Avalanche warning for region Hallingdal Monday 17.01.2022

Danger level 2 - Moderate avalanche danger

Published:
Be careful in areas with windslabs. A persistent weak layer of facets may be triggered, especially where the snow cover is thin and above 1300 m.

Avalanche problems

Wind drifted 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).

Poor bonding between layers in wind deposited snow

Persistent weak layer (slab avalanches)

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

Buried weak layer of faceted snow above a crust

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)

Sunday 16. January 2022

Det har kommet noe nysnø i kombinasjon med kraftig vind de siste dagene. Under siste fokksnø er det gamle snødekket hardt og stabilt opp til ca. 1400 moh, etter at Gyda herjet.
Det er generelt lite snø i regionen, med mye oppstikkende stein og vegetasjon. Det er kun skiføre i innblåste østvendte leformasjoner over 1200 moh.

Forventes at Gyda har ødelagt eller lagt et hardt lokk over gamle vedvarende svake lag i snødekket opp til ca. 1400 moh. Over 1400 moh kan det finnes aktive vedvarende svake lag.

Lørdag ble det meldt om skytende sprekker og drønn ned i dypt kantkornlag på ca.1400 moh.

Mountain weather

Sunday 16. January 2022

8 mm precipitation, up to 15 mm in the most exposed areas. Rain up to 700 m a.s.l Sunday night. Moderate gale from west, changing to storm from the northwest during the evening. -9 °C to -3 °C at 1400 m a.s.l. Cloudy.

Monday 17. January 2022

2-4 mm precipitation. Rain up to 500 m a.s.l during the evening. Gale from northwest, changing to strong breeze from the northwest during renoon. -11 °C to -3 °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

Meste av snødekket er kraftig vindpåvirket og det forventes at det er lite løs snø igjen å flytte på. Det forventes at det stort sett er vanskelig å løse ut skred, men i beskytta lommer og søkk kan det finnes mykere flak som kan være lett å løse ut. Det kan også være vedvarende svake lag på de høyeste toppene som kan gi større skred.
