Avalanche warning for region Sør-Troms Wednesday 28.02.2018

Danger level 2 - Moderate avalanche danger

Published:
Fresh snow may give instable conditions, especially around Senja, north in the region. Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies.

Avalanche problems

New 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).

Poor bonding between crust and overlying snow

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 28. February 2018

Snøoverflaten er vindpåvirket og består av harde fokksnøflak og skare. Rygger og oppstikkende partier er generelt avblåst. Det er observert overflaterim, hovedsakelig i skog/skoggrensen.

Det finnes kantkornlag under skarelag nede i snødekket. Dette er de fleste steder beskyttet av hard overliggende snø.

Mountain weather

Tuesday 27. February 2018

No precipitation. Fresh breeze from southwest, changing to strong breeze from the southwest during the evening. -14 °C to -7 °C at 1100 m a.s.l. Partly cloudy.

Wednesday 28. February 2018

3 mm precipitation, up to 10 mm in the most exposed areas. Strong breeze from southwest. -10 °C to -5 °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

OPPDATERT 28.2. KL. 10. Nedbørsprognosene er oppjustert for nordlige deler av regionen. Med nysnø i kombinasjon med vind vil skredfaren øke til 2-moderat. Mest utsatt er Senja.
Det gamle snødekket er generelt stabilt, men nysnøen som kommer kan feste seg dårlig til det gamle snødekket pga glatt skare og/eller rim/kantkorn i overflaten. Dypere kantkornlag har vist liten evne til bruddforplantning og vurderes til å ikke utgjøre et skredproblem fordi overliggende lag også er harde.
