Snowpack Summary

Tuesday's moderate Northwest winds redistributed snow with soft slab formation possible on lee features. There was intense ridge top transport from the North in the alpine on Tuesday. Cold temps are promoting facetting throughout the snowpack. Nov12 crust down 45 to 90cm and found between 2100-2600m on all aspects.

Avalanche Summary

No new avalanches observed or reported.

Avalanche Problems

Loose Dry

Cold temps have weakened the snow clinging to steep terrain, and as a result shedding and sluffing should be expected.
Avoid travelling on ledges and cliffs where sluffing may have severe consequences.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Persistent Slabs

Although this layer has been dormant, it is still a concern and is widespread between 2100-2600m.
Be cautious in shallow snowpack areas where triggering is more likely.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 3
