Regions: Glacier.

Anticipate windslabs in open areas on all aspects. If more snow falls than forecasted, slabs will be easier to trigger.

Confidence

Moderate

Avalanche Summary

Natural avalanche activity has tapered off from the last storm and only a few isolated avalanches were observed through the highway corridor. However, skier triggered avalanches are still a possibility.

Snowpack Summary

Wind effect in the alpine & treeline elevation sits on a suncrust on solar aspects. Settled storm snow exists in sheltered locations.

The deep persistent weakness near the base of the snowpack consists of facets and a decomposing crust in some locations.

Weather Summary

Temperatures will gradually rise into the weekend and 14cm is forecast for Saturday afternoon and into Sunday. Winds are forecast to be moderate from the SW and a Alpine high of -12*C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.

Avalanche Problems

Wind Slabs

Variable winds have formed windslabs in the ALP and at TL. On solar aspects windslabs bury several crusts which may enhance reactivity.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2.5
