Snowpack Summary

Variable snowpack conditions in the alpine with up to 40cm in wind loaded areas on N - NE aspects. One or more rain crust  close to the ground up to 2,500m with weak faceted snow above and below. Recent storm snow is being transported near ridge tops. Early season conditions at all elevations. 

Avalanche Summary

Loose to size 2 in the alpine. Isolated soft slabs at upper elevations can be expected. No new field observations

Confidence

Due to the number of field observations on Wednesday

Avalanche Problems

Loose Dry

Heavy accumulations will heighten the avalanche danger in the alpine and gulley features at lower elevations. Soft storm slab development with the november rain crust as a failure plane on wind loaded terrain. Loose snow sluffing from steep terrain.
Be cautious of sluffing in steep terrain.Early season hazards such as rocks, trees and stumps are still visible.

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