Locally unstable conditions. A skier or a snow mobile may trigger avalanches in the fresh wind slabs, while persistent weak layers deeper in the snow in general is hard to trigger.

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).

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)

Wednesday 18. December 2019

Snøoverflata er stort sett vindpåverka, men det finst laussnø i skjerma terrengformasjonar. Sterk vind tidlegare i vinter har laga fokksnøflak i leområder i fjellet. På ryggar og toppar er det stort sett avblåst.

Det finst vedvarande svake lag av kantkorn og rim i snødekket og kantkorn ved bakken.

Tysdag vart det observert overflaterim.

Mountain weather

Wednesday 18. December 2019

Little to no precipitation. Fresh breeze from west. -13 °C to -8 °C at 1800 m a.s.l. Partly cloudy.

Thursday 19. December 2019

5 mm precipitation, up to 10 mm in the most exposed areas. Moderate gale from south, changing to fresh breeze from the south during the evening. -11 °C to -6 °C at 1800 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

Vindauke og endring av vindretning saman med nedbør vil føre til pålagring av fersk fokksnø i leområder. Det vart i går observert overflaterim. Ferske fokksnøflak kan i somme områder legge seg på rimlag.
Det finst vedvarande svake lag både ved bakke og høgare i snødekket som det er mogeleg å løyse ut skred på.
