Avalanche warning for region Indre Fjordane Thursday 19.12.2019

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 • 1 - Small • Some steep slopes N, NE, E, NW above 600 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, W, NW above 900 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 2 - Medium • N, NE, E, SE, S, SW, W, NW above 1000 masl • Kantkornlag mellom skarelag virker som det svakeste kantkornskiktet, men har foreløpig bare funnet det avblåste steder (ikke under fokksnø). Utbredning og potensiale blir gjetning.

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within a meter • A big and identifiable crystal in the weak layer. • Very difficult to trigger • Few steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl • Kantkorn ved bakken har vokst og blitt løsere etter mildvær, men generelt ikke respons eller drønn. Virker ikke som realistisk skredutløser nå, så kan kuttes ut.
