Avalanche warning for region Tromsø Monday 24.02.2020

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 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 23. February 2020

De siste dagene har vinden bearbeidet snøen mange steder så snøen er ujevnt fordelt og vindpåvirket i forskjellig grad. På de mest vindutsatte stedene er det avblåst til eldre skare, mens det i leområder fortsatt kan ligge mykere snø.

Gammelt snødekke består i stor grad av ulike skarelag og smelteomvandlet snø.

Det finnes et vedvarende svakt lag av kantkorn enkelte steder i regionen.

Fredag ble det observert flere middels store flakskred over tregrensa i ytre strøk av regionen.

Mountain weather

Sunday 23. February 2020

8 mm precipitation, up to 16 mm in the most exposed areas. Fresh breeze from southwest, changing to fresh breeze from the north during the afternoon. -7 °C to 0 °C at 700 m a.s.l. Cloudy.

Monday 24. February 2020

7 mm precipitation, up to 14 mm in the most exposed areas. Strong breeze from northwest, changing to breeze from the northwest during the afternoon. -10 °C to -2 °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

Natt til mandag øker vinden på fra NV med bygenedbør. Dette vil føre til økt pålagring på snødekket og dannelse av ustabile fokksnøflak i høyden.

Det finnes også svake lag av kantkorn lenger ned i snødekket, men disse virker foreløpig vanskelig å påvirke.
