Avalanche warning for region Indre Fjordane Tuesday 10.04.2018

Avalanche Problems

• Loose wet avalanche • Loose snow • Spontaneous release • Very likely • 3 - Large • Many steep slopes S, SW

• 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. A big and identifiable crystal in the weak layer. • Easy to trigger • Possible • 2 - Medium • Some steep slopes N, NE, NW above 1300 masl

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within a meter • Difficult to trigger • Possible • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl • Vanskelig å generalisere. Påstand om stor tilleggsbelastning skyldes bare at mildværet ikke så ut til å ha utløst noe særlig.

Avalanche Problems

• Wet slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The weak layer collapses easily and clean (easy propagation). The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • Possible • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl • Det vil være lettast å påverke kantkornlaga der det overliggande snødekket er tynt. Der dei ligg djupare, vil det kreve stor tilleggsbelastning, hvis ein klarar å påverke dei. Over mildvêrsgrensa tørre flakskred.

• 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 • Possible • 2 - Medium • Some steep slopes N, NE, W, NW above 1100 masl

• Loose wet avalanche • Loose snow • Spontaneous release • Possible • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW below 1000 masl • Kan også gå våte flakskred pga vannmetta lag i snødekket
