Avalanche warning for region Hallingdal Sunday 16.01.2022

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 some 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.

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)

Saturday 15. January 2022

Etter det kraftige mildværet torsdag, har nå snødekket fryst til igjen og består av skare.
Det er generelt lite snø i regionen. Fortsatt oppstikkende stein og vegetasjon.

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 er det fare for aktive vedvarende svake lag.

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

Mountain weather

Saturday 15. January 2022

Little to no precipitation. Breeze from southwest, changing to fresh breeze from the southwest during the evening. -10 °C to -3 °C at 1400 m a.s.l. Cloudy.

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.

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 vil legge seg opp noen ferske fokksnøflak i leområder der det kommer nysnø pga sterk vind. Ferske fokksnøflak kan være lett å løse ut. Mest nysnø er ventet vest i regionen, og skredfaren vil derfor være størst der. Det gamle snødekket er hardt og stabilt opp til ca. 1400 moh. På de høyeste toppene er det mulig å løse ut større skred på dypere vedvarende svake lag med kantkorn.
