Avalanche warning for region Vest-Telemark Monday 24.12.2018

Danger level 2 - Moderate avalanche danger

Published:
Increasing wind gives increase in avalanche dager during afternoon and evening. Be careful in areas with fresh wind deposited snow. Be aware that there can be pockets with persistent weak layer beneath wind deposited snow.

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).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches can get large enough to bury or even kill you (size 2). Remote triggering is possible.

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 23. December 2018

Snøoverflaten er i varierende grad vindpåvirket og fokksnøen veksler mellom harde og myke flak. Mest fokksnø ligger i N- og V-vendte fjellsider. Stedvis finnes det også en del løs snø som kan flyttes av vind. I skogen er snøen i mindre grad vindpåvirket. Det er fortsatt mindre snø enn normalt for årstiden.

Onsdag ble det observert nedsnødd rim i snødekket både ved Rauland og Haukeliseter, men utbredelsen er usikker.

Fredag løste skiløper ut et lite skred (str.1) i nordvendt heng ved Haukeliseter.

Søndag er det generelt rolige vindforhold og oppholdsvær.

Mountain weather

Sunday 23. December 2018

No precipitation. Fresh breeze from northwest. -15 °C to -7 °C at 1400 m a.s.l. Partly cloudy.

Monday 24. December 2018

2-6 mm precipitation. Fresh breeze from northwest, changing to moderate gale from the northwest during the evening. -10 °C to -2 °C at 1400 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

Økende vind utover dagen vil flytte tilgjengelig løs snø inn i leområder, hovedsakelig mot Ø-SØ. Dette vil gi økende skredfare utover dagen når vinden tar seg opp. Stedvis finnes også vedvarende svakt lag av rim i snødekket, men utbredelsen og egenskapene til dette laget er usikkert.
