Avalanche warning for region Sør-Troms Wednesday 15.12.2021

Danger level 2 - Moderate avalanche danger

Published:
It is easy to trigger avalanches as a result of a rapid temperature rise in combination with precipitation and wind.

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).

Poor bonding between layers in wind deposited 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 (slab avalanches)

Avalanches may release spontaneously on some 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)

Tuesday 14. December 2021

Snøoverflaten under rundt 500 moh har blitt fuktig etter gårsdagens regnvær. Det er generelt lite snø i denne høyden.

Vinden har preget snøfordelingen over og rundt tregrensen. I leområder ligger det harde fokksnøflak.

Det er observert et lag med kantkornet snø under fokksnøen og ved bakken.

Mountain weather

Tuesday 14. December 2021

1-5 mm precipitation. Rain up to 500 m a.s.l during the afternoon. Fresh breeze from southeast, changing to strong breeze from the southeast during the afternoon. -8 °C to 0 °C at 700 m a.s.l. Cloudy.

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.

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

En liten temperaturøkning i kombinasjon med nedbør og vind gjør at skedfaren øker. Det vil legge seg opp ferske fokksnøflak i høyden som vil være mulig å løse ut for en enkelt skiløper. Noen steder kan det også være mulig å påvirke fokksnøflak som ligger over et vedvarende svakt lag av kantkorn. Regn opp til 500 moh. gjør at det også ventes flere naturlig utløste våte løssnøskred. Skredfaren vil være størst der det kommer mest nedbør i form av snø eller regn.
