Avalanche warning for region Tromsø Monday 11.12.2017

Danger level 2 - Moderate avalanche danger

Published:
There is a persistent weak layer buried in the snow pack, especially at tree line. Be careful in areas with wind deposited snow.

Avalanche problems

Persistent weak layer (slab avalanches)

You can 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 faceted snow beneath a crust

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).

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 10. December 2017

Det har vært lite nedbør siden torsdag. Vinden har blåst kraftig fra SØ siden fredag og dannet fokksnøflak i leformasjoner. I vindskjermede områder har det dannet seg myke flak eller snøen er fortsatt løs.

Nede i snødekket er det et kantkornlag fra november, men det er ikke observert mye aktivitet fra dette de siste dagene i denne regionen.

Det er ikke observert skredaktivitet de siste dagene.

Mountain weather

Sunday 10. December 2017

Little to no precipitation. Strong breeze from southeast. -4 °C to -2 °C at 700 m a.s.l. Partly cloudy.

Monday 11. December 2017

No precipitation. Breeze from southeast. -8 °C to -2 °C at 700 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

Vinden roer seg litt og ferske flak ventes å være lite utbredt og tynne på grunn av lite snø tilgjengelig for transport. Eldre fokksnøflak som ble dannet før og i løpet av helgen ventes å ha stabilisert seg nå. Der snødekket er tynt er det fare for å løse ut skred i et kantkornlag dypere i snødekket. Skredfaren vurderes til 2-moderat.
