Avalanche warning for region Hardanger Thursday 05.12.2019

Danger level 3 - Considerable avalanche danger

Published:
There are fresh wind deposited snow at high altitude. At lower altitude the snowpack is still wet and unstable. Avoid potential release areas and runout areas for avalanches.

Avalanche problems

Wind drifted snow (slab avalanches)

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

Poor bonding between layers in wind deposited snow

Wet snow (slab avalanches)

You can easily trigger avalanches on a few 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

Snøoverflaten er preget av fuktighet høyt til fjells. Over 1400 moh er snøoverflaten kald og tørr. Det er generelt lite snø i regionen. Sammenhengende skiføre finnes over ca 800 moh og det er betydelig mindre snø enn normalt. Vind fra V-NV før mildværet har flyttet snø over i østvendte heng.

Det finnes kantkorn ved bakken, men det er begrenset med snø over. Usikkert i hvor stor grad dette laget er påvirket av mildværet.

Mountain weather

Wednesday 4. December 2019

6 mm precipitation, up to 15 mm in the most exposed areas. Fresh breeze from southwest, changing to moderate gale from the southwest during the afternoon. -3 °C to 0 °C at 1400 m a.s.l. Partly cloudy.

Thursday 5. December 2019

30 mm precipitation, up to 60 mm in the most exposed areas. Gale from southwest, changing to strong breeze from the southwest during the afternoon. -4 °C to 0 °C at 1400 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

I de høyeste fjellområdene vil det i leområder samle seg fersk fokksnø. Det vil være lett å løse ut skred før fersk snø binder seg til underlaget. Skred kan også gå naturlig. Størrelsen vil være avhengig av snømengde. Stedvis kommer det mye snø, og det kan forventes enkelte store skred.
Mildvær og regn gir fortsatt våte skredproblem i lavere høyde. Disse kan løsne naturlig og helt nede ved bakken. Problemet begrenses i takt med tilgjengelig snømengde.
