Avalanche warning for region Voss Wednesday 10.02.2021

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 • Some steep slopes S, SW, W, NW above 800 masl • Nedføyka rim og delvis nedbrutt snø under delvis hard fokksnø. Det er og små kantkorn innimellom. Der snødekket er hardt nok, men ikkje for hardt er det lett å løyse ut fokksnø flak. Vanskelig å anslå skredstørrelse, men tipper str 2 til kanskje 3.

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • Difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 600 masl

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 • Unknown • Some steep slopes • Kankornlaget er i alle himmelretninger. Avhengig av vindtransportert snø over

A big and identifiable crystal in the weak layer. • Easy to trigger • Unknown • Some steep slopes N, NE, E, SE, S, SW, W, NW • Kantkornlag i alle sider, varierende dybde, vindpåvirkning som avgjør om dette blir et problem.

The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • Unknown • Some steep slopes • Kantkorn laget finnes sannsynligvis over alt i området. Vindtransportert snø inn i le soner, over dette laget vill kunne skape ett skredproblem

Det som er avgjørende er om det er fokksnø eller vindtransportert snø over.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within half a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Very difficult to trigger • Some steep slopes N, NE, E, SE, S, SW, W, NW above unknown masl • - ingen stabilitetstest gjennomført, men snøpakken er hard og virker solid.

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • Some steep slopes N, NE, E, SE, S, 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 • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 1000 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Over one meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • Unknown • Few steep slopes SW above 1200 masl • Snøprofil vil variere fra sted til sted lokalt. Ikke gjort snøprofil i brattere terreng på samme sted.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • Very easy to trigger • 3 - Large • Some steep slopes N, S, SW, W, NW above 700 masl • Østavind har laget flak oppå løse kantkorn. Svært lett å løse ut. Tydelige faretegn som drønn, sprekker og fjernutløsning. Alt jeg gikk på av flak drønna.

• 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 • Eldre kantkorn finnes i alle himmelretninger men vanskelig å løse ut og trolig få plasser.
