Avalanche warning for region Vest-Telemark Wednesday 01.01.2020

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

Wind drifted 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).

Poor bonding between layers in wind deposited snow

Persistent weak layer (slab avalanches)

You can 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)

Tuesday 31. December 2019

Mildvær siste dager med påfølgende lavere temperatur har gitt skare mange steder opptil ca 1000-1100 moh. Høyere til fjells har nedbøren kommet som snø. Vestlig sterk vind har gitt ferske fokksnøflak i lesider mot Ø og NØ.

Det er tidligere observert nedsnødd rim ved Rauland, men der mildværet har virket er nok dette brutt ned.

Mountain weather

Tuesday 31. December 2019

Little to no precipitation. Moderate gale from northwest. -6 °C to 0 °C at 1100 m a.s.l. Partly cloudy.

Wednesday 1. January 2020

No precipitation. Strong breeze from west. -3 °C to 3 °C at 1100 m a.s.l. Partly 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

Ferske fokksnøflak er det dominerende skredproblemet. Økende omfang med høyden. Over mildværsgrensen vil svakt lag med nedsnødd rim være lite påvirket av mildværet og kan dermed være et problem der snødekket er tynt/mykt. Lenger ned i terrenget vil fokksnø ligge på varierende grad av skare som vil gi varierende grad av feste for den ferske fokksnøen.
