Avalanche warning for region Jotunheimen Friday 04.05.2018

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The collapsing weak layer is thin < 3 cm. • Easy to trigger • Possible • 2 - Medium • Many steep slopes N, NE, NW above 0 masl

Avalanche Problems

• Loose dry avalanche • Easy to trigger • Possible • 2 - Medium • Some steep slopes NW above 1300 masl • Dette er lokalt i Ringsbotn og opp til Ringsbreen

Avalanche Problems

• Dry slab avalanche • Poor bonding between crust and overlying snow • Within half a meter • The overlying slab is soft. • Easy to trigger • Possible • 2 - Medium • Some steep slopes N, NE, E, SE, S above 1400 masl • Tirsdagssnøen mott gl. Dekke. Kanskje str. 3 hvis der er mer nysnø enn her i høyden

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The overlying slab is soft. • Spontaneous release • Possible • 2 - Medium • Some steep slopes N, NE, E, SE, S above 1400 masl • Ferskeste fokksnø. Kunne også meldes som ølsalg med nedføyka nysnø

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 • Possible • 2 - Medium • Few steep slopes N, NE, E above 1500 masl • Fokksnøflak på lausere snø oppover Hurrbrean fra ca 1500 moh.

• 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 collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Easy to trigger • Possible • 1 - Small • Few steep slopes N, NE, E, SE, S, SW, W, NW above 1500 masl • Så et tynt flakskred sørvendt i renne under Veslefjelltind som sannsynligvis hadde løsnet på dette laget.

Avalanche Problems

• Dry slab avalanche • Poor bonding between crust and overlying snow • Within half a meter • The overlying slab is soft. • Easy to trigger • Possible • 1 - Small • Some steep slopes S, SW, W above 1600 masl • Kanskje du kan klare og finne enkelte plasser med str. 2

• Loose wet avalanche • Loose snow • Spontaneous release • Possible • 1 - Small • Some steep slopes S, SW, W between 1600 masl and 1000 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Easy to trigger • Unlikely • 2 - Medium • Few steep slopes N, NE, NW above 1300 masl
