Avalanche warning for region Sunnmøre Saturday 11.02.2023

Danger level 2 - Moderate avalanche danger

Published:
Avalanches can be easy to trigger in wind slabs at the highest peaks, and in wet snow lower in the terrain.

Avalanche problems

Wet snow (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Water pooling in/above snow layers

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)

Friday 10. February 2023

Det har vore skiftande vêr den siste tida. Torsdag kom det 10-30 cm nysnø i kombinasjon med vind, men eit frontsystem med nedbør og mildare temperaturar kom fredag ettermiddag. Snøoverflata vil difor vere våt under mildvêrsgrensa som er meldt opptil 1200 moh. Høgare enn dette vil det vere vindpåverka snø av varierande hardheit.

Djupare i snødekket er det observert kantkornlag rundt gamal mildvêrsskare. Desse har gitt utslag i stabilitetstestar, men det er ikkje kjent at det har ført til skred. Laget kan moglegens påverkast nokre få stadar.

Mountain weather

Friday 10. February 2023

25 mm precipitation, up to 50 mm in the most exposed areas. Rain up to 1200 m a.s.l during the evening. Strong breeze from west, changing to strong breeze from the southwest during the afternoon. -12 °C to -3 °C at 1400 m a.s.l. Cloudy.

Saturday 11. February 2023

12 mm precipitation, up to 25 mm in the most exposed areas. Rain up to 1200 m a.s.l during the evening. Fresh breeze from west, changing to strong breeze from the southwest during the evening. -4 °C to 0 °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

Skred er mogleg å løyse ut i våt snø under mildvêrsgrensa og i tørr fokksnø over mildvêrsgrensa.

Snøen som har kome dei siste dagane kan ha blitt svært våt og dermed ustabil etter mykje regn fredagskveld og natt til laurdag.

I høgda har det samla seg mykje fokksnø i leheng dei siste dagane, og sjølv om mildvêr gjer at denne stabiliserar seg relativt raskt, kan det vere mogleg å løyse ut skred nokre stadar.
