Avalanche warning for region Lofoten og Vesterålen Thursday 23.03.2023

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. • Easy to trigger • 1 - Small • Few steep slopes N, NE, NW above 300 masl • Det varierer mye fra tykt (vanskelig å løse ut selv i nordvendt) til tynt snødekket (svært lett å løse). Stabiliseringen i nordvendt, der det flekkvis ligger små, tynne fokksnøflak på grunn av lokale vindeffekten, går saaaaaakte (her er det kaldt!). Begrenset utbredelse i nord, men likefullt tilstede flekkvis.

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. • Easy to trigger • 1 - Small • Some steep slopes E, SE, S, SW, W above 300 masl • Dette er den ferskeste fokksnøen fra i natt og morgentimene i dag. Fokksnøen stabiliseres raskt. Vinden har løyet.

• Loose dry avalanche • Loose snow • Spontaneous release • 1 - Small • Some steep slopes S, SW above 0 masl • Gjelder for solutløst svært bratt terreng. En kald vind frem til nå har hatt en avkjølende effekt på snødekket.

Avalanche Problems

• Loose dry avalanche • Loose snow • Spontaneous release • 2 - Medium • Few steep slopes SE, S, SW above 0 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. • Very difficult to trigger • 2 - Medium • Few steep slopes NE, E, SE, S, SW above unknown masl

• Loose wet avalanche • Loose snow • Spontaneous release • 2 - Medium • Some steep slopes E, SE, S, SW, W • Solutløste skred.

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 overlying slab is soft. A big and identifiable crystal in the weak layer. • Very easy to trigger • 3 - Large • Some steep slopes E, SE, S, SW, W above 200 masl • Vil sol kunne medføre naturlig utløste skred?
