Avalanche warning for region Trollheimen Friday 24.02.2023

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • The overlying slab is soft. • Difficult to trigger • 2 - Medium • NE, E, SE, S above 1100 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • 3 - Large • Some steep slopes NE, E, SE, S, SW above 700 masl • Svake lag i nysnøen/fokksnøen som kommer, eller i det svake laget under skaren, øverst i snødekket, når det kommer mer snø oppå.

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • The collapsing weak layer is thin < 3 cm. 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 1100 masl and 500 masl • Fant kantkornet snø under skare (antagelig samme lag som er observert i Oppdal) Dette laget lå dypt i dette punktet. I områder der snødekket er tynnere kan det være lettere å løse ut.

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • 2 - Medium • Some steep slopes N, NE, E, NW above 900 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • 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. • Very difficult to trigger • 1 - Small • Few steep slopes SE, S between 1000 masl and 900 masl • Liten forplantningsevne - krever stor tilleggsbelastning.

Avalanche Problems

• Loose wet avalanche • Loose snow • Spontaneous release • 1 - Small • Some steep slopes W between 800 masl and 700 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Easy to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW above 1000 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • 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. • Easy to trigger • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW between 1100 masl and 800 masl • Det er gode forhold for danning av kantkorn. Der skaren er til stede er kantkorndanning i gang.

Det er der det ligger flak på skare. Over 1050 finner jeg ikke drønn og finner heller ikke skaren utbredt, med unntak av på toppen av snødekket. I skoggrense
