Avalanche warning for region Vest-Telemark Thursday 30.12.2021

Danger level 2 - Moderate avalanche danger

Published:
The avalanche danger rises with temperature, naturally released wet avalanches likely. Unstable wind slabs may rest on buried surface hoar in the alpine.

Avalanche problems

Wet snow (loose snow 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)

Loose snow

Persistent weak layer (slab avalanches)

You can easily trigger avalanches 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) 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)

Wednesday 29. December 2021

Det er svært lite snø i regionen. Snøoverflaten preges av vekslende skare med mye oppstikkende stein og vegetasjon. I formasjoner som samler snø høyt til fjells, kan det finnes sammenhengende snødekke med noe fokksnø i overflaten.

Kaldt klart vær har dannet overflaterim på hard snøoverflate en del steder. Det er også observert kantkorn mot bakken sør i regionen mandag - og kantkorn under skare noe ned i snødekket høyt til fjells i Rauland onsdag.

Natt til tirsdag kom opp i 10-15 cm nysnø sør i regionen, noen få cm i nord. Nysnøen har lagt seg oppå overflaterimet.

Mountain weather

Wednesday 29. December 2021

Little to no precipitation. Calm/light breeze from southeast. -13 °C to -5 °C at 1100 m a.s.l. Cloudy.

Thursday 30. December 2021

4-8 mm precipitation. Rain up to 1300 m a.s.l during the evening. Strong breeze from southwest. -6 °C to 2 °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

Skredfaren øker med overgang til varmegrader helt opp mot høyfjellet. Det er fare for naturlig utløste våte løssnøskred i bratt terreng. I høyden er det lett å løse ut små fokksnøflak som kan ligge på nedføyket overflaterim. Stigende mildværsgrense utover dagen.
