Kernpunkte

This forecast is based on limited field observations. Careful terrain selection is recommended while gathering more snowpack information.

Lawinenprobleme

  • Storm Slabs

    Wahrscheinlichkeit
    Unlikely - Possible
    Größe

    Slabs may be more reactive in wind-exposed terrain and areas where the new snow has a weak bond with the underlying surface layer.

Confidence

Low - Due to the number of field observations

Avalanche Summary

No recent natural avalanches have been reported. Explosives have triggered small slab avalanches in ridge top lee features. We currently have limited observations in this region. Please submit your observations to the Mountain Information Network (MIN).

Snowpack Summary

A surface hoar/sun crust layer is buried under 15-30 cm recent snow. The surface hoar is more prevalent in sheltered areas and at treeline and below; the crust is found in exposed alpine terrain and solar aspects. The snowpack is supported by an unreactive basal crust/facet layer 15-25 cm above the ground. The total snowpack depth varies from 110-160 cm in the alpine, with snowpack depth decreasing quickly with decreasing elevation. In many areas, the below treeline snowpack is below threshold.
