Avalanche Problems

Storm Slabs

30cm of snow in the past 4 days with moderate Southwesterly ridge top winds is creating storm slabs on lee aspects. Two size 2 soft slab avalanches were recorded from Northeasterly facing alpine terrain.

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 3

Wind Slabs

Recent storm snow is adding load to previous wind slabs and increasing their sensitivity to triggering. Recently recorded avalanche activity is stepping down to ground.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
