Avalanche warning for region Jotunheimen Thursday 27.04.2023

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within 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. • Difficult to trigger • 3 - Large • Some steep slopes N, NE, NW between 1500 masl and 1000 masl • Kan være mulig å løse ut i områder der snødekket er tynt.

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within a meter • A big and identifiable crystal in the weak layer. • Very difficult to trigger • 3 - Large • Some steep slopes N, NE, SE, S, SW, NW above 1000 masl • Funnet i nordvendte heng mellom 1000 og 1500 moh og sørvendte heng mellom 1600 og 2200 moh.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • 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 • 2 - Medium • Few steep slopes E, SE, S, SW, W above 1400 masl

• 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 • 1 - Small • Some steep slopes E, SE, S, SW, W above 1400 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. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Few steep slopes E, SE above 900 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. • Easy to trigger • 2 - Medium • Some steep slopes NE, E, SE, S, SW above 1300 masl • Kan finnes i nevnte himmelretninger og skjermede formasjoner forøvrig

Avalanche Problems

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 1600 masl • Samme lag som er observert i Styggehøbreaskardet (SV og N) . Kantkorn ca 45 cm nede i snødekket. Her i heng vendt mot øst. Funnet i 25 grader bratt heng. Ser ut for at det svake laget finnes nesten alle steder der snødekket ikke er gjennomfuktet.
