Avalanche warning for region Indre Fjordane Friday 10.03.2023

Avalanche Problems

• 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. • Difficult to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW above 600 masl • Stader der det har vore vind nok til at det kan finnast lagdelingar i fokksnø.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 3 - Large • Many steep slopes N, NE, E, SE, S, SW, W, NW above 600 masl • Utbredelsen av skarelag og små kantkorn mener jeg er stor. Det er vanskelig å løse ut noe på dette ettersom bruddet ikke sprer seg men hvis det går skred på kantkorn under skare må det kunne bli størrelse 3. Enten mange heng og vanskelig å løse ut eller få heng og lett å løse ut. Men jeg fant ingen plass det var lett å løse ut.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of surface hoar • Within half a meter • Easy to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW above 600 masl • Små, til middels str. Svært lokalt.

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Difficult to trigger • 2 - Medium • Few steep slopes E, SE, S, SW, W above unknown masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter

• Dry slab avalanche • Buried weak layer of surface hoar • Within a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Spontaneous release • 1 - Small • Some steep slopes N, NE, E, SE, S, SW, W, NW above 1000 masl • Små løssnøskred

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl • Per nå skal det trolig store tilleggsbelastninger til for å løses ut, men gammel fokksnø kan potensielt bli mer problematisk ved stor snøpålagring og videre oppbyggende omvandlig fra kaldværet.

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. • Difficult to trigger • 1 - Small • Some steep slopes N, NE, E, SE, S, SW, W, NW above unknown masl

Avalanche Problems

• Loose dry avalanche • Loose snow • Spontaneous release • 1 - Small • Few steep slopes S, SW, W above 500 masl • Økende sannsynlighet utover ettermiddagen.

• 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 • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 500 masl

Avalanche Problems

• Dry slab avalanche • The weak layer collapses easily and clean (easy propagation). A big and identifiable crystal in the weak layer. • Very easy to trigger • 2 - Medium • Few steep slopes SE, S, SW above unknown masl
