Avalanche warning for region Heiane Friday 18.02.2022

Danger level 2 - Moderate avalanche danger

Published:
The danger increases when the wind picks up. Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies.

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)

Thursday 17. February 2022

Opp til ca 700moh er snøen fuktig. Høyere oppe er det skare med nysnø over, denne er ubunden flere steder. Der vinden har tatt er det alt fra myk til hard fokksnø.
I østvendte leområder over tregrensen ligger det et tykt og jevnt snødekke, men det er mer avblåst i vestvendt terreng.


På ca 850 moh ved Hunnedalen nær Øvstabøstølen ble det observert et tykt kantkornlag under et tykt skarelag. Kantkornlaget er ikke et skredproblem siden det ligger dypt i snødekket under bærende og tykk skare. Utbredelsen av kantkornlaget er usikker.

Mountain weather

Thursday 17. February 2022

10 mm precipitation, up to 20 mm in the most exposed areas. Rain up to 500 m a.s.l during the afternoon. Fresh breeze from east, changing to strong breeze from the west during the afternoon. -7 °C to -2 °C at 1100 m a.s.l. Cloudy.

Friday 18. February 2022

10 mm precipitation, up to 15 mm in the most exposed areas. Rain up to 400 m a.s.l Friday night. Moderate gale from west, changing to fresh breeze from the northeast during the evening. -7 °C to -2 °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

Økende vind fører til mer snøtransport og det kan være lett å løse ut skred mens været står på. Stabiliseringen vil skje raskt da det er milde temperaturer og det vil roe seg allerede på kvelden.
