Avalanche warning for region Svartisen Wednesday 04.12.2019

Danger level 4 - High avalanche danger

Published:
Rain and mild weather will weaken the snowpack considerably. Keep good distance to avalanche terrain and run out zones for wet avalanches.

Avalanche problems

Wet snow (slab avalanches)

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

Water pooling in/above snow layers

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).

Poor bonding between layers in wind deposited 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)

Tuesday 3. December 2019

Før mildværet satte inn tirsdag var snødekket preget av noe ujevn snøfordeling. I østvendte leområder hadde vinden lagt ifra seg store mengder fokksnø som var ustabil.


Tirsdag meldes det om våte skred mot vei langs kysten.

Tirsdag ettermiddag er mildværet godt igang med plussgrader og regn.

Det er store forskjeller på snømengdene i regionen, mest i indre deler.

Mountain weather

Tuesday 3. December 2019

20 mm precipitation, up to 30 mm in the most exposed areas. Strong breeze from southwest. -8 °C to 2 °C at 1100 m a.s.l. Cloudy.

Wednesday 4. December 2019

20 mm precipitation, up to 45 mm in the most exposed areas. Moderate gale from southwest. -2 °C to 2 °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

Mildvær og relativt store nedbørmengder som regn høyt til fjells ventes onsdag. Det er fare for store naturlig utløste våte skred i tidligere velfylte østlige leområder. I høyfjellet over 1300-1400 moh kan nedbøren komme som snø og det ventes kraftig vind. Det kan danne seg store ustabile områder med fokksnø.
