Snøoverflata er preget av mildvær med hard skare og fokksnø i høyden. Under tregrensa er snødekket fuktig og kompakt.

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

Det gamle snødekket anses som stabilt og skredfare er i stor grad knyttet til den nyeste snøen. Kraftig vind og mye nedbør gir skredproblem med ustabile nysnøflak i leområder over mildværsgrensa. Under mildværsgrensa er det fare for våte skred. Mildværsgrensa vil variere gjennom døgnet.
