Avalanche warning for region Sør-Troms Thursday 08.03.2018

Danger level 2 - Moderate avalanche danger

Published:
Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Slab avalanche is easiest to trigger where the wind deposited slabs are soft.

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).

Poor bonding between layers in wind deposited snow

Persistent weak layer (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). 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)

Wednesday 7. March 2018

I slutten av forrige uke kom det 5-10 cm nysnø. Mange steder har denne snøen blitt flyttet på av vind fra SV-V, særlig i ytre strøk. Men stedvis ligger det ca 5cm løs ubunden snø på overflaten.

Det finnes flere vedvarende svake lag av kantkorn nede i snødekket. De svake lagene er de fleste steder beskyttet av hard overliggende snø, eller de ligger under tynn skare uten flak over. Noen få steder kan ferske fokksnøflak ligge oppå den tynne skaren.

Mountain weather

Wednesday 7. March 2018

No precipitation. Fresh breeze from southeast. -20 °C to -13 °C at 1100 m a.s.l. Partly cloudy.

Thursday 8. March 2018

No precipitation. Fresh breeze from southeast. -21 °C to -12 °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

Stabilt vær medfører at fokksnøflak gradvis stabiliseres, og disse vil generelt være vanskelig å løse ut. Litt vind kan føre til enkelte små ferske ustabile fokksnøflak, men dette ventes å ha liten utbredelse. Vær likevel obs på at det noen få steder kan finnes vedvarende svake lag av kantkorn under fokksnø, og der dette evt finnes vil snøen være ustabil lenge.
