Avalanche warning for region Vest-Telemark Wednesday 11.01.2023

Danger level 3 - Considerable avalanche danger

Published:
Demanding avalanche conditions due to a persistent weak layer of facets together with fresh storm slab. Avoid avalanche terrain.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on many 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)

Avalanches may release spontaneously on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3). Remote triggering is possible.

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

Mye løssnø og kraftig vind vil raskt danne store fokksnøansamlinger, spesielt over ca.1000 moh hvor mildværet ikke tok i helga. Belastningen på vedvarende svake lag vil øke og kan føre til kollaps og store naturlig utløste skred. Nordøstvendte sider vil være mest utsatt.

Unngå skredterreng. Omfattende ustabile forhold mens været står på. Det vil trolig være lett å løse ut skred både innad i fokksnøen og ned på vedvarende svake lag.

Det oppfordres til konservative veivalg med god sikkerhetsmargin. Fjernutløsning av snøskred er mulig.
