Low

Avalanche Summary

Small windslabs in leeward areas in the high alpine and exposed areas at upper treeline are possible.

Snowpack Summary

Avalanche Problems

Wind Slabs

Minimal reports from the alpine, but previous small wind slabs have been reported by ice climbers. New snow and wind may increase the likelihood of encountering and triggering these.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5
