Avalanche warning for region Helgeland Sunday 20.03.2022

Danger level 2 - Moderate avalanche danger

Published:
The situation is 2-sided. Wet avalances can be triggered on steep terrain where the snowpack is wet. Large wind slabs formed on Saturday can easily be triggered, but are expected to gain strength quickly.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches 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

Wet snow (loose snow avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Loose snow

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.

Lørdag er det kraftig mildvær og store mengder nedbør som regn høyt til fjells.

Over 1200-1400 moh kommer nedbøren som snø.

Det er tidligere observert flere lag med kantkorn i snødekket. Hva som er status på disse etter det kraftige mildværet er noe usikkert.

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

Skredfaren er raskt avtagende og situasjonen to-delt.

Under mildværsgrensen vil snødekket være vått og det kan være lett å løse ut våte skred i bratt terreng.

I høyfjellet har det i løpet av lørdagen kommet svært store mengder nysnø med vind. Disse fokksnøflakene ventes å stabilisere seg raskt på grunn av milde temperaturer og at de ble herjet godt med på lørdagen. Men store skred kan løses ut enkelte steder.

Hvordan dype vedvarende svake lag respondere på regnet er usikkert. Det kan ikke utelukkes at det går enkelte svært store skred søndag.
