Avalanche warning for region Sunnmøre Friday 17.03.2023

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Very easy to trigger • 1 - Small • Some steep slopes • Skredstørrelse og utløsbarhet angitt pr nå. Dette vil endre seg raskt med den vinden som er meldt. pr nå virker SV og V mest utsatt, men terrenget styrer vinden når den ikke er sterkere enn dette, så vanskelig å angi mest utsatt sektor. har ikke vært lavere enn 900 og ikke høyere enn 1500.

• 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 • Har hatt drønn på turene de siste dager, men ikke mange og ikke veldig utbredt. Drønnene har hatt god forplantning. varierende utslag på tester. kan virke som om testene har mest respons i Nordlig sektor. varierende avstand fra overflaten til laget og varierende hardhet på overliggende snø. litt joker aktig oppførsel

Avalanche Problems

• 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. • Difficult to trigger • 3 - Large • Many steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl • Jag tror problemet er mer aktuellt fr 800moh og oppover. Det er för tjock skare lenger nede. Det er det mine obs sista tiden fra tregrensa har vist.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • A big and identifiable crystal in the weak layer. • Easy to trigger • 4 - Very large • Many steep slopes N, NE, E, SE, S, SW, W, NW below unknown masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Spontaneous release • 4 - Very large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl • Leformasjonar, skålformer, kjende skredbaner verst.

• 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. A big and identifiable crystal in the weak layer. • Spontaneous release • 2 - Medium • Many steep slopes N, NE, SW, W, NW above 600 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between crust and overlying snow • Within a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 3 - Large • Many steep slopes above unknown masl • Tror jeg

Vanskelig å løse ut i noen/mange eller naturlig i få (eller svært få)
