Avalanche warning for region Heiane Friday 31.01.2020

Danger level 2 - Moderate avalanche danger

Published:
Wind and fresh snow may give instable conditions in higher areas. Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Under 1000 masl rising temperature and rain may give wet avalanches.

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).

Buried weak layer of new 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)

Thursday 30. January 2020

Snødekket er generelt preget av mye vind og nedbør som både regn og snø den siste tiden. Lavere enn 1200 moh er det gamle snødekket gjennomfuktet og stabilt og den nye snøen fra tidligere i uken var relativt fuktig da den kom og stabiliserte seg raskt.

Over 1000-1200 moh var snøen tørrere da den kom og i leområder er det fokksnø av varierende hardhet. Der vinden har fått herje er det avblåst til barmark eller skare.

Fra Sirdal blir det rapportert om synlige sigesprekker i nærheten av områder der det allerede har løsnet glideskred.

Mountain weather

Thursday 30. January 2020

12 mm precipitation, up to 20 mm in the most exposed areas. Breeze from southeast, changing to fresh breeze from the southeast during the afternoon. -6 °C to -1 °C at 1100 m a.s.l. Cloudy.

Friday 31. January 2020

8 mm precipitation, up to 15 mm in the most exposed areas. Breeze from south, changing to fresh breeze from the southwest during renoon. -3 °C to 1 °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

I høyden vil snø og vind fornye problemet med ferske, ustabile nysnøflak i lenheng. Dreiende vind gjør at vi etter hvert vil ha ferske flakdannelser både i V, N og Ø.

Under ca 1000 vil stigende temperatur og regn kunne gi våte skred i bratt terreng.
Det er også fare for glideskred, unngå opphold under sigesprekker.
