Avalanche warning for region Lofoten og Vesterålen Friday 20.03.2020

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within a meter • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 2 - Medium • Some steep slopes NE, E, SE, S, SW above 600 masl • Dette er et observert problem, men lite relevant nå. Fokksnøflak.

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Very easy to trigger • 2 - Medium • Some steep slopes NE, E, SE, S, SW above 0 masl • Antatt problem, basert på observasjon av nysnømengde og økende vind. Nysnøflak. Er det her som gjelder.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Difficult to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW above 300 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half 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 0 masl • Kantkort observert både @40cm og @80 cm. Disse bryter ikke lett og glatt, og krever middels/hard belastning for å utløses.

Avalanche Problems

• 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 • 3 - Large • Some steep slopes NE, E, SE above 400 masl • Har kun vært i Ø sålangt. Jeg finner laget både på tynn og tykk snøpakke - avstand varierer i terrenget.
