Avalanche warning for region Vest-Telemark Sunday 01.03.2020

Danger level 3 - Considerable avalanche danger

Published:
Avoid lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger there.

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)

Saturday 29. 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

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.

Sunday 1. March 2020

12 mm precipitation, up to 18 mm in the most exposed areas. Fresh breeze from southeast. -6 °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

Nedbør og vind gjer at det også vert meir pålagring av fokksnø i leområder. Fokksnøen frå i går treng tid på å stabilisere seg. Det vil framleis vere mogeleg å løyse ut skred i denne. 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.
