Avalanche warning for region Trollheimen Sunday 29.12.2019

Danger level 3 - Considerable avalanche danger

Published:
Challenging conditions. Wet snow in lower elevations and risk of avalanche releasing in full depth. Conservative terrain choice is essential on freshly loaded storm slabs in the alpine.

Avalanche problems

Wet 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).

Water pooling in/above snow layers

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few 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)

Saturday 28. December 2019

Snøoverflaten er generelt hard og preget av mildværet før siste helg. Litt nysnø i beskyttede områder. På vindutsatte partier er det fokksnø, snøfritt eller gammel skare er blåst frem. Nysnøgrensen ligger på mellom 200 og 300 moh. Det er omtrent normale snømengder for årstiden.

Kantkornlag er observert i snødekket.

Fredag ble det observert overflaterim som delvis var innblandet i nysnøen. Mulig at det enkelte steder i høyden er dannet flak over.

Mountain weather

Saturday 28. December 2019

5 mm precipitation, up to 10 mm in the most exposed areas. Moderate gale from southwest. -6 °C to 1 °C at 1400 m a.s.l. Cloudy.

Sunday 29. December 2019

10 mm precipitation, up to 20 mm in the most exposed areas. Moderate gale from southwest. -3 °C to 3 °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

Stigende temperatur kan bringe mildværsgrensen opp mot de høyeste fjelltoppene. Faren for våte skred vedvarer. I terreng over mildværsgrensen vil snø og vind legge opp ferske fokksnøflak. Skred som løsner kan påvirke vedvarende svake lag nede i snødekket og gi store skred.
