Avalanche warning for region Hallingdal Thursday 17.03.2022

Danger level 2 - Moderate avalanche danger

Published:
Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. With high additional load it is possible to trigger persistent weak layers in a few areas.

Avalanche problems

New 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).

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)

Wednesday 16. March 2022

I fjellet er snøoverflaten stort sett vindpåvirket og hard. I skjerma østvendte leformasjoner kan det ligge løsere snø. En del steder er snøoverflaten omdannet til kantkorn, som gir raskt skiføre.

Det har vært observert overflatekantkorn og overflaterim i regionen. Utbredelsen er nok størst i nordvendte heng der sola ikke har tatt tak. Dypere i snødekket finnes det svake lag av kantkorn, men disse ligger stort sett under harde fokksnøflak eller skare.

Mountain weather

Wednesday 16. March 2022

1-4 mm precipitation. Rain up to 1000 m a.s.l during the afternoon. Breeze from south. -13 °C to 0 °C at 1400 m a.s.l. Cloudy.

Thursday 17. March 2022

6-10 mm precipitation. Rain up to 700 m a.s.l Thursday night. Fresh breeze from southeast, changing to breeze from the southwest during the evening. -8 °C to -2 °C at 1400 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

Litt nedbør og en del vind fører til moderat skredfare torsdag. Det kan være lett å løse ut skred der det legger seg fokksnø. Vær obs på at flakene kan ha lagt seg over overflaterim eller overflatekantkorn, i så fall vil flakene være svært lette å løse ut.

I noen få heng kan det være mulig å løse ut skred på svake lag av kantkorn ved stor tilleggsbelastning. Vær obs på at områdene der svake lag finnes sammenfaller med der det er interessant å ferdes på ski.
