Avalanche warning for region Trollheimen Tuesday 11.04.2023

Danger level 1 - Low avalanche danger

Published:
Generally stabile conditions. Be aware of isolated storm slabs in the Dovrefjell area where we expect some new snow. Some places wind deposited snow can cover a persistent weak layer. Primarily in northern aspects.

Avalanche problems

Persistent weak layer (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1) Remote triggering is possible.

Buried weak layer of faceted snow near surface

Wet snow (loose snow avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

Loose 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)

Monday 10. April 2023

Snødekket varierer mye med høyde og himmelretning. Solen har nå tatt godt i mange heng og snødekket er omdannet høyt til fjells i sørsider.
I nordsider og slakere terreng i fjellet er snødekket tørt, og består av fokksnøflak av varierende hardhet. Noen steder er det avblåst til gammel skare.

Klart og kaldt vær i hele april har gitt kantkorndanning i overflaten. Det finnes også kantkorn dypt i snødekket under hard og bærende fokksnø, som ikke påvirker skredfaren for øyeblikket.

Mountain weather

Monday 10. April 2023

1-4 mm precipitation. Rain up to 800 m a.s.l during the afternoon. Fresh breeze from southeast, changing to gale from the southeast during the afternoon. -6 °C to 0 °C at 1400 m a.s.l. Cloudy.

Tuesday 11. April 2023

0 mm precipitation, up to 7 mm in the most exposed areas. Rain up to 1000 m a.s.l. Moderate gale from southeast, changing to fresh breeze from the southeast during the evening. -4 °C to 2 °C at 1400 m a.s.l. Partly 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

Sør i regionen ved Dovrefjell der det kommer nysnø, kan fokksnøflak legge seg på rim eller kantkorn i overflaten. Her kan små flak være lette og løse ut. Selv om eventuelle skred ventes å bli små må faretegn som drønn og skytende sprekker tas på alvor.

Der overflata er våt kan en skiløper løse ut som våte løssnøskred.

Ved høye temperaturer om våren øker faren for glideskred og skavlbrudd. Vær forsiktig ved skavler og under glidesprekker.
