Problems
Wind Slabs
20 cm new snow and moderate variable winds have created soft windslab in lees in alpine and treeline.
- Early season hazards such as rocks, trees and stumps are very prevalent
- Use caution in lee areas. Recent wind loading have created wind slabs.
Aspects: North, North East, East, South East, West, North West.
Elevations: Alpine, Treeline.

Expected Size
Loose Dry
20 cm unconsolidated snow not bonding to rain crust from Nov 30. Watch for sluffing in steep terrain.
- Be careful of loose dry power sluffing in steep, confined or exposed terrain.
Aspects: All aspects.
Elevations: Alpine, Treeline.
