Avalanche warning for region Sunnmøre Sunday 21.04.2019

Danger level 1 - Low avalanche danger

Published:
Favorable conditions. Rain and some snow high up give increased danger of wet avalanches. Glide avalanches are possible.

Avalanche problems

Wet snow (loose snow avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

Loose snow

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).

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)

Saturday 20. April 2019

Det har vore høge temperaturar i fjellet og snødekket i låglandet er for det meste grovkorna og stabilt. I høgfjellet over ca 900 meter er snøoverflata meir variert, med smelteomvandla snøpakke i sørvendte fjellsider og framleis ein del lagdelt vindpakka tørr snø i nord- og skyggesider. Natt til laurdag melder observatør i Ørsta om fråværande nattefrost.

Det har lokalt vore observert kantkornutvikling høgt i snødekket grunna låga nattetemperaturar, men omfanget påvirkar skredfaren i liten grad. Høgt til fjells finst det òg kantkorn djupare i snødekket.

Det er laurdag observert nokre våte laussnøskred i Ørsta.

Mountain weather

Saturday 20. April 2019

1-3 mm precipitation. Fresh breeze from south, changing to strong breeze from the southwest during the afternoon. -1 °C to 7 °C at 1400 m a.s.l. Clear skies.

Sunday 21. April 2019

5 mm precipitation, up to 10 mm in the most exposed areas. Fresh breeze from southwest, changing to breeze from the southwest during renoon. -4 °C to 4 °C at 1400 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

Synkande temperatur virkar generelt stabiliserande på snødekket. Litt nedbør og vind kan dog legge opp nokre ferske fokksnøflak i nordaustlege leområder over 1000 moh. Stabiliteten i snødekket vil svekkast når temperaturen stig utover dagen. I låglandet kan ein få mindre våte lausnøskred.
