Avalanche warning for region Salten Thursday 16.12.2021

Danger level 3 - Considerable avalanche danger

Published:
Difficult conditions. Avoid areas with wind deposited snow at higher elevations. Wet avalanches can still occur at lower elevations.

Avalanche problems

Wind drifted snow (slab avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Poor bonding between layers in wind deposited snow

Persistent weak layer (slab avalanches)

Avalanches may release spontaneously on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3). Remote triggering is possible.

Buried weak layer of faceted snow near surface

Wet snow (loose snow avalanches)

Avalanches may release spontaneously 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)

Wednesday 15. December 2021

Kraftig regn de siste dagene har gjennomfuktet snødekket opp til 500-700 moh. I høyden har kraftig vind og nysnø dannet store fokksnøflak i lesider og forsenkinger. Under den siste nysnøen ligge eldre, harde fokksnøflak.

Under den harde fokksnøen ligger det svake lag av kantkorn. Opp til 500 moh forventer vi at disse lagene har stabilisert seg på grunn av vann i snøen.

Mountain weather

Wednesday 15. December 2021

35 mm precipitation, up to 50 mm in the most exposed areas. Rain up to 700 m a.s.l during renoon. Moderate gale from south, changing to moderate gale from the west during renoon. -5 °C to 0 °C at 1100 m a.s.l. Cloudy.

Thursday 16. December 2021

20 mm precipitation, up to 40 mm in the most exposed areas. Rain up to 700 m a.s.l during the afternoon. Moderate gale from west. -4 °C to 0 °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

Snøskredfaren ventes å forbli betydelig. I høyden ventes det store mengder nysnø kombinert med svært kraftig vind. Ustabile fokksnøflak vil fortsatt være til stede og bare vokse i størrelsen.
Det er usikkert hvor ustabilt kantkornlaget er. Drønn og skytende sprekker er tydelige tegn på at kantkornet ikke klarer å bære den nye lasten. Se på alle fjellsider med sammenhengende snødekke og stor pålagring som mistenkelig til det motsatte er bevist.

Under rundt 700 moh, der nedbøren kommer som regn ventes det avtagende skredaktivitet. Det tynne snødekket vil være gjennomfuktet og drenere regnet fort. Eldre svake lag vil bli ødelagt av vannet i snøen. Enkelte våte skred kan fortsatt forekomme.
