Avalanche warning for region Jotunheimen Thursday 20.01.2022

Avalanche Problems

• 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 • N, NE, E, SE, S, SW, W, NW above 1000 masl

• 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 • E, SE, S above 1000 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 collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 2 - Medium • NE, E, SE between 1100 masl and 900 masl • Mulig dette laget finnes høyere, men opplevde ikke dette i fokksnøflakene jeg gikk på i høyden. Men disse var også svært vindpåvirket. Fant ikke / gikk ikke inn i de "værste" hengene pga fg og sikt osv. men kan nok finne noe noe høyere der det er mer le. Men disse stedene vil være mer isolert og færre. "Få bratte heng" over tregrensa.

Avalanche Problems

Avalanche Problems

• 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 • 2 - Medium • E • Ikke utslag på ECT i det avrundede kantkornlaget, men samme krystaller og mykere ift laget ved bakken der bruddet oppsto.
