Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • Unlikely • 1 - Small • Some steep slopes N, NE, E above 900 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • Possible • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 1000 masl

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • 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 • Possible • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • Unlikely • 2 - Medium • Few steep slopes N, NE, E above 1100 masl • Kantkornet er observert nede i det eldre snødekket og det skal mye til å påvirke dette laget. Q2 brudd, men ikke langt unna Q1..
