Avalanche warning for region Jotunheimen Saturday 07.01.2023

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near the ground • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Very easy to trigger • 2 - Medium • Many steep slopes N, NE, E, SE, S, SW, W, NW between 1300 masl and 800 masl • Rundt tregrensa.

• Dry slab avalanche • Buried weak layer of surface hoar • Within half a meter • 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 • Some steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within 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 • Some steep slopes N, NE, W, NW above 900 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within 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 • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above unknown masl

A big and identifiable crystal in the weak layer. • Very easy to trigger • 2 - Medium • Many steep slopes N, NE, S, SW, W, NW above 900 masl • Såpass svak vind fra øst i skoggrensa at man trolig finner lett bunden nysnø i alle himmelretninger. Men generelt har vi den høyere fraktet og vindpåvirket snøen mot øst me. Ligger i dyner likevel opptil observert høyde.

• 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. • Easy to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 1000 masl • Utpreget løs kant og beger i bunnen av snødekket over alt.

Avalanche Problems

• Buried weak layer of faceted snow near the ground • Within a meter • The weak layer collapses easily and clean (easy propagation). A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • NE, E, SE above 900 masl • Observasjonen fokuserer i hovedsak på østvendt terreng over 900 moh. ved Fv. 53, men fins trolig i flere eksposisjoner og høydeintervaller

• Loose dry avalanche • Loose snow • 2 - Medium • Some steep slopes NE, E, SE • Lite vind på observasjonstidspunktet gav varierende nysnøtjukkelse på 15-25cm. Med venta økende vind og nedbør fra øst og sørøst vil problemet trolig være mest aktuelt i vestlig sektor og trolig bli overlagra med vindåpvirkede snøflak, og kanskje avtagende i østlig sektor.
