Avalanche warning for region Lyngen Friday 21.02.2020

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The overlying slab is soft. • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, W, NW above 300 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Easy to trigger • 2 - Medium • N, NE above 300 masl

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 overlying slab is soft. • Easy to trigger • 2 - Medium • Few steep slopes N, W, NW above 300 masl • Sterk vind gjør at de fleste steder blir avblåst, snøen legges igjen i få leområder.

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 N, NE, 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. • Very difficult to trigger • 2 - Medium • Many steep slopes N, NE, E, SE, S, SW, W, NW above 400 masl • Dette er IKKE et skredproblem i dag, men bør følges med på fremover. Kan være frekkere der snødekke er tynt.

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. • Easy to trigger • 1 - Small • Some steep slopes N, NE, NW between 1000 masl and 400 masl

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within a meter • The collapsing weak layer is thin < 3 cm. • Easy to trigger • 1 - Small • Some steep slopes N, NE, E, NW between 1000 masl and 400 masl

Avalanche Problems

• 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. • Very difficult to trigger • 2 - Medium • Few steep slopes above 1000 masl • Svagt lag av nysnø dypt i snøpakken. Ingen naturlige skred er observert på dette laget.

• Loose dry avalanche • Loose snow • Easy to trigger • 1 - Small • Many steep slopes N, NE, E, SE, S between 1800 masl and 600 masl
