Avalanche warning for region Sør-Troms Saturday 24.03.2018

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • 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 • Possible • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 200 masl

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Easy to trigger • Possible • 2 - Medium • Some steep slopes N, S, SW, W, NW above 200 masl • Vind i løpet av søndag fra øst har blåst snø inn i leheng.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • Possible • 2 - Medium • NE between 600 masl and 0 masl

Avalanche Problems

• 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). A big and identifiable crystal in the weak layer. • Easy to trigger • Likely • 2 - Medium • W, NW above 900 masl • 5 cm ned i snølaget

• Wet slab avalanche • Buried weak layer of faceted snow beneath a crust • Within a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Easy to trigger • Likely • 2 - Medium • SW, W above 900 masl • 30 cm ned i snølaget

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • A big and identifiable crystal in the weak layer. • Easy to trigger • Possible • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 200 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of faceted snow near surface • Within half a meter • The overlying slab is soft. A big and identifiable crystal in the weak layer. • Possible • 3 - Large • Many steep slopes S, SW above 1100 masl • Kantkornlag er 10 cm tykt. Ligger oppå meltfreeze faset lag. Laget over kantkornlag er myk fokksnø. Fire fingre.

Ser at det er store variasjoner av snømengde fra jeg starter å gå til jeg kommer høyere opp. Graver på ca 400moh, og opp til hit kan jeg trykke stav dypt ned før den stopper. Dette går ikke like lett lengre opp.

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The collapsing weak layer is thin < 3 cm. The overlying slab is soft. • Difficult to trigger • Unlikely • 2 - Medium • Few steep slopes N, NE, E, SE, S, SW, W, NW above 500 masl • Ligger på ca 15-20 cm nede i snøpakken. Overliggende lag mykt men bundet

• 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 collapsing weak layer is thin < 3 cm. The overlying slab is soft. A big and identifiable crystal in the weak layer. • Spontaneous release • Likely • 2 - Medium • Many steep slopes N, NE, E, SE, S, SW, W, NW below 500 masl

Avalanche Problems

• Dry slab avalanche • Buried weak layer of new snow • Within half a meter • The overlying slab is soft. • Difficult to trigger • Possible • 2 - Medium • NE, E, SE above 700 masl

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • A big and identifiable crystal in the weak layer. • Difficult to trigger • Possible • 3 - Large • Few steep slopes NE, E, SE above 600 masl

Avalanche Problems

• Loose snow • Possible • 2 - Medium • Few steep slopes E between 700 masl and 0 masl • Finner svakt lag, sprø haggel @40cm. Dette er under et flak med nysnø. Dette gir ikke utslag på ECT
