Avalanche warning for region Indre Fjordane Friday 24.03.2023

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • 2 - Medium • Few steep slopes N, NE, E, NW above 900 masl • Fokksnøen har fått stabilisert seg, men kan nok løysast ut ved stor tilleggsbelastning enkelte stader. Begrensa str. Viser liten evne til bruddforplantning.

• Loose wet avalanche • Loose snow • Spontaneous release • 1 - Small • Some steep slopes SE, S, SW, W above 800 masl • Soloppvarming kan gi skredaktivitet i siste nysnøen

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • Very difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl • Kan fortsatt finnast restar av kantkornlaget rundt skarelag nede i snødekket. Generelt vanskeleg å påvirke, men kan være muleg på stader med tynt snødekke.

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 • 3 - Large • Some steep slopes N, NE, NW above 1000 masl

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Some steep slopes N, NE, E, NW above 1100 masl

Avalanche Problems

• Wet slab avalanche • Poor bonding between crust and overlying snow • Within a meter • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above unknown masl • Merket tydelig lagdeling i nysnøen mot gammel skare.

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Difficult to trigger • 2 - Medium • Some steep slopes NE, E, SE, S above 1000 masl • Fokksnø som hard overliggende lag på skare.
