Avalanche warning for region Indre Troms Friday 04.02.2022

Danger level 3 - Considerable avalanche danger

Published:
The avalanche hazard increase as the wind picks up. Avalanches can occur on wind slabs or on persistent weak layers. The shallowest persistent weak layer is easiest to trigger, while the deepest can give very big avalanches.

Avalanche problems

Wind drifted snow (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).

Buried weak layer of new snow

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.

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a large truck or destroy several houses (size 4).

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)

Friday 4. February 2022

Det skal vere sterk vind frå søraust, som vil påverke snøoverflata. Den vekslar mellom skare, fokksnø av varierande hardheit og ubunden snø, alt etter kvar vinden har, og kjem til, å ta.

Sidan det har vore så kaldt den siste tida har det utvikla seg kantkorn høgt i snødekket, mellom anna rundt skara frå siste mildvær (23. januar). Det finnast også eldre kantkornlag lenger ned i snødekket, men dei er vanskelegare å påverke.

Mountain weather

Thursday 3. February 2022

Little to no precipitation. Fresh breeze from southeast, changing to gale from the southeast during the evening. -25 °C to -13 °C at 1100 m a.s.l. Partly cloudy.

Friday 4. February 2022

3-6 mm precipitation. Precipitation as snow. Storm from southeast, changing to moderate gale from the southeast during the afternoon. -20 °C to -15 °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

Skredfara aukar i samband med vindauke. Det kan gå skred der snø blir lasta inn i leheng. Den vindtransporterte snøen kan legge seg over vedvarande svake lag, som gjer at skred kan bli større enn om slike lag var fråverande. Det er usikkert om vekta av nyinnlasta snø er stor nok til å påverke dei djupare vedvarande svake laga, men om det er det kan det gå svært store skred.
