Avalanche warning for region Lofoten og Vesterålen Monday 15.02.2021

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Many steep slopes NE, E, SE above 500 masl

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Over one meter • The weak layer collapses easily and clean (easy propagation). 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

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • 1 - Small • Many steep slopes N, NE, E, SE, S, SW, W, NW between 400 masl and 100 masl

• 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 • 2 - Medium • Some steep slopes N, NE, E, SE, S above 600 masl

Avalanche Problems

• Buried weak layer of faceted snow near the ground • Within half a meter • The overlying slab is soft. • 2 - Medium • N, NE, E, SE, S, SW, W, NW above 200 masl • Fra 200 moh oberverte vi at snøen sprakk godt opp rundt skia(men ikke skytende sprekker). Finner et tydelig lag med kantkorn ved bakken. Merker også at det ligger under et lag med skare.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within 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 • Many steep slopes E, SE, S, SW, W above 400 masl • Er store krystall som ligner mer på beger/overflaterim enn klassisk kantkorn. Gir derav rufsete brudd.

Avalanche Problems

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. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • E, SE, S • Kollapser på et lag med tydelige og store kantkorn.

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 easy to trigger • SE, S

Avalanche Problems
