Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

Temperatures have been unseasonably warm, leading to moist surface snow on sunny aspects which can become unstable during the heat of the day. Where a re-freeze has occurred, a crust now exists. Recent storm snow appears to bonding well. A facet layer which formed in mid-January has gained strength. It showed hard, resistant planar results in a compression test at treeline in the Hankin area on Sunday.

Avalanche Problems

Cornices

Cornice fall could trigger an avalanche on the slope below. Isolated wind slabs also exist.

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

Elevations: Alpine.

Likelihood: Likely

Expected Size: 1 - 5

Loose Wet

Warmth and sunshine can trigger loose wet avalanches, particularly in steep, south-facing terrain.

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

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 4
