Avalanche warning for region Vest-Telemark Tuesday 20.12.2022

Danger level 2 - Moderate avalanche danger

Published:
Use caution in steep terrain with wind deposited snow, it may rest on weak layers of facets og buried surface hoar. Small natural wet avalanches can occur.

Avalanche problems

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.

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)

Monday 19. December 2022

De siste dagene er det observert 20-30 cm nysnø vest i regionen, mindre nysnø lenger øst.
Det er fremdeles generelt lite snø i terrenget. Der vinden har fått tak kan det finnes lommer med vindpåvirket snø.

Snøprofiler har vist at det finnes kantkorn og nedsnødd rim i snødekket. Observerte drønn i løpet av sist uke har sannsynligvis sitt opphav i vedvarende svake lag.

Mountain weather

Monday 19. December 2022

10 mm precipitation, up to 20 mm in the most exposed areas. Precipitation as rain. Fresh breeze from southeast. -6 °C to 0 °C at 1100 m a.s.l. Cloudy.

Tuesday 20. December 2022

3-6 mm precipitation. Precipitation as rain. Fresh breeze from southwest, changing to breeze from the south during the afternoon. -3 °C to 1 °C at 1100 m a.s.l. Partly 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 leheng med fersk fokksnø, og der fokksnø ligger over svakt lag av rim eller kantkornet snø, vil det være lett å løse ut skred. Det er ikke store snømengder i terrenget, så eventuelle skred blir trolig ikke større enn middels store (sr.2).

Det ventes kortvarig temperaturstigning utover dagen. Under mildværsgrensen kan det forekomme enkelte våte løssnøskred som løsner av seg selv.

Små skred kan få store konsekvenser om du blir ført ut i områder med lite snø og oppstikkende stein.
