Problems
Wind Slabs
Moderate to Strong SW wind will create fresh wind slab on sunday evening. These new wind slabs sit over a variety of firm surfaces including wind effected snow and sun/temperature crusts. Expect the reactivity to increase throughout the day Monday.
- Use caution in lee areas. Recent wind loading has created wind slabs.
- Watch for stiffer feeling snow. Avoid areas that appear wind loaded.
Aspects: North, North East, East, North West.
Elevations: Alpine, Treeline.

Expected Size
Loose Dry
Wind sheltered terrain will have 10-15 cm of dry snow sitting over pervious firm surfaces. Expect small, loose dry avalanches in steep sheltered terrain.
- Be careful of loose dry sluffing in steep, confined or exposed terrain.
Aspects: All aspects.
Elevations: Alpine, Treeline.
