Avalanche warning for region Sør-Troms Wednesday 07.03.2018

Danger level 2 - Moderate avalanche danger

Published:
Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind deposited slabs are 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).

Poor bonding between layers in wind deposited 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)

Tuesday 6. March 2018

Det er kommet 0-10 cm nysnø siste uke med lokale variasjoner. Snøoverflaten er påvirket av vinden mange steder og i leområder ligger det fokksnøflak med varierende tykkelse. Fokksnøen har mange steder lagt seg på gammel hard fokksnø eller på hard og isete skare. Andre steder er det avblåst helt ned til gammel skareoverflate.

Det finnes flere vedvarende svake lag av kantkorn tilknyttet skarelag nede i snødekket. De svake lagene er de fleste steder beskyttet av hard overliggende snø, eller de ligger under skare uten flak over.

Mountain weather

Tuesday 6. March 2018

No precipitation. Fresh breeze from southeast. -21 °C to -12 °C at 1100 m a.s.l. Clear skies.

Wednesday 7. March 2018

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

Stabilt vær medfører en generell stabilisering av eldre fokksnøflak, og disse vil generelt være vanskelig å løse ut. Litt vind kan føre til enkelte små ferske fokksnøflak, men dette ventes å ha liten utbredelse.
