Avalanche warning for region Salten Wednesday 21.12.2022

Avalanche Problems

• Dry slab avalanche • Buried weak layer of surface hoar • Within a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 1 - Small • Some steep slopes N, NE, E, SE, S, SW, W, NW between 600 masl and 400 masl

• Buried weak layer of faceted snow beneath a crust • Within a meter • The overlying slab is soft. • N, NE, E, SE, S, SW, W, NW above 400 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited 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 SW, W, NW between unknown masl and unknown masl • Skrdproblemet er mest til stede i skoggrensa fra SV-NV, der vinden har bygd opp flak. Jeg valgte noen heng, da jeg synes det stemmer best i dette området og da får jeg fg 2. Men mulig det har kommet mer snø andre plasser. Virker som snøen binder seg godt.

• Dry slab avalanche • Buried weak layer of surface hoar • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW between 500 masl and unknown masl • Usikker om det var begerkrystaller eller overflaterim, men antar overflaterim. Fant disse bare litt under skoggrensa (en egen obs litt lenger ned) så antar at det er blåst bort lenger oppe.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within half a meter • The weak layer collapses easily and clean (easy propagation). The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Many steep slopes N, NE, E, SE, S, SW, W, NW above 400 masl • Dette er nok ikke et problem nå. Det må endel kraft til på ECT for å skape brudd (ECT27/ECT30+), men kantkorna er der og vil bli der inntil mildvær trenger ned i dekket.

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • Easy to trigger • 2 - Medium • Few steep slopes N, NE, SW, W, NW above 400 masl • Det er lite snø og jeg forventer ikke store områder ved vindtransport. Skredstr 2 i få bratte heng.
