Avalanche warning for region Jotunheimen Thursday 18.04.2024

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • Very difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 1700 masl • Eldre lag av kantkorn lenger nede i snødekket under hard fokksnø. De er vanskelig å påvirke, men skredene kan bli store.

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • 1 - Small • Some steep slopes N, NE, E, NW above 1600 masl • Kantkorn nær overflaten under stedvis skare/fokksnø

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Few steep slopes NE, E above 1300 masl • Usikker utbredelse. Men skal uansett mye til å løsne skred her nå. Enten høye temperaturer og kraftig oppbløtning, Tid og temp gradient, eller mye ferdk snø over.

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). A big and identifiable crystal in the weak layer. • Easy to trigger • 1 - Small • Few steep slopes N, NE between 1600 masl and 1400 masl • Står mellom lett og løse str 1 få heng eller vanskelig å løse str 2 svært få heng. flaket har stabilisert seg godt. Og det var vanskelig å finne både nok snø, men og sammenhengene nok flak i dag. Derfor lander jeg på lett, str 1, få heng.

• Loose wet avalanche • Loose snow • Spontaneous release • 1 - Small • Few steep slopes SE, S, SW above 1000 masl

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 overlying slab is soft. • Easy to trigger • 2 - Medium • Some steep slopes N, NE, E above 1700 masl
