Avalanche warning for region Indre Fjordane Tuesday 12.04.2022

Avalanche Problems

• 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. A big and identifiable crystal in the weak layer. • Easy to trigger • 4 - Very large • Few steep slopes NE, E, SE, S, SW above 600 masl • Det svake laget har god bruddforplantningsevne, så enkelte skred kan bli svært store. Større utbredelse av str 2 og 3

• Loose wet avalanche • Loose snow • Spontaneous release • 1 - Small • Some steep slopes E, SE, S, SW, W below 700 masl • Mest utsatt dersom sola kjem fram.
