Avalanche warning for region Svartisen Monday 29.01.2018

Danger level 2 - Moderate avalanche danger

Published:
Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. A weak layer of facets can be present underneath fresh wind deposited snow on isolated features.

Avalanche problems

Wind drifted snow (slab avalanches)

You can 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 some steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1) 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 28. January 2018

Før helgen kom det ca 10 cm nysnø som lørdag er begynt å flytte seg med vinden.

Den gamle snøpakken består flere mildværsskarelag med noe kantkorn i mellom.

Tynnere snødekke ved kysten, men snø til havnivå.

Det er observert ulike lag med kantkorn i snødekket. Særlig under 7-800 moh begynner det å bli futt i kantkornet og det ble lørdag observert store drønn fra snødekket.

Kantkornene dypere i snødekket er svært vanskelig å påvirke.

Søndag er det observert et naturlig utløst flakskred ved Rausandtinden ved Mo i Rana.

Mountain weather

Sunday 28. January 2018

No precipitation. Moderate gale from southeast. -15 °C to -8 °C at 1100 m a.s.l. Clear skies.

Monday 29. January 2018

0 mm precipitation, up to 6 mm in the most exposed areas. Moderate gale from southeast. -13 °C to -6 °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 vil fortsatt kunne danne ferske fokksnøflak i høyfjellet som kan være ustabile. Under mildværsskaren fra tidlig januar er kantkornene nå så svake at de går til brudd, men det er beskjedne mengder snø over dette laget.

Vinden vil trolig ta knekken på de siste restene av overflaterimet som ble dannet tidligere.

Skredfaren ventes som 2-moderat.
