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)

Friday 18. March 2022

Snøoverflaten er de fleste steder gjenfrosset smelteformer.


En lengre periode med mildvær har gjort det gamle snødekket til en stabil pakke med smelteformer til ca 1000 moh.

Høyt til fjells er det fortsatt lagdelt tørr snø.

Det er lag av delvis utviklet kantkorn høyt i snødekket. Laget regnes ikke som et problem nå.

Det er også vedvarende svake lag av kantkorn rundt skarelag lenger ned i snødekket.

Mountain weather

Friday 18. March 2022

15 mm precipitation, up to 20 mm in the most exposed areas. Rain up to 600 m a.s.l during renoon. Strong breeze from south, changing to gale from the southwest during the evening. -5 °C to -1 °C at 1100 m a.s.l. Cloudy.

Saturday 19. March 2022

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

Nedbørsmengder som regn kan føre til naturlig utløste skred.

Våte flakskred ventes over skoggrensen når mildværet fukter fokksnøflakene som ble dannet fredag.

Over mildværsgrensen kan det gå store naturlig utløste tørre flakskred.

I lavlandet kan det gå enkelte naturlig utløste våte løssnøskred.
