Avalanche warning for region Trollheimen Saturday 04.04.2020

Danger level 3 - Considerable avalanche danger

Published:
Difficult conditions. As a skier, avoid lee areas with wind deposited snow. Especially in the tree line where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger there. Natural released storm slabs are still possible.

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

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 3. April 2020

Overflata er preget av mye snø den siste uka med store fokksnøansamlinger i le for vinden. Flere runder med mildvær tidligere i mars, det siste onsdag opp til ca 900 moh har stabilisert snødekket i de laveste områdene. På vindutsatte steder ligger hard skare i overflata.

Det er mye snø i fjellet og store skavler mot Ø.

Kraftig snøvær i regionen torsdag til fredag. I Sunndalen opp til 40 cm nysnø. Bygene har også kommet til Oppdal med 20-40 cm nysnø som er vindpåvirka.

Mountain weather

20 mm precipitation, up to 30 mm in the most exposed areas. Moderate gale from northwest, changing to fresh breeze from the northwest during renoon. -12 °C to -8 °C at 1400 m a.s.l. Cloudy.

Saturday 4. April 2020

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 ventes uendret lørdag. Pågående nedbør gjør at det fortsatt er svært krevende å ferdes trygt i fjellet. Naturlig utløste skred er fortsatt mulig, men mindre vind gir begrenset pålagring. Det er fortsatt mange heng som er ustabile og i noen heng kan skredene bli store. En skiløper vil derfor kunne løse ut skred der det ligger mjuke flak.
