Snowpack Summary
On Thursday 10 cm of new snow at tree-line has fallen on 10 cm of moist snow. Rain soaked snow below tree-line will start to form a supportive crust by Friday. Below tree-line travel will be challenging has temperatures lower. The mid to lower snowpack is generally rounded and well bonded.
Avalanche Summary
No new natural avalanche observed on Dec 02.
Avalanche control on Dec 01 produced many avalanches up to size 3.5, some reaching valley bottom. Avalanches started moist and ended wet. Natural activity has backed off as the storm leaves the region and temperatures start to cool.
Confidence
Due to the number of field observations
Avalanche Problems
Storm Slabs
New storm slabs are present at tree-line and above. Strong/extreme south-west winds created slabs over 1m thick. Slabs will continue to gain strength has temperatures cool.
- Be wary of large open slopes that did not previously avalanche.
- New snow will require several days to settle and stabilize.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2.5
Wind Slabs
Watch for wind slabs on lee and cross-loaded features. Strong to extreme winds from the south-west have moved snow.
- Watch for Wind Slabs low on slopes, and in usually sheltered terrain, due to previous extreme winds.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 1 - 2.5
