Avalanche warning for region Sunnmøre Friday 06.01.2023

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • 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, SW, W, NW above 600 masl

Avalanche Problems

• Dry slab avalanche • Easy to trigger • 2 - Medium • Some steep slopes N, NE, W, NW above 600 masl • Fokksnö eller kant/dårlig bindning til skare, uansett vad det er så føyker det en del fra sør-sørøst. Tenker skred er lettest at løyse ut nær og i tregrensa hvor det er mest snö til transport nå g hvor det er ugunstigere lagdelning i snøen.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • 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. A big and identifiable crystal in the weak layer. • Easy to trigger • 1 - Small • Few steep slopes N, W, NW between unknown masl and unknown masl • Basert på profil här bara å føyk, små kant mot rundning. Mildvær neste dagene vill nok stabilisera det mesta i övre del av snödekket

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 • Few steep slopes N, W, NW between 900 masl and 700 masl • Det upplevs som att det er ju en veldig begränsad höjd intervall som skarelaget har ugunstig oppbygging runt seg. Over 850 forsvinner skaren og under 850 så er skaren så tjukk att det ikke har skedd oppbygging eller ikke går at påvirke det.

• Dry slab avalanche • 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. • Easy to trigger • 1 - Small • Few steep slopes N, W, NW above unknown masl • Nedføyket FCsf

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. • Easy to trigger • 2 - Medium • Few steep slopes N, S, SW, W, NW between 900 masl and 600 masl • Kanskje i alle aspekt. Der det er flak som har skapt dampsperre nokre dagar over varm skare. Kanskje mulig med str 3 i rette henget.

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Easy to trigger • 2 - Medium • Some steep slopes N, SW, W, NW above 600 masl • Ferske flak frå siste døgn

The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 3 - Large • Few steep slopes S, SW, W, NW between 1000 masl and 600 masl • Usikker. Men me har minst eit ferskt skred på det. No gjekk det som eit stort str 1 i eit heng som har produsert str 3 før. Så kanskje Max str 2 er riktig. Avhengig av flakstr og hengstr. Pluss dei andre faktorane som må til.
