Avalanche warning for region Indre Troms Sunday 01.01.2023

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.

Avalanche problems

Persistent weak layer (slab avalanches)

Avalanches may release spontaneously 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)

Avalanches may release spontaneously 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 31. December 2022

I jula kom det 30-60 cm snø i regionen, mest i Tamokdalen. Snøen har i ettertid blitt påvirket av vind, og snøoverflata veksler mellom harde og myke flak. Under skoggrensa er snøen ubunden.

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

Saturday 31. December 2022

4-8 mm precipitation. Precipitation as snow. Moderate gale from southeast, changing to fresh breeze from the southwest during the evening. -12 °C to -5 °C at 1100 m a.s.l. Cloudy.

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.

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

Vindøkning og nytt snøfall vil føre til stor vindtransport av snø inn i leheng. Enkelte store naturlige skred forventes der de svake lagene i snøen ikke tåler den økte belastningen fra snøfallet. Der det kommer mest snø kan det også gå skred i den ferske fokksnøen.

Unngå skredterreng.
