Avalanche warning for region Jotunheimen Sunday 19.04.2020

Avalanche Problems

• Loose wet avalanche • Loose snow • Spontaneous release • 2 - Medium • Many steep slopes SE, S, SW

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Very difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, W, NW 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. A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Some steep slopes NE, E, SE between 2000 masl and 1200 masl

• 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 collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Some steep slopes NE, E, SE between 2000 masl and 1200 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of surface hoar • Within half a meter • A big and identifiable crystal in the weak layer. • Very easy to trigger • Likely • 3 - Large • SE between 1600 masl and 0 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 1400 masl • Ferskt problem. Ser ikke ut til å være særlig overlastet med fokksnø. Ikke et aktivt problem nå, kanskje bortsett fra i svært bratte heng over terrengfeller.

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • 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 1300 masl

• Loose wet avalanche • Loose snow • Spontaneous release • 2 - Medium • Few steep slopes SE, S, SW below unknown masl • Faren er størst der sola tar mest. Variasjon gjennom dagen
