Avalanche warning for region Vest-Telemark Friday 25.01.2019

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • Very difficult to trigger • 1 - Small • E, SE, S above 800 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within half a meter • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 1 - Small • Few steep slopes N, NE, E, SE, S, SW, W, NW above 1000 masl

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • Difficult to trigger • 1 - Small • Few steep slopes E, SE, S above 1100 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The overlying slab is soft. • Difficult to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl • Litt variert i hvilke heng snøen har samlet seg, så jeg tar med alle himmelretninger.

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • Possible • 1 - Small

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The overlying slab is soft. • Very difficult to trigger • 1 - Small • Few steep slopes E, SE, S above 800 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The overlying slab is soft. • Difficult to trigger • 2 - Medium • Few steep slopes E, SE, S above 700 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • Very difficult to trigger • Unlikely • 1 - Small • Few steep slopes E, SE, S • Vi fant vel egentlig ikke noe ordentlig svakt lag, men det er hardhetsforskjeller i fokksnøen.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within half a meter • Very difficult to trigger • Unlikely • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW above 0 masl • Kankornlag ved bakken vil fortsette å utvikle seg så lenge det er kuldegrader og relativt tynt snødekke. Men det er tykke skarelag over som gjør det vanskelig å utløse skred på dette laget

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • Difficult to trigger • Possible • 1 - Small • N, NE, E, SE, S, SW, W, NW above 0 masl • Det er et ca 3 cm tykt kantkornlag under skare i snødekket. Dette laget kan være tynnere andre steder i snødekket slik at det kan finnes steder hvor man kan løse ut skred på dette laget

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • Difficult to trigger • Possible • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW above 0 masl • Jeg observerte ikke dårlig binding i fokksnøen, men det kan det være andre steder i regionen
