Avalanche warning for region Sunnmøre Friday 20.12.2019

Danger level 2 - Moderate avalanche danger

Published:
Be careful in terrain where you find fresh wind deposited snow. Weak layers beneath the new snow can be triggered by a skier.

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).

Persistent weak layer (slab avalanches)

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

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)

Thursday 19. December 2019

Kraftig vind frå søraust har gitt snøtransport inn i nordvestlege leheng siste døgnet. Snødekket er generelt prega av mykje vind i det siste med avblesne ryggar og mykje snø i typiske leområder. Det djupaste snødekket er mildverspåvirka.

Det finst svakt lag kantkorn mot bakken i høgda. Det er òg observert eit lag kantkorn høgre i snødekket som føreløpig ikkje har vist teikn til brotforplantning.

Det var onsdag observert overflaterim i snøen på Melshornet, men i dette området blanda i lausar snø og utgjer då ikkje noko stort problem.

Mountain weather

Thursday 19. December 2019

5 mm precipitation, up to 12 mm in the most exposed areas. Strong breeze from southeast. -9 °C to -2 °C at 1400 m a.s.l. Cloudy.

Friday 20. December 2019

4 mm precipitation, up to 10 mm in the most exposed areas. Fresh breeze from southeast, changing to strong breeze from the southeast during the evening. -5 °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

Pågåande sterk vind frå søraust og litt ny nedbør vil gje snøtransport til nordvestlege leområder. Her vil ein få auka pålagring og ferske fokksnøflak.
Nokre stadar kan det forventast vedvarande svake lag som er mogleg å påvirke. Utbreiinga og orienteringa av desse er vanskeleg å stadfeste.
