Snowpack Summary
At higher elevations, much of the surface was eroded to the January 18th crust by the W high winds of last weekend. New snow received afterwards also blew off and very little leeward accumulation was observed. Below the treeline, 35 to 45 cm of wind-affected snow was found on top of the decaying crust.
In general, snowpack heights ranged from 70-90 cm in the valley to 100-150 cm in the mid-mountain.
Weather Summary

Terrain and Travel Advice
- Closely monitor how the new snow is bonding to the crust.
Problems
Wind Slabs
The 10 cm of snow and moderate to strong southeasterly winds on Friday could form new wind patches. Since many surfaces are icy, they may not have very good traction.
Aspects: North, South West, West, North West.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Persistent Slabs
A layer with slab properties overlies a layer of facets over the January 18th crust. The likelihood of triggering an avalanche on this interface is unlikely, but the consequence of an event on this layer would be a large avalanche. Keep an eye out in areas where the snowpack is thinner.
Aspects: North, North East, East, South East.
Elevations: Treeline, Below Treeline.
