Avalanche warning for region Salten Friday 17.12.2021

Danger level 3 - Considerable avalanche danger

Published:
Natural avalanches could release at higher elevations and reach 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 some 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)

Thursday 16. 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 all vann i snøen.

Mountain weather

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.

Friday 17. December 2021

20 mm precipitation, up to 25 mm in the most exposed areas. Rain up to 1400 m a.s.l during the afternoon. Strong breeze from southwest, changing to moderate gale from the west during the evening. -4 °C to 1 °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 forbli uendret i høyden. Her fortsetter nysnø og kraftig vind med å danne ustabile flak. Flakene kan bli tykke. Utover dagen ventes regnværet til å nå toppen av de fleste fjellene. Da øker faren for naturlig utløste skred i den ferske fokksnøen over 700 moh.

Under 500-700 moh venter vi at snødekket er vått og lite lagdelt. Her venter vi avtagende snøskredfare. Men vær obs på at store skred som løsner høyere opp til fjells kan nå langt ned i dalen.
