Weather Forecast
Avalanche Summary
No new avalanches observed.
Snowpack Summary
Evidence of widespread wind slabs at tree line and above. The lee features and cross loaded gullies are especially looking fat from last week's wind events. The November crust is down 40-100cm and is producing anywhere from moderate to no results. Â
Terrain and Travel
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
- Watch for areas of hard wind slab on alpine features.
Problems
Wind Slabs
Hard windslabs are widespread in alpine areas and even down into treeline. Listen for that drummy or hollow feel as an indication to be extra careful.
Aspects: North, North East, East, South East.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Persistent Slabs
Exposed, west facing alpine slopes have been stripped bare. This means the Nov 5 layer will be buried deeper than expected in some areas. In turn, this means that deeper layer will be more stressed with the additional load.
Aspects: All aspects.
Elevations: Alpine, Treeline.
