Avalanche warning for region Vest-Telemark Friday 06.12.2019

Danger level 2 - Moderate avalanche danger

Published:
Be careful in and close to terrain traps and on steep slopes until the fresh snow has stabilized. Be aware that persistent weak layers can be hidden in the snow pack.

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).

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 5. December 2019

Mildværet i starten av uka fuktet øvre del av snøpakka helt opp til 800-1000 moh, og i lavereliggende områder ble snøen gjennomfuktet. Temperaturen har nå sunket noe, og det er ventet at snødekket vil fryse til i høyereliggende områder. Torsdagens kombinasjon av sterk vind og snø har dannet ferske fokksnøflak hovedsaklig i helninger mellom nord og øst.

Det er tidligere observert kantkorn og begerkrystaller i bunnen av snødekket vest i regionen. I østlige deler er det ingen rapporter på vedvarende svake lag.

Mountain weather

Thursday 5. December 2019

6 mm precipitation, up to 15 mm in the most exposed areas. Gale from southwest, changing to strong breeze from the southwest during the afternoon. -2 °C to 2 °C at 1100 m a.s.l. Cloudy.

Friday 6. December 2019

3-6 mm precipitation. Fresh breeze from west, changing to breeze from the northwest during the afternoon. -2 °C to 2 °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

Roligere vindforhold vil gi fokksnøen fra torsdag tid til å stabilisere seg noe, men første del av dagen kan det fortsatt danne seg noen nysnøflak i østlige heng. Det kan være mulig å løse ut skred i kantkornlag ved bakken, men det antas at det da skal stor tilleggsbelastning til.
