Avalanche warning for region Tromsø Thursday 16.01.2020

Danger level 2 - Moderate avalanche danger

Published:
Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger here.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches 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)

Wednesday 15. January 2020

I lavlandet der mildværet tok er det nå skare de fleste steder.
Over tregrensen består snødekket av harde fokksnøflak, enkelte steder med løsere snø og ellers avblåst til gammel skare.

Fredag kunne det sees antydning til kantkorndannelse under skare på ca. 750 moh, men generelt virker det vanskelig å løse ut større skred i gamle kantkornlag nå.

Mandag ble det observert kraftig snøfokk i høyden.
Tirsdag meldes det om lite løs snø over skogen.

Mountain weather

Wednesday 15. January 2020

3-7 mm precipitation. Fresh breeze from east, changing to strong breeze from the northeast during the afternoon. -8 °C to -2 °C at 700 m a.s.l. Cloudy.

Thursday 16. January 2020

Little to no precipitation. Fresh breeze from east. -8 °C to -3 °C at 700 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

Vinden minker og det kommer lite ny snø. Fokksnøen (der den finnes) vil stabilisere seg og det skal mer til for å løse ut skred.

Høyt til fjells kan det finnes vedvarende svake lag av kantkorn dypere i snødekket, men disse utgjør pr. nå ikke et aktivt skredproblem.
