You can easily trigger avalanches on many steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Buried weak layer of new snow

Wet snow (slab avalanches)

Below you can see a description of the current snow cover information and current weather forecast in the mountains. If your observations deviate greatly from what is described here, the warning will not necessarily apply either. Always make your own judgments or stay away from avalanche terrain.

Snow cover (in Norwegian)

Tuesday 10. December 2019

Fersk fokksnø av ulik hardheit og mengde preger snødekket i høgda. Djupare i snødekket er det fuktig og delvis smelteformer av ulik hardheit, og det kan være aktivt kantkorn i dei høgaste områda på fjellet. Lågare i fjellet er snødekket meir varmepåvirka.

Det er svakt lag av kantkorn nede ved bakken i høgda, det er så langt ikkje observasjonar på at det er aktivt igjen.

Observasjoner viser stor forskjell i fordeling av snø i høgda etter hard vind den siste tida.

Mountain weather

Tuesday 10. December 2019

20 mm precipitation, up to 40 mm in the most exposed areas. Breeze from northwest, changing to moderate gale from the southeast during the afternoon. -10 °C to 2 °C at 1100 m a.s.l. Cloudy.

Wednesday 11. December 2019

25 mm precipitation, up to 35 mm in the most exposed areas. Strong breeze from southwest. -3 °C to 1 °C at 1100 m a.s.l. Cloudy.

Advice

The bulletin is a planning tool and may differ from the actual situation. Always make your own evaluation. To be 100 % avalanche safe, avoid all avalanche terrain.

Avalanche risk assessment

Vind og tildels store nedbørmengder som snø i fjellet vil gi fersk fokksnø i mange heng.
Svakt lag av kantkorn kan ved stor pålagring gi store skred som går til bakken. Under mildværsgrensa er det forhold for våte skred.
