Avalanche warning for region Trollheimen Thursday 08.04.2021

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. A big and identifiable crystal in the weak layer. • Very easy to trigger • 2 - Medium • Some steep slopes E, SE, S above 600 masl

• Loose dry avalanche • Loose snow • Spontaneous release • 1 - Small • Some steep slopes N, NE, E, SE, S, SW, W, NW above 0 masl • Antagelig mest sannsynlig i sørlig sektor.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within a meter • The overlying slab is soft. • Easy to trigger • 2 - Medium • Some steep slopes E, SE, S, SW above 1000 masl

• Loose dry avalanche • Loose snow • Spontaneous release • 1 - Small • Some steep slopes E, SE, S above 700 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 2 - Medium • E, SE, S above 700 masl • Ved obs punkt er problemet den nyeste snøen som kom i natt. Høyere opp i terrenget er nysnøen mer bundet og danner flak. Den tykke fokksnøpakken som ble dannet søndag-tirsdag virker å ha stabilisert seg raskt i denne fjellsiden. Fant ikke kantkornproblemet i denne høyden i denne fjellsiden.

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. A big and identifiable crystal in the weak layer. • Easy to trigger • 3 - Large • Some steep slopes NE, E, SE, S above 700 masl

• Loose wet avalanche • Loose snow • Spontaneous release • 2 - Medium • Some steep slopes E, SE, S, SW, W above 600 masl

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Over one meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • N, NE, E, SE, S, SW, W, NW above 1100 masl • Obs på at skred i fokksnøen kan trappe ned på disse lagene.

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Spontaneous release • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 1100 masl • Mulig at fokksnø kan trappe ned til dette. Da kan vi få str 4 skred.
