Avalanche warning for region Svartisen Tuesday 14.12.2021

Danger level 2 - Moderate avalanche danger

Published:
Avoid areas with fresh wind deposited snow. There could be persistent weak layers under the the wind slabs.

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 easily trigger avalanches 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.

Buried weak layer of faceted snow near surface

Wet snow (loose snow avalanches)

Avalanches may release spontaneously 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)

Monday 13. December 2021

Snøen er ujevnt fordelt i terrenget. Flere steder over tregrensen er det avblåst til skare eller bar bakke, mens det ligger hardere fokksnøflak i lesider og forsenkinger.

I åpne områder rundt tregrensen og i skogen har vinden lagt opp mykere fokksnøflak. Snødekket i skogen består av 20-30 cm mykere og løsere snø uten noen såle under.



Under fokksnøen ligger det svake lag av kantkorn og overflaterim. Lave temperaturer og tynt snødekke gjør at det er gode forhold for videre utvikling av svake lag.

Det ligger mest snø høyt til fjells og i vestvendte terrengformasjoner.

Mountain weather

Monday 13. December 2021

5 mm precipitation, up to 10 mm in the most exposed areas. Rain up to 600 m a.s.l during renoon. Breeze from southeast, changing to strong breeze from the southeast during the afternoon. -6 °C to -1 °C at 1100 m a.s.l. Cloudy.

Tuesday 14. December 2021

13 mm precipitation, up to 35 mm in the most exposed areas. Rain up to 500 m a.s.l during the afternoon. Strong breeze from south, changing to moderate gale from the south during the evening. -6 °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

Vind i kombinasjon med nysnø gjør at det vil legge seg opp fokksnøflak som er store nok til å begrave en skiløper. Det vil være lett å løse ut skred i sjiktovergangen, eller der fokksnøen legger seg over vedvarende svake lag i det gamle snødekket.

Mildvær og regn gjør at det vil kunne løsne enkelte middels store løssnøskred.

Husk at selv små skred kan skade deg, særlig nå som det er mye oppstikkende steiner.
