Avalanche warning for region Indre Sogn Tuesday 06.02.2024

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within half a meter • The overlying slab is soft. • Difficult to trigger • 2 - Medium • Few steep slopes E

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. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Few steep slopes E, SE, S above 900 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl • Virker ikke som om dette forløpig er et problem, men det er nok gradient til en oppbyggende prosess.

Avalanche Problems

• Loose dry avalanche • Poor bonding between layers in wind deposited 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. • Easy to trigger • 1 - Small • Some steep slopes above unknown masl

• Wet slab avalanche • Poor bonding between layers in wind deposited snow • Within a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • below unknown masl • Innad i den fuktige fokksnøen lengre ned i snødekket

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Few steep slopes E, SE above 900 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Few steep slopes NE, E, SE above 900 masl • Usikker på hvor langt den oppbyggende prosessen har kommet der en har mer fokksnø over. Men det snødekket er tynt, finner en kant under øverste skarelag. Setter høydenivå til over 900, men mistenker at skaren her er tjukk og derfor svært vanskelig å påvirke. Er nok mer aktuelt lenger opp der en har tynnere, mindre bærende skare

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • The weak layer collapses easily and clean (easy propagation). A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Some steep slopes NE, E, SE above 1000 masl • Lett å løse ut der hvor man har ikke eller går gjennom skarelag og snøen er tynt. Eller at man for "step down" med hjelp av fokksnøen. Jeg har ikke gjort observasjoner på vestlige sektor nå i siste, derfør bare østlige sektor markert.

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Some steep slopes N, NE, E, SE above 100 masl • Fokksnøen stabiliserer seg fort hvis mildere temperatur fortsetter. Allerede nå var fokksnøen ganske fint bundet i skarelagen. Tillegg skarelag er ganske ruv/ujevn under fokksnøen.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Spontaneous release • 3 - Large • Some steep slopes N, NE, E, SE, S above 800 masl • Både nedføyka laussnø og sjikt i fokksnøen. Sett naturlege str 2 og 3 i området frå helga og i dag

Avalanche Problems

• Loose dry avalanche • Loose snow • Spontaneous release • 1 - Small • Some steep slopes N, NE, E, SE, S, SW, W, NW below 900 masl • Hvertfall opp til 900moh

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 4 - Very large • Few steep slopes N, NE, E, SE above 1100 masl • Var ikke høyt nok til å se etter dette. Men skal ta en titt på det i morgen i høyden

• 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. • Easy to trigger • 3 - Large • Some steep slopes N, NE, E, SE above 900 masl • Gradvis mer bunden snø over tregrensa.
