Avalanche warning for region Lofoten og Vesterålen Wednesday 14.03.2018

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 collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • Likely • 2 - Medium • Some steep slopes

• Dry slab avalanche • Buried weak layer of surface hoar • 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. A big and identifiable crystal in the weak layer. • Easy to trigger • Likely • 2 - Medium • Some steep slopes NE, E, SE

A big and identifiable crystal in the weak layer. • Easy to trigger • Likely • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 0 masl • Fokksnø fra i går.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • 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. A big and identifiable crystal in the weak layer. • Spontaneous release

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 collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • Likely • 2 - Medium • Many steep slopes N, NE, SW, W, NW above 300 masl

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • 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. • Easy to trigger • Possible • 2 - Medium • Some steep slopes N, NE, SW, W, NW above 500 masl

Avalanche Problems

• Buried weak layer of new snow • Within half a meter • Likely • 2 - Medium • Many steep slopes N, NE, E, SE, NW above 1100 masl • Nysnøflak sklir av lett. Jo høyere opp man kommer jo hardere blir det øverste laget og desto lengre skytende sprekker. Flaket sklir på nedføyket nysnø/sjiktlag.

A big and identifiable crystal in the weak layer. • Easy to trigger • Likely • 2 - Medium • Some steep slopes N, NE, E, W, NW above 200 masl • Ikke observert, men antatt ut ifra værforhold, snøtransport og tidligere snødekke. Tror dette skal være et defensivt anslag, kan fort skjerpe seg enda et hakk.
