Another system Friday afternoon bringing wind and some snow will bump up the hazard, depending on it's intensity. Lot's of snow available for transport, expect slab development and naturals to occur tomorrow afternoon.
Weather Forecast
Friday afternoon another system bringing moderate SW wind and snow forecast range from 5-20 cm. This will bump up the hazard tomorrow. Clearer weather Saturday and cooler temps to follow Sat night.
Snowpack Summary
30-50 cm of storm snow at tree-line along the continental divide. Very little wind effect as of yet... Easy-moderate shears at storm snow interface and mod shears down 60 cm on Nov 6 crust.

Avalanche Problems
Wind Slabs
Lots of snow available for transport. Expect slab development with system arriving tomorrow afternoon. Depending on intensity of snow transport and amount of new snow, the hazard will climb to CONSIDERABLE & possibly HIGH for Friday late afternoon.
- Avoid freshly wind loaded features.
- Avoid areas with overhead hazard.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Likely
Expected Size: 1 - 3
Persistent Slabs
Another full depth release observed on the glacier on Monarch pk (near Sunshine), NE aspect, 2800 m, size 2. With more loading, we may see this layer become more active elsewhere in the region.
Aspects: North, North East, East, South East.
Elevations: Alpine.
Likelihood: Unlikely - Possible
Expected Size: 1 - 3
