Avalanche warning for region Indre Troms Sunday 11.04.2021

Avalanche Problems

• Dry slab avalanche • Poor bonding between crust and overlying snow • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S between 800 masl and 400 masl

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

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 4 - Very large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl • Gammelt vedvarende svakt kantkornlag kan gi svært store skred, fare for fjernutløsing

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • 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, SE, S, SW, W, NW above 500 masl • finner avrundede kantkorn over skare i dette området. Det viser at det kan være områder med kantkorn lavere enn 800moh som beskrevet i varselet. Dette laget kan være dannet etter sist mildværsperiode med noen dager med kaldt klart vær. Utbredelsen er noe usikker.

• Dry slab avalanche • Buried weak layer of new snow • Within a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 3 - Large • N, NE, E, SE, S above 500 masl • tidvis kraftig snøfokk og kraftige snøbyger fører til dannelse av svake lag i fokksnøen
