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.

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 store nedbørsmengder fører til svært store ustabile nysnøflak i leområder over mildværsgrensa. Under mildværsgrensa er det fare for store våte skred. Stigende mildværsgrense utover dagen.
