Avalanche Summary

No new avalanches were reported on Wednesday, however, there is currently very limited data for this region. Please report your observations to the Mountain Information Network (MIN).

Snowpack Summary

Observations are limited in this region. Old wind slabs in wind affected alpine terrain, especially below ridge tops. The crust formed in mid-November is down 60-80 cm. Average snowpack depths at treeline are 70-150 cm with generally less snow in the southern portions of the region. Early season hazards such as stumps, rocks, and open creeks remain the primary hazards below treeline.

Avalanche Problems

Wind Slabs

Strong winds and light snow may create fresh wind slabs in the alpine.
Use ridges or ribs to avoid pockets of wind loaded snow.Avoid areas where the snow feels stiff or 'slabby'.Be cautious as you transition into wind affected terrain.

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2
