Avalanche warning for region Jotunheimen Saturday 22.01.2022

Danger level 3 - Considerable avalanche danger

Published:
A skier or a snow mobile may trigger avalanches in wind slabs. Pay extra attention around the treeline. A persistent weak layer deeper in the snow in general is hard to trigger.

Avalanche problems

Wind drifted snow (slab avalanches)

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

Poor bonding between layers in wind deposited 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)

Friday 21. January 2022

Over skoggrensa finnes det store fokksnøflak i øst- og sørvendte leområder. Vindutsatte plasser er avblåst og regionen er preget av lite snø for årstiden. Det ligger relativt mye vindtransportert snø rundt skoggrensa. Under siste fokksnø er det gamle snødekket hardt og stabilt opp til ca. 1200-1300 moh, etter at Gyda herjet.

Under siste periodes fokksnø finnes aktive vedvarende svake lag av kantkorn. Observerte drønn og nylig skredaktivitet stammer mest sannsynlig fra vedvarende svake lag.

Torsdag ble det observert et naturlig utløst str. 2 skred i østvendt terreng i Leirdalen.
Ved Tyinkrysset ble det torsdag observert et naturlig utløst str. 2 skred i østvendt terreng.

Mountain weather

Friday 21. January 2022

1 mm precipitation, up to 6 mm in the most exposed areas. Rain up to 1000 m a.s.l during the afternoon. Moderate gale from northwest, changing to fresh breeze from the west during the afternoon. -12 °C to -4 °C at 1800 m a.s.l. Cloudy.

Saturday 22. January 2022

Little to no precipitation. Strong breeze from west, changing to moderate gale from the west during the evening. -7 °C to -2 °C at 1800 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 blir gradvis varmere og det forventes en gradvis stabilisering av fokksnø i leområder i høyfjellet. Under mildværsgrensa, spesielt i nærheten av skoggrensa, kan flakene bli lettere å påvirke.
I enkelte leområder over 1200 moh er det fare for at skred kan løsne på dype vedvarende svake lag ved stor tilleggsbelastning eller svekkelse i mildværet.
