Avalanche warning for region Hallingdal Thursday 28.12.2023

Avalanche Problems

• Loose dry avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 1 - Small • Some steep slopes E, S, SW, W between 1500 masl and 1200 masl • Små pga lite binding i utløst lag.

• Loose dry avalanche • Poor bonding between layers in wind deposited snow • Within a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • 1 - Small • Some steep slopes S, SW, W between 1500 masl and 1200 masl • Mulig noe større forplanting mulig, selv om test ikke gav dette. Noe større volumer mulig. Så Mulig størrelse kn være mellom 1 og 2.

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. • Difficult to trigger • 2 - Medium • Few steep slopes NE, E, SE above 1000 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • Difficult to trigger • 2 - Medium • Some steep slopes NE, E, SE, S above 1800 masl

• Dry slab avalanche • Poor bonding between crust and overlying snow • Within a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Very difficult to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW between unknown masl and unknown masl • Sikkert i prinsippet alle retninger, men ser vanskelig for meg at mulig å utløse.
