Avalanche warning for region Sør-Troms Thursday 07.04.2022

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 • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 400 masl • Størrelsen og tykkelsen på flaket avgjør skred størrelsen. Flest str 2 og enkelte str 3 er sannsynlig.

A big and identifiable crystal in the weak layer. • Easy to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 500 masl • kantkorn over skare finner vi i dag i mange heng i alle eksposisjoner. Bruddforplantningsevne og stabilitet varierer noe, men testene viser at det stort sett er lett å løse ut skred i noen til mange bratte heng.

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 SE, S, SW, W above unknown masl • Svakt lag av DF. Forventes å stabilisere raskt grunnet landet som DF og gunstige temperaturer.

A big and identifiable crystal in the weak layer. • Easy to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 400 masl • Varierer i forhold til hvor lett det er å løse ut, avhenger av egenskapene til flaket.

The overlying slab is soft. • Easy to trigger • 1 - Small • Some steep slopes S, SW, W above 400 masl • Fersk innblåst snø. Bryter lett og glatt, men forventes å stabilisere seg raskt. Svakt lag av DF og gunstige temperaturer for stabilisering.

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • The collapsing weak layer is thin < 3 cm. 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 400 masl • Siste dagers vind har gjort flakene hardere og således vanskeligere å påvirke dette svake laget. Derimot mer spenning i snødekke og skredene kan bli større.
