Problems
Wind Slabs
Potential for old lingering wind slabs
Winds have calmed to the Light range. Katabatic winds (Glacier outflow) will produce localized wind slabs.
Potential to wake up with day time warming on solar aspects
- If triggered the wind slabs may step down to deeper layers resulting in large avalanches.
Aspects: All aspects.
Elevations: Alpine.
Likelihood
Expected Size
Deep Persistent Slabs
Large triggers may wake up this layer IE: Cornices in combination with day time warming
- Be aware of the potential for full depth avalanches due to weak layers at the base of the snowpack.
- Avoid shallow snowpack areas where triggering is more likely.
Aspects: All aspects.
Elevations: Alpine, Treeline.
