Avalanche warning for region Tromsø Friday 04.02.2022

Danger level 3 - Considerable avalanche danger

Published:
The avalanche hazard increases as the wind picks up. It’s possible to trigger avalanches in wind slabs, which may be on top of persistent weak layers. Deep persistent layers exist but are very hard to trigger.

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.

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 kan det ha 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 desse godt beskytta av hard overliggande snø dei fleste stadar.

Torsdag blei eit lite skred løyst ut på Djeveltanna.

Mountain weather

Thursday 3. February 2022

No precipitation. Fresh breeze from southeast, changing to strong breeze from the southeast during the evening. -22 °C to -8 °C at 700 m a.s.l. Partly cloudy.

Friday 4. February 2022

Little to no precipitation. Gale from southeast, changing to moderate gale from the southeast during the evening. -14 °C to -9 °C at 700 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

Oppdatert 04.02.22 kl 09:30: 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.Vedvarande svake lag som ligg djupare i snødekket vil truleg framleis vere vanskelege å påverke.
