Avalanche warning for region Indre Fjordane Tuesday 12.02.2019

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. • Easy to trigger • Possible • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl

• Dry slab avalanche • Buried weak layer of surface hoar • 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 • Possible • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl

• Loose wet avalanche • Loose snow • Spontaneous release • Likely • 2 - Medium • Many steep slopes N, NE, E, SE, S, SW, W, NW below 800 masl • Våte laussnøskred vil gå høgare opp etterkvart som temperaturen stig og det blir nedbør som regn høgare til fjells

Avalanche Problems

• 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, NE, E, SE, S above 600 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Within half a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • Unlikely • 3 - Large • Many steep slopes N, NE, E, SE, S, SW, W, NW above 700 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 overlying slab is soft. A big and identifiable crystal in the weak layer. • Spontaneous release • 3 - Large • Some steep slopes N, NE, E, SE, S, NW above 500 masl • Det har komt mye snø de siste dagene og kraftig vind, først fra NV, senere dreid over mot Ø-SØ. Lett utløsbare, myke flak i flere himmelretninger. Mengden snø tilsier nok at skredene i den ferske fokksnøen etterhvert kan nå str. 3.

• Loose wet avalanche • Loose snow • Spontaneous release • 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 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 • 2 - Medium • Some steep slopes NE, E, SE, S above 500 masl • Myke nysnøflak går til brudd ved isolering, tydelig flakdanning fra ca 500moh, lett bundet nysnø.

• Dry slab avalanche • Buried weak layer of faceted snow above a crust • Within a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • Difficult to trigger • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • The weak layer collapses easily and clean (easy propagation). The overlying slab is soft. • Easy to trigger • Possible • 2 - Medium • Some steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl

• Dry slab avalanche • Buried weak layer of surface hoar • 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 • Possible • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl • Leformasjonar bak kantar og ryggar der rimlaget frå tirsdag/onsdag ikkje vart øydelagt før nysnø og pålagring ved vindtransport.
