Avalanche warning for region Jotunheimen Thursday 27.02.2020

Avalanche Problems

• Dry slab avalanche • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 3 - Large • Many steep slopes N, NE, E, SE between 2000 masl and 1200 masl

Avalanche Problems

• Poor bonding between layers in wind deposited snow • Within half a meter • The overlying slab is soft. • Very difficult to trigger • Some steep slopes E between 1400 masl and unknown masl

Avalanche Problems

• Poor bonding between layers in wind deposited snow • Within half a meter

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • Difficult to trigger • 2 - Medium • Some steep slopes E between 1400 masl and unknown masl

Avalanche Problems

• Poor bonding between layers in wind deposited snow • Within half a meter • The collapsing weak layer is thin < 3 cm. • Very difficult to trigger • 1 - Small • Some steep slopes NE, E, SE between unknown masl and unknown masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within a meter • The weak layer collapses easily and clean (easy propagation). A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Some steep slopes NE, E, SE, S above unknown masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within a meter • Difficult to trigger • 3 - Large • Some steep slopes NE, E, SE, S between 1500 masl and 1000 masl

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 3 - Large • Some steep slopes NE, E, SE between 1200 masl and 900 masl • Observert av Paul Wyssen i dag etter obs av bruddkanter etter snøskredkontroll.
