Avalanche warning for region Indre Troms Monday 02.01.2023

Danger level 3 - Considerable avalanche danger

Published:
Conditions are dangerous. Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Be aware of a persistant weak layer buried by windslabs. With all the new snow sunday it can be hard to get danger signs from these layers, but if they first collapse, avalanches can become large.

Avalanche problems

Persistent weak layer (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). Remote triggering is possible.

Buried weak layer of faceted snow near surface

Wind drifted snow (slab avalanches)

You can easily 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 1. January 2023

Søndag var det snøfall i regionen. Før dette kom siste store snøfall julaften med 30-60 cm snø, mest i Tamokdalen. Denne julesnøen har i ettertid blitt påvirket av vind, og snøoverflata veksler mellom harde og myke flak. Under skoggrensa er snøen ubunden og kan stedvis være fuktet.

Dypere i snødekket finnes lag av kantkorn og rim som ble danna i november og første del av desember. Disse har ugunstige eigenskaper og har den siste tida gitt faretegn som kraftige drønn og skytende sprekker.

Mountain weather

Sunday 1. January 2023

10 mm precipitation, up to 15 mm in the most exposed areas. Rain up to 200 m a.s.l Sunday night. Breeze from west, changing to moderate gale from the west during renoon. -11 °C to -4 °C at 1100 m a.s.l. Cloudy.

Monday 2. January 2023

8-12 mm precipitation. Rain up to 200 m a.s.l during renoon. Strong breeze from west, changing to breeze from the northwest during the afternoon. -13 °C to -4 °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

Roligere værforhold, men de svake lagene i snødekket vedvarer. Søndagens snøfall gjør at det nå vil være enda vanskeligere å få faretegn fra de svake lagene dypere i snødekket, men hvis de først kollapser kan skred bli store. Grunnet lite observasjoner gjennom nyttårshelgen er de svake lagenes egenskaper og utvikling ganske usikker.

Den ferske fokksnøen, som hovedsakelig har blåst inn i østvendte leheng, vil gradvis stabilisere seg, men det vil fortsatt være mulig å løse ut skred også på disse flakene.
