Avalanche warning for region Hallingdal Friday 18.03.2022

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 a few 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)

Thursday 17. 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

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.

Friday 18. March 2022

1-4 mm precipitation. Rain up to 400 m a.s.l during the afternoon. Strong breeze from west, changing to fresh breeze from the southwest during the afternoon. -8 °C to -2 °C at 1400 m a.s.l. Partly 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

Kraftig vind fra vestlig retning kan omfordele snøen som kom torsdag. Det kan være lett å løse ut skred der det ligger fersk 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 dypere i snødekket ved stor tilleggsbelastning. Vær obs på at områder med svake lag sammenfaller med der det er interessant å ferdes på ski.

Små naturlig utløste våte skred kan forekomme i nysnøen dersom sola tar tak.
