Avalanche warning for region Hallingdal Thursday 13.04.2023

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable conditions. Be aware of unstable wind slabs in the alpine. There can be a persistent weak layer high in the snow cover.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Buried weak layer of new snow

Wet snow (loose snow avalanches)

Avalanches may release spontaneously on a few steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

Loose snow

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.

Det er flere kantkornlag i snødekket.

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 kan være lett å løse ut skred i ferske fokksnøflak som følge av ny nedbør og vind. Mest utsatt er heng mot nord og vestlige retninger. Vær oppmerksom på at ferske flak også kan ligge over svakt lag av kantkorn høyt i snødekket og gi ekstra ustabilitet.

I lavlandet kan det være lett å løse ut løssnøskred i bratte heng der snøen er myk og våt.
