Avalanche warning for region Helgeland Wednesday 23.02.2022

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable conditions. A skier or a snow mobile may trigger avalanches in the fresh wind slabs, while persistent weak layers deeper in the snow in general is hard to trigger.

Avalanche problems

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).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

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 22. February 2022

I løpet av helgen kom det 10-20 cm snø. Vindøkning mandag har trolig omfordelt noe av nysnøen, men en del steder vil det fortsatt ligge løsere snø, for eksempel i skogen. Eldre snødekke har et skarelag øverst fra mildvær i januar.

Det finnes et svakt lag av kantkorn over skaren. Stabilitetstest fra Vefsn 20. feb viser at laget har evne til bruddforplantning. Det er ikke observert faretegn knyttet til dette siden starten av februar. Observasjoner viser at laget ligger under fokksnø og generelt er vanskelig å påvirke.

Mandag formiddag var det frisk bris på Varntresk målestasjon.

Mountain weather

Tuesday 22. February 2022

No precipitation. Breeze from southeast, changing to strong breeze from the southeast during the evening. -20 °C to -11 °C at 1100 m a.s.l. Partly cloudy.

Wednesday 23. February 2022

6 mm precipitation, up to 12 mm in the most exposed areas. Rain up to 100 m a.s.l during the afternoon. Strong breeze from southeast, changing to gale from the south during the evening. -14 °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

Nysnø og kraftig vind fører til at det dannes nye ustabile fokksnøflak. Det kan være lett å løse ut skred i fokksnøen.

Det finnes et vedvarende svakt lag rundt et skarelag fra mildvær i januar. Det skal generelt stor tilleggsbelastning til for å påvirke laget. Hvis det først løsner skred på laget kan de bli store.
