Avalanche warning for region Sunnmøre Wednesday 23.12.2020

Danger level 2 - Moderate avalanche danger

Published:
Wind and fresh snow may give instable conditions in some slopes. Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger. Avoid convex terrain.

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).

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)

Tuesday 22. December 2020

Snødekket er generelt tynt og snøoverflata varierer mellom skare og is og fokksnø av ulik hardleik. Mildvêr førre held fukta snødekket til fjelltopphøgde.

Snøgrensa ligg på 400-700 moh, og er lågast i indre deler av regionen.

Ein venter at observert overflatekantkorn er øydelagt av mildvêr ila laurdag.
Kantkorn ved bakken vert ikkje rekna som eit aktivt skredproblem då det ligg under bærande snø/skare.

Det var måndag observert fersk vindtransportert snø nær Volda.

Mountain weather

Tuesday 22. December 2020

8-12 mm precipitation. Strong breeze from southeast, changing to fresh breeze from the west during the evening. -7 °C to -3 °C at 1400 m a.s.l. Cloudy.

Wednesday 23. December 2020

20 mm precipitation, up to 30 mm in the most exposed areas. Fresh breeze from northwest. -9 °C to -2 °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

Mykje nedbør og sterk vind frå nordvest vil gje stor snøtransport til søraustlege leområder. Dette vil gje pålagring og nysnøflak over 600 moh.

Ein lyt òg vere merksam på eldre flak som stadvis kan ligge på glatt skare i alle himmelretningar.
