Avalanche warning for region Trollheimen Friday 14.01.2022

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. • Spontaneous release • 3 - Large • Many steep slopes N, NE, E, SE, S above 700 masl • Legger seg opp store mengder snø i leheng. Naturlig utløste skred må forventes

• Wet slab avalanche • Water pooling in/above snow layers • Within 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. • Spontaneous release • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW

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 • 2 - Medium • NE, E, SE above unknown masl • Gjelder for nå-situasjonen, stigende temp og økende regn vil påvirke dette ila kort tid.

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • 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. • Difficult to trigger • 2 - Medium • Few steep slopes NE between 1500 masl and 1100 masl

• Dry slab avalanche • Poor bonding between crust and overlying snow • Within a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • 3 - Large • Some steep slopes SE between unknown masl and 1100 masl
