Terrain and Travel Advice
- Watch for fresh storm slabs building throughout the day.
- Storm slab size and sensitivity to triggering will likely increase through the day.
Problems
Storm Slabs
Fresh snow and moderate to strong winds will be creating a new slab. This will be sitting on (yet another) weak layer of facets, expect this to be most reactive in immediate lee features. As the storm progresses the storm slab will become more widespread and reactive.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Persistent Slabs
20-50cms of snow overlays a buried persistent weak layer. This weak layer consists of surface hoar, facets and/or a suncrust. It will be most reactive where there is a settled, cohesive slab on top of a crust.
Aspects: All aspects.
Elevations: Alpine, Treeline.
