Avalanche warning for region Lofoten og Vesterålen Monday 18.12.2017

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • Possible • 3 - Large • Many steep slopes N, NE, E, SE, S, SW, W, NW above 300 masl

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Easy to trigger • Possible • 3 - Large • Some steep slopes N, NE, E, NW above 400 masl

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. • Easy to trigger • Possible • 2 - Medium • Many steep slopes N, NE, E, SE, S, SW, W, NW above 300 masl • Stor utbredelse, men som igår er overliggende lag nok så seige. Men når laget er skjært opp går det relativt lett til brudd med forplantning hele veien.

Avalanche Problems

• Buried weak layer of new snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). A big and identifiable crystal in the weak layer.

• Poor bonding between crust and overlying snow • Within half a meter • The collapsing weak layer is thin < 3 cm.

Svært god futt i svakt lag, men det er et stykke opptil selve flaket og oppleves derfor mer stabilt enn det det nok er.
