Avalanche warning for region Sunnmøre Monday 22.04.2024

Danger level 2 - Moderate avalanche danger

Published:
Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Wind deposited snow could rest on a weak layer of buried surface hoar.

Avalanche problems

Persistent weak layer (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2). Remote triggering is possible.

Buried weak layer of faceted snow near surface

Wet snow (loose snow 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)

Sunday 21. April 2024

Det er nysnø over regionen etter snøfall laurdag. Nysnøgrense på omlag 100moh, men det smeltar raskt i låglandet.
I skuggevendte botnar i høgda er det truleg kantkorn under nysnøen, på hardt underlag.

Det gamle snødekket er stabilt, hardt og i stor grad smelteomdanna.

Snøgrensen til det eldre snødekket går rundt 400-700 moh.

Vêrforholda siste tid før snøfallet gir høve for kantkorndanning i overflata.

Mountain weather

Sunday 21. April 2024

Little to no precipitation. Calm/light breeze from northeast. -12 °C to 1 °C at 1400 m a.s.l. Clear skies.

Monday 22. April 2024

2-5 mm precipitation. Rain up to 600 m a.s.l during the afternoon. Breeze from southwest. -10 °C to 1 °C at 1400 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

Mjuke fokksnøflak frå snøfallet laurdag ligg på kantkorn/ rim i skuggevendte botnar i høgda. Denne snøen har no fått stabilisert seg ein del, men flaka kan truleg lett bli løyst ut av skiløpar. Det harde, eldre snødekket gjer at brudd i flaka forplantar godt, og forsterkar såleis skredproblemet.
Vær derfor varsom i slike terrengformer. Sprekker og drønn i snøen er tydelige teikn.

Utpå dagen når varmen stig kan det være lett for skiløpar å løyse ut våte skred i nysnøen.

Ved sigesprekker er det forhold for glideskred.
