Avalanche warning for region Lofoten og Vesterålen Friday 17.12.2021

Danger level 2 - Moderate avalanche danger

Published:
Be careful in areas with fresh wind deposited snow at higher elevations. A few small wet avalanches can still occur at lower elevations.

Avalanche problems

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).

Poor bonding between layers in wind deposited snow

Persistent weak layer (slab avalanches)

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

Buried weak layer of faceted snow near surface

Wet snow (loose snow avalanches)

Avalanches may release spontaneously on a few steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

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)

Thursday 16. December 2021

Snøoverflaten under rundt 500-700 moh har blitt fuktig etter mye regn denne uken. Det er lite snø og det stikker opp steiner flere steder.

I høyden forventer vi harde fokksnøflak etter siste dagers nysnø og kraftig vind.


Under den harde fokksnøen ligger det svake lag av kantkorn. Disse lagene ventes å være borte nå under 500-700 moh på grunn av regn og milde temperaturer de siste dagene, men vil trolig eksistere i høyden.

Mountain weather

Thursday 16. December 2021

10 mm precipitation, up to 16 mm in the most exposed areas. Rain up to 700 m a.s.l during the afternoon. Moderate gale from west, changing to moderate gale from the northwest during the afternoon. -2 °C to 4 °C at 700 m a.s.l. Cloudy.

Friday 17. December 2021

7-10 mm precipitation. Precipitation as rain. Fresh breeze from west, changing to moderate gale from the southwest during the afternoon. -1 °C to 4 °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

Snøskredfaren er mest framtredende i høyden nå. Her har kraftig vind og nysnø dannet flak av fokksnø. Disse kan stedvis være lett å løse ut. Grunnet milde temperaturen også i høyden venter vi at de mange steder har bundet seg godt til eksisterende underlag. Det kan fortsatt være svake lag av kantkorn dypere i snødekket, men disse er nå vanskelig å påvirke.

Under omtrent 700 moh venter vi at snødekket er vått og lite lagdelt. Med unntak av enkelte små våte skred er skredfaren lav her.
