Avalanche warning for region Indre Fjordane Wednesday 14.02.2018

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, W, NW above 600 masl

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. • Difficult to trigger • Possible • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl • Regner med at dette laget ligger langt ned i snødekket i mange områder.

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within half a meter • Easy to trigger • Likely • 2 - Medium • N, NE, W, NW above 700 masl

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, W, NW above 700 masl • Den ferskeste og minst stabile fokksnøen ligger i nord. Eldre fokksnø (2-3 dager++) ser ut til å sitte godt.

• 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 • Unlikely • 3 - Large • Many steep slopes N, NE, E, SE, S, SW, W, NW above 800 masl • Kantkorn er tilstede, men ligger de aller fleste steder godt beskyttet under tykke, bærende lag av fokksnø. Lettest å løse ut ved tynt snødekke.

Avalanche Problems

• Dry slab avalanche • Poor bonding between layers in wind deposited snow • Within a meter • Difficult to trigger • Possible • 3 - Large • Some steep slopes N, NE, E, SE, S, SW, W, NW above 700 masl

• Dry slab avalanche • Buried weak layer of faceted snow beneath a crust • Over one meter • Difficult to trigger • Unlikely • 4 - Very large • Few steep slopes 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 overlying slab is soft. • Easy to trigger • Possible • 2 - Medium • Some steep slopes N, NE, E, W, NW 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. The overlying slab is soft. • Difficult to trigger • Unlikely • 3 - Large • Few steep slopes N, NE, E, SE, S, SW, W, NW above 500 masl • Finst svakt vedvarande lag enkelte plassar. Kan truleg påvirkast der det overliggande snødekket er tynt.

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 • Possible • 2 - Medium • N, NE, SW, W, NW above 600 masl • Mjuke flak etter kraftig vind frå austleg retning. Siste snøen, kanskje frå i går, bryter lett og glatt. Sannsynlegvis berre nokre få cm nysnø. Den vindpakka snøen frå nokre dagar tilbake er godt stabilisert.
