Avalanche Problems

Storm Slabs

33 cm of storm snow in the past 36 hrs has resulted in an instability over a crust and old snow. This has been observed in a small avalanche cycle with size 2 to 3 avalanches early Nov 7 and shows in stability tests at treeline.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 3

Wind Slabs

Strong south winds up to 60 km/h over the past 3 days has created windslab in alpine and upper treeline elevations on leeward terrain.

Aspects: North, North East, East.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 3
