Avalanche warning for region Jotunheimen Sunday 04.02.2018

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). A big and identifiable crystal in the weak layer. • Difficult to trigger • Unlikely • 3 - Large • Many steep slopes N, NE, E, SE, S, SW, W, NW • Skredproblemet ligger over et skarelag som nesten er på bunnen av snødekket. Hvor dypt det ligger varierer veldig avhengig av snødekkets tykkelse. Funnet på alt fra 30 cm til 100 cm dybde.

• 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 • Likely • 2 - Medium • Few steep slopes above 0 masl • Vinden har generelt tatt lite så snøen er i stor grad ubundet i de aller fleste heng.

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 collapsing weak layer is thin < 3 cm. • Difficult to trigger • Unlikely • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 0 masl

• Buried weak layer of new snow

A big and identifiable crystal in the weak layer. • Easy to trigger • Possible • 3 - Large • Many steep slopes N, NE, E, SE, S, SW, W, NW above 900 masl • Utbredt, ligger mellom stor og liten tillggdbelastning.

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The weak layer collapses easily and clean (easy propagation). The collapsing weak layer is thin < 3 cm. • Easy to trigger • Possible • 2 - Medium • Many steep slopes N, NE above 1200 masl • Observert to steder i samme fjellside. Kan være innslag av nedbrutte rimkrystaller.
