Avalanche warning for region Lofoten og Vesterålen Tuesday 20.12.2022

Danger level 2 - Moderate avalanche danger

Published:
Be aware that there can be pockets with persistent weak layer beneath wind deposited snow. Be careful in these areas, especially in and close to terrain traps.

Avalanche problems

Persistent weak layer (slab avalanches)

You can very easily trigger avalanches on a few steep slopes. Avalanches can get large enough to bury or even kill you (size 2). Remote triggering is possible.

Buried weak layer of surface hoar

Wind drifted snow (slab avalanches)

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

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)

Monday 19. December 2022

Det er mye løs snø tilgjengelig etter større snøfall forrige uke. Det er stor lokal forskjell i mengden. Mest kom rundt Andøya og Hinnøya.
Før dette siste snøfallet var snødekket relativt tynt og det stakk opp mye stein og kratt selv høyt til fjells.

Nysnøen har begravd ustabile lag av kantkorn og rim som hadde stor utbredelse i terreng både over og under skoggrensen før snøfallet. I helgen ble det fortsatt observert skytende sprekker og drønn tilknyttet disse svake lagene.

Mountain weather

Monday 19. December 2022

4-8 mm precipitation. Precipitation as snow. Fresh breeze from north, changing to breeze from the northeast during the afternoon. -10 °C to -1 °C at 700 m a.s.l. Partly cloudy.

Tuesday 20. December 2022

2-4 mm precipitation. Precipitation as snow. Fresh breeze from east, changing to strong breeze from the east during renoon. -13 °C to -2 °C at 700 m a.s.l. Partly 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

Fokksnøflakene som ble dannet før og i løpet av helgen kan fortsatt løses ut der de ligger på et svakt lag av kantkorn eller rim. Flakene blir hardere. Utbredelsen av slike steder og størrelsen til potensielle skred vurderes som avtagende.
Økende vind om ettermiddagen kan danne ferske, tynne fokksnøflak.
