Avalanche warning for region Helgeland Sunday 20.02.2022

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)

Saturday 19. February 2022

Det var tirsdag til torsdag kraftig vind fra østlig retning som har lagt igjen store flak med fokksnø i leområder mot vest. Snøoverflaten over tregrensen er vindpåvirket, med avblåste partier på utsatte områder.

Det er stedvis observert et svakt lag av begynnende kantkorn over skare. Det er usikkert hvor aktivt dette laget er.

Mountain weather

Saturday 19. February 2022

5 mm precipitation, up to 15 mm in the most exposed areas. Precipitation as snow. Breeze from southwest. -16 °C to -8 °C at 1100 m a.s.l. Cloudy.

Sunday 20. February 2022

4 mm precipitation, up to 10 mm in the most exposed areas. Precipitation as snow. Breeze from southwest, changing to fresh breeze from the southeast during the afternoon. -14 °C to -7 °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 en liten vindøkning utover dagen kan gi pålagring av fersk fokksnø i leheng. Utsatte steder kan det være lett å løse ut skred. Det kan også lokalt finnes steder der fokksnøen fra tidligere i uken fortsatt er ustabil.

Det finnes et vedvarende svakt lag rundt et skarelag fra mildvær i januar, spesielt i indre deler av regionen. Observasjoner tyder på at laget generelt tåler stor tilleggsbelastning, men hvis det først løsner skred på laget kan de bli store.
