Avalanche warning for region Trollheimen Saturday 22.01.2022

Danger level 3 - Considerable avalanche danger

Published:
Large naturally released wet avalanches are likely, also above treeline. Use great caution on recently loaded slopes in the high alpine.

Avalanche problems

Wet snow (slab avalanches)

Avalanches may release spontaneously on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Water pooling in/above snow layers

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 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

Det har kommet mye nysnø i regionen. I høyden er snøoverflaten preget av fokksnø med varierende hardhet. I terreng skjermet for vind og i skogen er det stedvis mye løs snø. Vindutsatte områder er avblåst til bakken eller skare. Det gamle snødekket antas stabilt etter "Gyda" og gjenfrysing, unntatt i de høyestliggende områdene.

Det ble observert flere store og opptil svært store skred i Oppdalsområdet de siste dagene.

Onsdag meldte observatør om kraftig snøfokk nord i Trollheimen. Det ble torsdag formiddag observert 35 cm nysnø ved Oppdal, og 20 cm nysnø i Sunndalen.

Mountain weather

Friday 21. January 2022

10 mm precipitation, up to 18 mm in the most exposed areas. Rain up to 900 m a.s.l during the afternoon. Moderate gale from northwest, changing to breeze from the northwest during the afternoon. -9 °C to -2 °C at 1400 m a.s.l. Cloudy.

Saturday 22. January 2022

1 mm precipitation, up to 8 mm in the most exposed areas. Rain up to 1300 m a.s.l during renoon. Fresh breeze from west, changing to moderate gale from the southwest during the evening. -5 °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

Skredfaren øker i takt med mildværet. I lavlandet ventes naturlig utløste våte skred. Over skoggrensen og opptil ca 1300 moh ventes store våte flakskred i områder som har samlet mye snø de siste dagene.

Over mildværsgrensen vil fokksnø gradvis stabiliseres, men i enkelte heng kan en skiløper fortsatt løse ut store skred.
