Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Lag med nysnø med fokklag oppå

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter

Avalanche Problems

• The overlying slab is soft. • N between 1100 masl and 1000 masl

Avalanche Problems

• Loose dry avalanche • Loose snow • Difficult to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S above 800 masl • Det ligger stedvis mye snø i lesider.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • Unknown • Some steep slopes NE, E, SE, S between 1000 masl and 800 masl • Har ikke vert høgere

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Some steep slopes NE, E, SE, S between 1000 masl and 800 masl • Ikkje vert høgere i terreng

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • Unknown • Some steep slopes NE, E, SE, S between 1000 masl and 800 masl • Har ikke gått høyere i terrenget

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Over one meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 2 - Medium • Some steep slopes NE, E, SE, S between 1100 masl and 800 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Over one meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 2 - Medium • Some steep slopes NE, E, SE, S between 1000 masl and 800 masl • Område: Hele fjellet innenfor oppgitt høgde. Ikkje vært høgare enn ca 1000moh.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Easy to trigger • 2 - Medium • Some steep slopes SE, S, SW above 800 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • Very difficult to trigger • 2 - Medium • Many steep slopes above 900 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. • Easy to trigger • 2 - Medium • NE, E, SE between 1100 masl and 800 masl • Vindtransport mest fra vestavind. Minst snø i sørvendte sider. Store variasjoner i snødybde med oppstikkende terreng på småformasjoner.
