Avalanche warning for region Jotunheimen Friday 04.03.2022

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 2 - Medium • Few steep slopes E, SE above 1000 masl • Den nyeste snøen er fortsatt ikke helt bundet til det eldre snødekke. Det vil nok skje i løpet av noen dager, men siden det er ganske kaldt, vil det ta litt tid.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Difficult to trigger • 1 - Small • Some steep slopes NE, E, SE above 1100 masl • Generelt stabli lite påvirkelig fokksnø.

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Over one meter • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 3 - Large • Some steep slopes NE, E, SE above 1200 masl • Svært lite sannsynlig med skred på bakken enda.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Few steep slopes NE, E, SE, S above unknown masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • 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. • Difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above unknown masl

Avalanche Problems

• 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 • 2 - Medium • Few steep slopes N, NE, E, SE, S above 900 masl
