Avalanche warning for region Trollheimen Monday 23.01.2023

Danger level 3 - Considerable avalanche danger

Published:
Warmer weather and high precipitation will lead to naturally triggered avalanches at lower elevations and large easily triggered slabs at higher elevations.

Avalanche problems

Persistent weak layer (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). Remote triggering is possible.

Buried weak layer of faceted snow near the ground

Wet snow (loose snow avalanches)

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

Loose snow

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).

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 22. January 2023

Snødekket er generelt preget av vind. Det er mindre snø enn vanlig i fjellet. Rygger og fjelltopper er avblåst.

Kantkorn ved bakken finnes mange steder. Det er mest utviklet i indre del av regionen, der snødekket er tynnest. Stedvis gir kantkornlaget fra seg faretegn som drønn og skytende sprekker.
Det finnes skarelag i snøen opp til 700-900 moh som ble dannet rett før nyttår. Kantkorn har vært under utvikling i forbindelse med skarelaget.

Mountain weather

Sunday 22. January 2023

No precipitation. Fresh breeze from southwest, changing to strong breeze from the southwest during the afternoon. -13 °C to -2 °C at 1400 m a.s.l. Clear skies.

Monday 23. January 2023

10 mm precipitation, up to 22 mm in the most exposed areas. Rain up to 1500 m a.s.l during the evening. Fresh breeze from southwest, changing to moderate gale from the southwest during the evening. -6 °C to 0 °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

Nedbør og mildvær svekker snødekket. Under mildværsgrensen vil regnet kunne gi naturlig utløste skred. Skred kan gå naturlig, og det kan ikke utelukkes at enkelte naturlig utløste skred blir store. Det kan også gå naturlig utløste glideskred.
Over mildværsgrensen vil det bygge seg opp mye snø i leheng. Skred vil være lette å løse ut og der det har lagt seg mest snø kan de bli store.

Det er usikkerheter rundt nedbørsmengder. Mindre regn vil gi lavere skredfare.
