Avalanche warning for region Vest-Telemark Monday 30.12.2019

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable avalanche conditions in the alpine. Be careful of recently loaded storm slabs. A persistent weak layer of facets may be triggered, especially where the snow cover is thin.

Avalanche problems

New 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).

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 29. December 2019

Snøoverflaten består stort sett av løs snø under skoggrensa. I og over skoggrensa har vinden tatt og ført til fokksnø av varierende hardhet. Snødekket er ganske jevnt fordelt, men det ligger mest snø i terreng mot V og N over skoggrensa.

Søndag ble det observert nedsnødd rim ved Rauland.
Stedvis kan det ligge kantkorn mot bakken, men utbredelsen er liten.

Søndag kl 13 målte Honnegrasnuten (1340moh) +1 grad og V storm.

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

Nysnøgrensen vil gradvis synke med temperatur. Over mildværsgrensen noe fersk fokksnø som er lett å løse ut i leheng. Økende omfang med høyde. Fokksnø vil sannsynligvis feste seg godt til underlaget i takt med at det fryser til. Vær oppmerksom på svake lag der snødekket er tynt/mykt.
