Avalanche warning for region Sunnmøre Sunday 21.04.2024

Danger level 2 - Moderate avalanche danger

Published:
Avoid areas with fresh wind deposited snow. There could be buried surface hoar under the the wind slabs.

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)

Avalanches may release spontaneously 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 2024

Det er nysnø over regionen etter snøfall laurdag. Nysnøgrense på omlag 200moh. I skuggevendte botnar i høgda er det truleg kantkorn under nysnøen, på hardt underlag.

Det gamle snødekket er stabilt og i stor grad smelteomdanna.

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

Vêrforholda siste tid gir høve for kantkorndanning i overflata.
Observasjon på dette i naboregion.

Mountain weather

Saturday 20. April 2024

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

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 truleg på kantkorn/ rim i skuggevendte botnar. Desse flaka kan 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.

Der sola får tilstrekkelig tak kan det lausne små og middels store skred av seg sjølv.

Ved sigesprekker er det forhold for glideskred.
