Confidence
Problems
Wind Slabs
Previous SW winds and snow available to transport has resulted in wind slab formation. In sheltered location there could be isolated storm slabs.
- Minimize exposure during periods of heavy loading from new snow and wind.
- Use caution in lee areas. Recent wind loading have created wind slabs.
Aspects: North, North East, East, West, North West.
Elevations: Alpine, Treeline.

Expected Size
Loose Dry
If it is raining at lower elevations watch out for wet loose avalanches below tree line. Avoid ice climbs that are exposed to steep rocky terrain.
- Avoid terrain traps, such as gullies, where the consequences of a small avalanche could be serious.
- Use caution above cliffs where small avalanches may have severe consequences.
Aspects: All aspects.
Elevations: All elevations.
