Avalanche warning for region Jotunheimen Thursday 10.02.2022

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. • Easy to trigger • 3 - Large • Many steep slopes N, NE, E, SE, S above 900 masl • Etter SV til NV vind og snøbyger.

• 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, E, SE, S above 1000 masl

A big and identifiable crystal in the weak layer. • 2 - Medium • Some steep slopes NE, E, SE above 1000 masl • Vurdert for Tyin-Årdal. Skredproblem finnes sikkert lavere også. Lett og glatt brudd på LBT, men fikk også ECTN Q3

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl

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 • Many steep slopes NE, E, SE, S above 1000 masl • Får også brudd i de to siste fokksnølagene. Det ferske er mest potent mens det eldre sitter litt bedre. Høyere opp over skoggrensa er det sannsynlig at flakene er hardere og skredene kan bli større, men utbredelsen er mindre.
