Avalanche warning for region Vest-Telemark Tuesday 18.02.2020

Danger level 3 - Considerable avalanche danger

Published:
Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Naturally released loose avalanches can occur.

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).

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)

Monday 17. February 2020

Snøoverflaten består av fokksnø med ulik hardhet og utbredelse etter vind og snø siste døgn. Det er også mye snø tilgjengelig for transport. Rygger og vindutsatte partier er stedvis avblåst ned til gammel skare. Natt til søndag var det plussgrader opp til ca 1000 moh.

Eldre, vedvarende svake lag med kantkorn ligger stort sett under bærende snødekke og anses ikke som et aktivt skredproblem nå.

Mandag formiddag er det plussgrader opp til ca 800 m og det meldes om kraftig snøfokk på 950 moh i Rauland. Det har kommet 5-25 mm nedbør siste døgn, mest vest i regionen. Det er ventet at nedbøren skal fortsette utover mandagen.

Mountain weather

Monday 17. February 2020

10 mm precipitation, up to 25 mm in the most exposed areas. Gale from southwest, changing to moderate gale from the southwest during the evening. -4 °C to 0 °C at 1100 m a.s.l. Cloudy.

Tuesday 18. February 2020

6 mm precipitation, up to 12 mm in the most exposed areas. Moderate gale from southwest, changing to fresh breeze from the southwest during the evening. -5 °C to -1 °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

Vind og fortsatt påfyll av nysnø vil gi ferske fokksnøflak i høyden, hovedsaklig i nordøstvendte heng. Stedvis kan disse løses ut naturlig. Det er ventet mest nysnø i den vestliggende delen av regionen. Skredfaren er avtagende utover dagen.
