Avalanche problems

Wind drifted snow (slab avalanches)

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

Poor bonding between layers in wind deposited snow

Wet snow (slab avalanches)

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

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)

Thursday 2. January 2020

Torsdag er det forbigåande mildvær opp til ca. 1000 moh, samt nedbør og sterk vind. Ettersom det blir kaldare vil snødekket fryse under mildværsgrensa. Over mildværsgrensa vil snøoverflata sannsynlegvis vere vindpåverka, og fokksnø vil finnast stadig lavare ettersom mildværsgrensa synk.

Det har vore eit kantkornlag høgt i snødekket, men etter fleire mildvær er det usikkert om dette framleis eksisterer. Eit kantkornlag som har vore mellom skare og fokksnø lenger ned i snødekket er truleg intakt.

Mountain weather

Thursday 2. January 2020

18-20 mm precipitation. Fresh breeze from southeast, changing to moderate gale from the southwest during the afternoon. -2 °C to 3 °C at 700 m a.s.l. Cloudy.

Friday 3. January 2020

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

Temperaturen blir lavare og det ventast færre våte skred. Fokksnøflak vil dannast stadig lavare og finnast i fleire himmelretningar sidan vinden dreiar.
