Avalanche warning for region Lyngen Thursday 11.03.2021

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. • Easy to trigger • 2 - Medium • Some steep slopes • Lett å løse ut der flaket er mykt, vanskelig det flaket er hardt.

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Easy to trigger • 2 - Medium • Some steep slopes N, NE, NW

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. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Many steep slopes N, NE, E, SE, S, SW above 700 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 1 - Small • Some steep slopes NE, E, SE above 300 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Many steep slopes N, NE, E, SE, S, SW, W, NW above 600 masl • Høyde usikker, profil gravd på 900 moh, men kjapptester(staver, rask graving) tyder på at samme lag også finnes lenger ned på fjellet. Skal en god del til før det bryter, laget er utbredt og på feil sted kan det det gå store skred.

Avalanche Problems

• 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). A big and identifiable crystal in the weak layer. • Easy to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 500 masl • lett å løse ut der snødekket er tynt. Vanskelig eller krever stor tilleggsbelasting der overligende snødekket er tykk

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Difficult to trigger • 2 - Medium • Some steep slopes NE, E, SE, S, SW above 300 masl • Fokksnøen har begynt å stabilisere seg

Avalanche Problems

• 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. • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, SW, W, NW above 400 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 600 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 3 - Large • Few steep slopes E, SE, S, SW, W above 500 masl • Det er tydelege svake lag med kantkorn og begerkrystallar, og desse har gitt skred i området i helga. Dybda til laga og hardheit på overliggande flak varierar mykje og difor varierer det også kor lett det er å løyse ut skred. Mange stadar vil det vere vanskeleg, men potensielle skred kan bli store.
