Avalanche warning for region Sunnmøre Saturday 20.03.2021

Avalanche Problems

• Wet slab avalanche • Poor bonding between crust and overlying snow • Within half a meter • The overlying slab is soft. • Easy to trigger • 1 - Small • Some steep slopes N, NE, W, NW above 1000 masl • Der våt løsnø ligger på glatt skare er den utglidningsfare. Den våte løssnøen binder seg ikke sammen, så forventet skredstørrelse er små.

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 3 - Large • Some steep slopes SW, W, NW above unknown masl • Fokksnøen ligger på noe som lignet kantkorn. Det var vanskelig å få til brudd (25 slag), men bruddflaten var glatt og flaket kompakt.

Avalanche Problems

• Wet slab avalanche • Poor bonding between crust and overlying snow • Within a meter • The collapsing weak layer is thin < 3 cm. • Very difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl • På glatt skare trur eg. Litt usikker på om det er verdt å ta med. Uansett veldig få stader trur eg.

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Few steep slopes NE, E, SE, S, SW above 700 masl • Er i ferd med å stabilisere seg godt.

• Loose wet avalanche • Loose snow • Spontaneous release • 1 - Small • Some steep slopes N, NE, E, SE, S, SW, W, NW above 600 masl
