Avalanche warning for region Vest-Telemark Thursday 04.03.2021

Danger level 2 - Moderate avalanche danger

Published:
Be careful on steep slopes with soft and wet snow, a skier can trigger avalanches here, or they can release when the temperature increases. At high altitudes, a persistent layer of facets are buried in the snowpack in isolated areas that may give big avalanches.

Avalanche problems

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of faceted snow beneath a crust

Wet snow (loose snow 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)

Loose snow

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 3. March 2021

Over 1300 moh ligg det litt finkorna snø i overflata, elles består snøoverflata stort sett av skare. Under 1000 moh er snødekket gjennomfukta.

I høgfjellet over ca. 1200 moh finst det framleis vedvarande svakt lag med kantkorn i snødekket.

Tysdag vart det observert eit vått flakskred i Setesdal.

Onsdag formiddag er det minus 9,3 grader C og svak vind frå nord på Hovden i Setesdal.

Mountain weather

Wednesday 3. March 2021

No precipitation. Breeze from northwest, changing to fresh breeze from the northwest during the afternoon. -6 °C to 2 °C at 1100 m a.s.l. Partly cloudy.

Thursday 4. March 2021

No precipitation. Breeze from north. -12 °C to -5 °C at 1100 m a.s.l. Clear skies.

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 høgfjellet kan det vere mogeleg å løyse ut skred på vedvarande svakt lag av kantkorn, men stort sett er overliggande snø hard og bærande og det skal mykje til for å påverke desse laga.
I låglandet der snødekket er smelteomvandla er det stort sett stabile forhold. Låge temperaturar fører til gjenfrysing av våt snøoverflate og stabilisering.

Soloppvarming kan føre til små våte laussnøskred i bratte solvendte sider.
