Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on many 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 5. March 2020

Sørøsten har tatt hardt i fjellet. Det er nå hard fokksnø de fleste steder. Enkelte vindutsatte steder er avblåst. Det er mye snø i hele regionen. I godt beskyttede formasjoner og i skogen finnes det løsere snø.

Det finnes svake lag av kantkorn nede i snødekket, men disse ligger dypt og er lite sannsynlig å påvirke.

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

Vestaværet gir påfyll av snø og det dannes ustabile fokksnøflak i leformasjoner. Det ventes store lokale forskjeller i snømengde. Skredfaren vil oppleves som veldig varierende etter hvor man er i regionen. Følg med på hvor snøbygene treffer. Skredfaren er økende så lenge det snør og blåser.

En vinddreining gjør at mest utsatt himmelretning skifter i løpet av dagen.

Fokksnøen fra onsdag og torsdag stabiliserer seg og det skal mer til for å påvirke gamle fokksnøflak.
