Avalanche warning for region Indre Troms Wednesday 04.01.2023

Danger level 2 - Moderate avalanche danger

Published:
There is a persistent weak layer buried in the snow pack. It can be difficult to get danger signs from the weak layers, but if they collapse avalanches can become large in some slopes. Be careful in areas with wind deposited snow.

Avalanche problems

Persistent weak layer (slab avalanches)

You can 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 faceted snow near surface

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).

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)

Tuesday 3. January 2023

De to første dagene i året har det kommet en del snø, og under skoggrensa er snøen ubunden og løs. I fjellet er det variende hardhet fra svært hard vindpåvirket snø fra i fjor, til noe mykere fokksnøflak fra nyttårsnøen.

Dypere i snødekket finnes lag av kantkorn og rim som ble danna i november og første del av desember. Disse har ugunstige egenskaper og har den siste tida gitt faretegn som kraftige drønn og skytende sprekker. Virker å være mest potent over ca 600moh.

Mountain weather

Tuesday 3. January 2023

2-4 mm precipitation. Precipitation as snow. Calm/light breeze from southwest. -16 °C to -7 °C at 1100 m a.s.l. Partly cloudy.

Wednesday 4. January 2023

No precipitation. Breeze from southeast. -19 °C to -11 °C at 1100 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

Rolig vær, men fortsatt svake lag i snødekket. Siste dagers snøfall gjør at det nå potensielt kan være enda vanskeligere å få faretegn fra svake lag med kantkorn dypere i snødekket, men hvis disse lagene først kollapser kan skred bli store.

Fokksnøflakene vil gradvis stabilisere seg, men med noe lavere temperaturer går det saktere. Utover dagen vil det bli vindøkning fra sørøst, og ferske fokksnøflak kan dannes i nye leheng. Her vil det være lett å løse ut skred.
