Avalanche warning for region Jotunheimen Monday 07.02.2022

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • Difficult to trigger • 1 - Small • SW, W

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • The collapsing weak layer is thin < 3 cm. • Difficult to trigger • 3 - Large • NE, E, SE, S above 900 masl • Det svake laget låg djupt der me grov, men vil naturleg vera lettare å påvirka der det ligg mindre snø

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 • Some steep slopes E above 1000 masl • Kantkorn under skarelag vanskelig å påvirke. Nyføket snø over 2 cm nysnø er lettere å løse ut, ingen propagering på vår test men kan være et større problem andre plasser

A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Some steep slopes NE, E, SE, S between 1000 masl and unknown masl • Ble oppmerksom på dette laget ved spadeprøve som ble tatt pga drønn i snøen

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW between 1000 masl and unknown masl • Vi grov i sørvendt heng.

• 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. • Easy to trigger • 2 - Medium • Many steep slopes E, SE, S above 1000 masl • Verre jo høyere man kommer inn pga mer vindtransport i høyden.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 2 - Medium • Some steep slopes NE, E, SE between 1400 masl and 1000 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • NE, E, SE • Snøen samler seg i enkelt flak og på utsatte steder kan det bygge seg opp store mengder snø. Mange steder er fjellet helt avblåst, rett og slett for mye vind for at det legger seg fonner på alle lesider.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 2 - Medium • Some steep slopes NE, E, SE above 1000 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 • Many steep slopes N, NE, E, SE, S between 1100 masl and unknown masl • Nedføyka nysnø (2 cm) som går lett i brot, med laust pakka lag over. Vil truleg stabilisere seg i løp av ein dag eller to.

A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Some steep slopes N, NE, E, SE above 900 masl • Snudde på 1100moh. I dette området var det delvis avblåst så potensiell skredstørrelse middels. Større heng vil kunne løses ut lengre opp.
