Snow cover (in Norwegian)

Tuesday 18. January 2022

Det har kommet mye nysnø i regionen. I høyden er snøoverflaten preget av fokksnø med varierende hardhet. I terreng skjermet for vind og i skogen er det stedvis mye løs snø. Vindutsatte områder er avblåst til bakken eller skare. Det gamle snødekket antas stabilt etter "Gyda" og gjenfrysing, unntatt i de høyestliggende områdene.

Det ble meldt om opptil 50 cm nysnø og kraftig snøfokk ved Oppdal, og 25 cm nysnø i Sunndalen mandag morgen.

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

Over mildværsgrensen vil mye nysnø og kraftig vind av skiftende retning gi ferske fokksnøflak i leheng. Skred kan løsne naturlig, og i noen heng kan de bli store. I enkelte utsatte heng kan svært store skred forekomme. Synkende nysnøgrense utover dagen.

Natt til onsdag vil regn og mildvær gi fare for naturlig utløste våte skred under mildværsgrensen. Faren for våte skred avtar i takt med synkende temperatur fra onsdag morgen.
