Avalanche warning for region Voss Sunday 23.02.2020

Danger level 3 - Considerable avalanche danger

Published:
Avoid lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger there.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of new snow

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)

Saturday 22. February 2020

Snøoverflata ber preg av store nedbørsmengder og kraftig vind frå sør og vest dei siste dagane. Det har lagt seg opp tydelege fokksnøflak og skavlar, mens ryggar er avblesne.
Det eldre snødekket er smelteomvandla etter mildvêr og gjenfrysing.

Snøgrensa er på omlag 200 moh, men det er spesielt mykje snø over 500 moh.

Det var fredag observert eit stort vått flakskred i Myrkdalen, samt fleire naturleg utløyste skred ved nær Voss.

Mountain weather

Saturday 22. February 2020

40 mm precipitation, up to 60 mm in the most exposed areas. Gale from southwest. -5 °C to -1 °C at 1100 m a.s.l. Cloudy.

Sunday 23. February 2020

6 mm precipitation, up to 12 mm in the most exposed areas. Moderate gale from west, changing to fresh breeze from the west during renoon. -8 °C to -1 °C at 1100 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

Sterk vind frå vest og litt ny nedbør vil gje auka pålagring i austlege leområder og byggje ferske fokksnøflak.

Skredproblemet ligg hovedsakleg i fokksnøen frå dei siste dagane som treng tid på å stabilisere seg. Skred i denne snøen kan verte store og løysast naturleg med auka pålagring.
