Avalanche warning for region Hallingdal Wednesday 23.02.2022

Danger level 3 - Considerable avalanche danger

Published:
The danger increases when the wind picks up. Avoid areas with wind deposited snow, typically behind ridges, ribs and in gullies.
A persistent weak layer of facets may be triggered, especially where the snow cover is thin.

Avalanche problems

Wind drifted snow (slab avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

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)

Tuesday 22. February 2022

Snøoverflaten består i hovedsak av vindtransportert snø med ulik hardhet, med løs snø i skogen og i godt skjerma østvendt terreng. Det er mest snø i østvendt terreng, og mindre snø i vindutsatte og vestvendte områder. Regionen har generelt mindre snø enn normalt øst i regionen.

Det finnes vedvarende svake lag i snødekket fra ca. 1200 moh og høyere. De vurderes som generelt vanskelig å påvirke. Det meldes sporadisk om drønn i områder med tynt snødekke.

Mountain weather

Tuesday 22. February 2022

3-6 mm precipitation. Precipitation as snow. Breeze from southwest. -17 °C to -7 °C at 1400 m a.s.l. Partly cloudy.

Wednesday 23. February 2022

10 mm precipitation, up to 30 mm in the most exposed areas. Rain up to 600 m a.s.l during the afternoon. Moderate gale from southwest. -8 °C to -1 °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 sørvest og nysnø vil føre til fersk fokksnø i leheng som er lett å løse ut. Lengst vest i regionen hvor det kommer mest snø vil det også være fare for naturlig utløste skred når været står på som værst.

Stedvis finnes det vedvarende svake lag i snødekket som gjør situasjonen utfordrende. Eks. vil det være fare for at man enkelte steder kan fjernutløste store skred.
