Avalanche warning for region Sunnmøre Sunday 17.01.2021

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • Fant to lag nedføyket nysnø ett ca 3cm under snødekket og det andre ca 30cm. Hardheten på snødekket var ganske variert så vanskelig å si noe generelt om skredproblemet

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Some steep slopes NE, E, SE, S, SW above unknown masl

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • 2 - Medium • NE, E, SE, S, SW above unknown masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 1 - Small • Few steep slopes E, SE, S, SW above 600 masl

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within a meter • The weak layer collapses easily and clean (easy propagation). • Difficult to trigger • 3 - Large • Many steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl • Tjukkare svakt lag, mindre krystallar, hardare flak, Færre/ingen faretegn.

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW between 800 masl and 400 masl • I skogen og til et stykke over skogggrense.
