Avalanche warning for region Voss Saturday 13.02.2021

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • Very easy to trigger • 2 - Medium • Few steep slopes N, S, SW, W, NW above 700 masl • Vind fra øst har tidligere dannet flak på løsere kantkorn, disse er fortsatt svært lett å løse ut. Men trolig få heng.

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within a meter • Difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl • Lengre ned finnes eldre kantkorn fra starten av januar , skal mer til for å løsne.

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. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Few steep slopes SW, W, NW above unknown masl

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. • Difficult to trigger • 2 - Medium • Undersøkelse er gjort i et S-SØ heng

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. A big and identifiable crystal in the weak layer. • Easy to trigger • SE

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Over one meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • SE

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 1 - Small • Some steep slopes E above unknown masl • Det finnes svake lag, men faren er der det ligger vindtransportert snø. Og lite snødekke. Kun observasjon på østlig side.

Avalanche Problems

• Loose dry avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Easy to trigger • S, SW • Tydlig bundet lag over og under det svake laget beskrevet i testen. Ved litt belastning kom drønn fra det svake laget.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • Unknown • NE, E • Øverste 10 cm er DF, resterende 40 cm er fast. Underliggende snø er fast.

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. • Difficult to trigger • 3 - Large • Many steep slopes N, NE, E, SE, S, SW, W, NW above unknown masl • Denne vurderingen tar utgangspunkt i svakt lag på LBT langt nede i dekket. Dette laget skal mye til å påvirke, mens det finnes kantkorn lengre opp som ligger under tynne flak. I vestlige heng med mer fokksnø i toppen vil det være sannsynlig å løse ut skred med liten tilleggsbelastning
