Avalanche warning for region Sunnmøre Saturday 23.01.2021

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable conditions. A skier or a snow mobile may trigger avalanches in the soft wind slabs, while persistent weak layers 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 or even kill you (size 2).

Poor bonding between layers in wind deposited snow

Persistent weak layer (slab avalanches)

You can trigger avalanches on some 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)

Friday 22. January 2021

Snøoverflata varierer mellom harde og mjuke fokksnøsnøflak. Ryggar og konvekse formasjonar er blåst av. Også under tregrensa kan snøen vere vindpåvirka.

Rim og kantkorn danna tidleg på nyåret dannar mange stader tjukke lag med liten bruddforplantningsevne. Det kan imidlertid vere potente lag i enkelte områder, og meir sannsynleg høgt til fjells.

Mountain weather

Friday 22. January 2021

0-3 mm precipitation. Fresh breeze from southeast, changing to breeze from the southeast during renoon. -10 °C to -3 °C at 1400 m a.s.l. Partly cloudy.

Saturday 23. January 2021

7-10 mm precipitation. Fresh breeze from southwest, changing to strong breeze from the south 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 kan løysast ut skred i leheng med mjuke fokksnøflak danna i vind frå sør og søraust. Disse fokksnøflaka kan ligge skjult under nysnø. Gamle fokksnøflak på vedvarande svake lag i snødekket kan løysast ut, helst der flaka er tynne. Skredfaren kan auke om kvelden med aukande vind.
