Avalanche warning for region Vest-Telemark Monday 13.04.2020

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable conditions. A skier or a snow mobile may trigger avalanches in the fresh wind slabs, while persistent weak layers deeper in the snow in general is hard to trigger.

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).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

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

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)

Sunday 12. April 2020

Det er generelt mye snø i høyfjellet. Det finnes fersk fokksnø i østvendte fjellsider. Kuler og rygger mot vest er stedvis avblåst til gamle skarelag. Snøoverflaten har tidligere i uka vært fuktet opp til 1200 moh.

Det er observert svake lag med kantkorn rundt skarelag nede i snødekket og ved bakken. Stedvis ligger disse under solid skare og er derfor vanskelige å påvirke. Andre steder er kantkornet lettere tilgjengelig. Det antas at mildværet tidligere i uka har nøytralisert dette laget opp til omtrent 1200 moh.

Søndag formiddag har Haukeliseter (990moh) V stiv kuling og +1 grad. Det har kommet opp mot 10 cm nysnø i regionen siste døgn.

Mountain weather

Sunday 12. April 2020

2-6 mm precipitation. Moderate gale from west, changing to moderate gale from the northwest during the afternoon. -5 °C to 2 °C at 1100 m a.s.l. Partly cloudy.

Monday 13. April 2020

Little to no precipitation. Moderate gale from northwest, changing to strong breeze from the northwest during the evening. -9 °C to -3 °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

Sterk vind kan gjøre at det fortsatt flyttes noe snø inn i sørøstvendte heng.
Vær oppmerksom på at det finnes kantkornlag dypt nede i snøpakka. Stort sett er disse godt beskyttet av bærende overliggende snø, men vær forsiktig der snødekket er mykt og tynt.
