Avalanche warning for region Sør-Troms Monday 19.12.2022

Danger level 3 - Considerable avalanche danger

Published:
Avoid lee areas where a persistent weak layer can be hidden in the snow pack. Avalanches is triggered most easily where the snow pack is thin, typically close to ridges and on convex formations. Remote triggering is possible.

Avalanche problems

Persistent weak layer (slab avalanches)

You can very easily trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3). Remote triggering is possible.

Buried weak layer of surface hoar

Wind drifted snow (slab avalanches)

You can trigger avalanches on some 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)

Sunday 18. December 2022

Det har vært lite nedbør i helgen, men det er fortsatt mye løs snø tilgjengelig etter stort snøfall forrige uke som kulden og stedvis lite vind har bevart.

I høyden er det vedvarende svake lag i snødekket. Utbredelsen er begrenset til renner, søkk og forsenkinger. Det ble observert drønn i snøen i helgen.

Mountain weather

Sunday 18. December 2022

No precipitation. Breeze from southeast. -16 °C to -5 °C at 700 m a.s.l. Partly cloudy.

Monday 19. December 2022

3-6 mm precipitation. Precipitation as snow. Fresh breeze from northeast, changing to breeze from the southeast during the afternoon. -13 °C to -3 °C at 700 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

Generelt ustabile forhold. I noen heng har det lagt seg opp tjukke fokksnøflak over vedvarende svake lag av overflaterim eller kantkorn. Her kan skredene bli store og stabiliseringen går sakte til tross for rolig vær.

Med nåværende snødekkeoppbygging vil stabiliseringen gå sakte, selv om det var rolig vær i helgen.
