Avalanche warning for region Trollheimen Tuesday 28.03.2023

Danger level 2 - Moderate avalanche danger

Published:
Be careful in shaded areas with wind slabs and in sun exposed steep slopes.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Poor bonding between layers in wind deposited snow

New snow (loose snow avalanches)

Avalanches may release spontaneously on some 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 27. March 2023

Natt til mandag kom det opp mot 20 cm nysnø fra nord, med lokale variasjoner. Det ligger noen ferske nysnøflak særlig i leområder mot sør. Det kom mest nysnø og med mest vind i Sunndal og Surnadal, noe mindre i Oppdalsområdet.

Det gamle snødekket består av smelteomvandlet snødekke til ca 700 moh. Over dette er det gradvis tørrere. I høyden er det stort sett fast fokksnø eller hard skare under nysnøen.

Mountain weather

Monday 27. March 2023

2-6 mm precipitation. Precipitation as snow. Breeze from northeast, changing to breeze from the north during the afternoon. -23 °C to -8 °C at 1400 m a.s.l. Partly cloudy.

Tuesday 28. March 2023

0-3 mm precipitation. Precipitation as snow. Calm/light breeze from northwest, changing to fresh breeze from the southeast during the afternoon. -25 °C to -7 °C at 1400 m a.s.l. Clear skies.

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

I høyden kan det være lett å løse ut nysnøflak i gårsdagens flakdannelser. Vær obs dersom vinden blir sterk nok til å flytte snø lokalt. Mest utsatt er ved rygger, skar og topper der vinden tar mest.

Når sola blir sterk utover dagen kan det gå noen skred som løsner av seg selv i nysnøen. Flest små skred er ventet, men noen kan bli middels store. Det ventes flest løssnøskred, men enkelte flakskred kan også løsne av seg selv.
