Avalanche warning for region Lyngen Tuesday 17.03.2020

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 • 2 - Medium • Some steep slopes NE, E, SE • Hovedproblemet jeg finner i dag er nedføyket nysnø og eller lagdeling i fokksnøen. Fant ingen områder på min tur i dag der det var tydelig fokksnøskavler, men de finnes nok ved dette været. Det er da også et lag med nedføyket nysnø oppå skare. Dette sistnevnte problemet fant jeg ikke over skoggrensen

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S above 300 masl

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. • Spontaneous release • 2 - Medium • N, NE, E between 1800 masl and 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 collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • 1 - Small • Many steep slopes N, NE, E, SE, S, SW, W, NW above 400 masl • Sluff.

• Dry slab avalanche • Buried weak layer of new snow • Within a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • 1 - Small • Some steep slopes N, NE, E, NW above 400 masl

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • 2 - Medium • N, NE, E, NW between 1000 masl and 400 masl • Økende med mer vind. Mye snø tilgjengelig for transport.

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, E, SE, S, SW, W, NW above 200 masl • Har ikke vært så mye snø å vind her som var varslet . Fortsatt mulig å løste ut fokksnøe skred i noen bratte heng der det er fersk vindtransport snø

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Very difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 400 masl • Tror ikke at KK laget er aktiv ennå men bør følge med på det
