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)

Monday 13. February 2023

Siden fredag er det kommet 40-60 cm med nysnø. Nysnøen har lagt seg over et eldre snødekket som er gjennomfuktet opp til minst 500 moh. Høyt til fjells så kom nedbør fra de siste dagene som sludd eller snø i kombinasjon med kraftig vind. Det har derfor lagt seg opp mye snø i nord- og østvendte leområder.

Observasjoner tyder på at alt kantkorn er smelteomvandlet, men noe kan ha overlevd høyt til fjells over 900 moh.

Mountain weather

Monday 13. February 2023

7 mm precipitation, up to 15 mm in the most exposed areas. Rain up to 1000 m a.s.l during the evening. Strong breeze from west, changing to fresh breeze from the west during the afternoon. -6 °C to -1 °C at 1100 m a.s.l. Cloudy.

Tuesday 14. February 2023

4 mm precipitation, up to 12 mm in the most exposed areas. Rain up to 1100 m a.s.l Tuesday night. Fresh breeze from southwest. -3 °C to 0 °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

Fokksnøflakene i høyden har nå fått tid til å stabilisere seg, så det skal nå stor tilleggsbelastning til for å løse ut skred i fokksnøen.

Natt til tirsdag passerer det en varmfront der nedbør vil komme som regn opp til ca. 1100 moh. Temperaturstigningen i kombinasjon med regn gir en kortvarig svekkelse av snødekket, men ikke nok til at det forventes naturlig utløste skred.
