freeze crust on solar slopes, hard wind-affected surfaces, or faceted snow and surface hoar on shady slopes.

At treeline, there are at least two temperature crusts within the recent storm snow down approximately 45 cm

A weak layer of facets and a crust from early December is buried 60 to 150 cm deep on all aspects up to 1750 m. This layer has not produced recent avalanche activity or test results and is not currently a concern.

Snow depth varies from 100 cm at highway elevations to over 200 cm in the alpine.

Weather Summary

Saturday Night

Mostly cloudy with 0 to 1 cm of snow. 10 to 20 km/h east ridgetop wind. Treeline temperature -8 °C.

Sunday

Mix of sun and clouds. 20 to 30 km/h southeast ridgetop wind. Treeline temperature -8 °C.

Monday

Mainly cloudy with isolated flurries. 10 to 20 km/h south ridgetop wind. Treeline temperature -7 °C.

Tuesday

Terrain and Travel Advice

  • Keep your guard up as storm slabs may remain sensitive to human triggering.

Avalanche Problems

Wind Slabs

10 -15 cm of new snow and elevated southwest wind will be forming fresh wind slabs in leeward terrain features through Saturday morning. Natural and human triggering is likely.

Aspects: North, North East, East, South East, North West.

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 2

Storm Slabs

Aspects: All aspects.

Elevations: Treeline.

Likelihood: Likely

Expected Size: 1 - 2.5
