Avalanche warning for region Sør-Troms Thursday 16.12.2021

Danger level 2 - Moderate avalanche danger

Published:
Avoid areas with wind deposited snow at higher elevations. There could be buried layer of facets underneath the wind slabs. A few small wet avalanches can still occur.

Avalanche problems

Wind drifted snow (slab avalanches)

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

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

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

Snøoverflaten under rundt 500 moh har blitt fuktig etter gårsdagens regnvær.
Vinden har preget snøfordelingen over og rundt tregrensen. Gårsdagens nysnø har dannet fokksnøflak i høyden som har lagt seg over eldre, harde fokksnøflak.

Under den harde fokksnøen og ved bakken ligger det svake lag av kantkorn.

Mountain weather

Wednesday 15. December 2021

13 mm precipitation, up to 22 mm in the most exposed areas. Rain up to 500 m a.s.l during the afternoon. Fresh breeze from southeast, changing to fresh breeze from the southwest during the evening. -5 °C to 1 °C at 700 m a.s.l. Cloudy.

Thursday 16. December 2021

16 mm precipitation, up to 30 mm in the most exposed areas. Rain up to 700 m a.s.l during the afternoon. Fresh breeze from southwest, changing to strong breeze from the northwest during the afternoon. -2 °C to 2 °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

I høyden venter vi ytterlige pålagring og dermed fare for å løse ut skred i fokksnøen. Fokksnø ligger over et lag av kantkorn. 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 500-700 moh, der nedbøren kom som regn på onsdag og torsdag, venter vi et vått snødekket. Det kan fortsatt går enkelte våte skred der, men vi venter at skredaktiviteten er mindre enn på onsdag. Det tynne snødekket vil drenere regnet fort. Eldre svake lag vil bli ødelagt av vannet i snøen.
