Avalanche warning for region Jotunheimen Saturday 20.02.2021

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The weak layer collapses easily and clean (easy propagation). • Easy to trigger • 2 - Medium • Some steep slopes NE, E, SE

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • 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 • 3 - Large • Some steep slopes

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • The weak layer collapses easily and clean (easy propagation). The overlying slab is soft. A big and identifiable crystal in the weak layer.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • N, NE, E, SE, S, SW, W, NW above unknown masl • Nedsnødd kantkornet snø, varierende hvor dypt den ligger. Foreløpig er det overliggende laget ganske mykt. Hvis det kommer en kuldeperiode vil det kunne herdes og flakene som kommer vil kunne bli enda større og hardere.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 2 - Medium • Some steep slopes N, W, NW above 1500 masl

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • 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 • 2 - Medium • Some steep slopes N, W, NW above 1500 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 • 1 - Small • Some steep slopes N, NE, NW above 1200 masl • Ser ut som det er mest flakdannelse i nordlig sektor. Mjuke flak og liten respons ved testing.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of surface hoar • 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 • 2 - Medium • Some steep slopes N, NE, SW, W, NW above 1000 masl • Gjør seg gjeldene der vinden har flytta snø

Avalanche Problems

• Dry slab avalanche • 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. • Easy to trigger • 2 - Medium • Many steep slopes SE, S between 1700 masl and 1500 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 2 - Medium • Many steep slopes N, NE, NW between 1800 masl and 1300 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The weak layer collapses easily and clean (easy propagation). The overlying slab is soft. A big and identifiable crystal in the weak layer. • Very easy to trigger • 2 - Medium • Some steep slopes N, SW, W, NW above 1000 masl • Mykere flak enda, men skredproblemet vil trolig øke i omfang når snøen binder seg bedre flere steder.
