Avalanche warning for region Svartisen Sunday 28.01.2018

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 easily 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)

Saturday 27. January 2018

I fjellet er snøoverflaten preget av skare og hard fokksnø. Fokksnøen kom med den kraftige vinden som sto på fra sør og øst forrige uke. Det er tidligere observert overflaterim mange steder.

Før helgen kom det ca 10 cm nysnø som fortsatt ligger ubundet.

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.

Det finnes kantkornlag dypere i snødekket under tykke skarelag, men disse er svært vanskelig å påvirke.

Ikke observert skredaktivitet de siste dagene.

Mountain weather

Saturday 27. January 2018

No precipitation. Breeze from southeast, changing to moderate gale from the southeast during the evening. -18 °C to -8 °C at 1100 m a.s.l. Clear skies.

Sunday 28. January 2018

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

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.
