Conditions are tricky despite the moderate danger rating and sunny weather.

A persistent weak layer and wind slabs remain a concern.

Confidence

Moderate

Avalanche Summary

Whumpfing near Zoa peak was reported on Saturday where there was a slab (stiff snow) over the weak layer. Small skier triggered sluffs were also reported in steep terrain on Saturday.

Snowpack Summary

Wind effect has been extensive, and wind slabs can be found on various aspects extending well into treeline features.

Up to 5 cm of new snow that fell Friday night is adding to 20 to 60 cm of old snow overlying a weak layer that developed in late January. In many areas, this layer consists of a hard crust. However, on shady, upper-elevation slopes, the new snow may be resting on faceted grains or surface hoar.

A crust from December is buried 80 to 120 cm deep and may have facets around it in shallow areas. Otherwise, the lower snowpack is well consolidated.

Weather Summary

Sunday Night

Clear skies. 10 to 20 km/h north ridgetop wind. Treeline temperature -16 °C.

Monday

Sunny. 20 to 40 km/h northeast ridgetop wind. Treeline temperature -17 °C.

Tuesday

Sunny. 20 to 40 km/h north ridgetop wind. Treeline temperatures -8 °C.

Wednesday

Sunny. 10 to 20 km/h northeast ridgetop wind. Treeline temperatures -10 °C.

Terrain and Travel Advice

  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.

Avalanche Problems

Wind Slabs

Recent wind varied in direction, so watch for wind slabs on all aspects. Be cautious transitioning into wind affected terrain.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Persistent Slabs

A weak layer of facets/surface hoar/crust are buried up to 60 cm deep. Avoid areas where the snow feels stiff or slabby.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely

Expected Size: 1 - 2.5
