Avalanche warning for region Jotunheimen Sunday 13.01.2019

Avalanche Problems

• Dry slab avalanche • Poor bonding between crust and overlying 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. • Easy to trigger • Possible • 2 - Medium • NE, E, SE between 1500 masl and 900 masl • Skredproblemet vil være fremtredende i områder hvor mildværet har dannet skare og det er fersk fokksnø med forplantning over. Dvs. Over eller i skoggrensa og oppover til dit miødværet dannet skaren. I Østlig sektor.

Avalanche Problems

• Buried weak layer of new snow • Within half a meter

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Difficult to trigger • Possible • 1 - Small • Some steep slopes SW above 1300 masl

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. • Easy to trigger • Possible • 2 - Medium • Some steep slopes E, SE, S

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • Possible • 2 - Medium • Some steep slopes E, SE, S, SW, W between unknown masl and 0 masl

Avalanche Problems

• Buried weak layer of new snow • Within a meter

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. • Very easy to trigger • Likely • 1 - Small • NE, E, SE between 1600 masl and 1300 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. • Difficult to trigger • Possible • 2 - Medium • Some steep slopes NE, E, SE, S above 1100 masl • I tillegg til CT og ECT tester har vi gjennomført varianter av rutsj blokker i relevant terreng. Flakene glir ut ved hopp eller gjentatte hopp med ski på beina.

Avalanche Problems
