Avalanche warning for region Jotunheimen Thursday 16.01.2020

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • 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 • Some steep slopes S, SW, W above 1400 masl • Skredproblemet virker ikke særlig aktivt, ikke veldig lett å påvirke og forplantet seg ikke.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Over one meter • The collapsing weak layer is thin < 3 cm. • Very difficult to trigger • 2 - Medium • NW

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • 2 - Medium • Many steep slopes N, NE, E, NW • Lettere å løse ut i 40° og oppover.

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 overlying slab is soft. A big and identifiable crystal in the weak layer. • Very easy to trigger • 2 - Medium • NW • Nedføyket lag av sprøhagl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • 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. • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, NW between 1500 masl and 1300 masl • Kan være lett å løse ut i bratte helninger men bindingene mellom lagene fører til at det sitter godt i mindre bratt terreng under 35 grader.
