Avalanche warning for region Lyngen Thursday 18.03.2021

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). The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW between 1100 masl and 500 masl

• Dry slab avalanche • Buried weak layer of faceted snow near surface • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Very difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl

Avalanche Problems

• Dry slab avalanche • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 3 - Large • Many steep slopes N, NE, E, SE, S, SW above 700 masl

Avalanche Problems

• Loose dry avalanche • Loose snow • Spontaneous release • 1 - Small • Many steep slopes S, SW • Veldig små.

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Over one meter • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Easy to trigger • 1 - Small • Few steep slopes above 400 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between crust and overlying snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). The overlying slab is soft. • Difficult to trigger • 2 - Medium • Some steep slopes NE, E, SE, S, SW between 600 masl and 300 masl • Mulig problemet kan finnes både høyere og lavere, men tror øverste grense er så høyt mildværet gikk 14.mars.

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. • Easy to trigger • 2 - Medium • SE, S, SW, W, NW • Lett å løse ut der det er et fersk vinflasker snø. Vil stabilisere seg saktere i høyden. Veldig gunstig forhold for vindtransport av snø foe øyeblikket.

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 • Har ikke observert noe faretegn, og det er vanskelig å påvirke dette lagret, men det fins i snødekket og det går nok ikke bort.
