Avalanche warning for region Vest-Telemark Saturday 29.02.2020

Danger level 3 - Considerable avalanche danger

Published:
The danger increases when the wind picks up. Avoid areas with wind deposited snow, typically behind ridges, ribs and in gullies.

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).

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)

Friday 28. February 2020

Det ligg mjuk vindpåverka snø på overflata. I austvendte leområder har det blitt lasta inn mykje fokksnø.

I nokre områder finst det framleis mykje laussnø i overflata

Ryggar og vindutsatte områder er stadvis avblåst ned til gammal skare.

Gammalt snødekke vert vurdert som stabilt.

Mykje vind og snø i vinter gjer at mange skavlar har blitt store.

Det finst kantkorn i samband med skarelag i snødekket.

Fredag vert det fleire stader observert kraftig snøfokk i høgda.

Mountain weather

Friday 28. February 2020

1-3 mm precipitation. Breeze from southwest, changing to fresh breeze from the west during the afternoon. -12 °C to -4 °C at 1100 m a.s.l. Partly cloudy.

Saturday 29. February 2020

15 mm precipitation, up to 25 mm in the most exposed areas. Fresh breeze from east, changing to moderate gale from the east during renoon. -8 °C to -4 °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

Nedbør og vind gjer at det vert danna fersk fokksnø i leområder. Det er størst sjangs for naturleg utløysing av skred medan pålagringa pågår. Observasjonar viser også at det kan vere mogleg å påverke svake lag av kantkorn i snødekket. Viss desse laga går til brot kan det medføre stor brotforplanting i snødekket.
