Avalanche warning for region Heiane Thursday 19.12.2019

Danger level 3 - Considerable avalanche danger

Published:
The danger increases when the wind picks up. Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies.

Avalanche problems

Wind drifted snow (slab avalanches)

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

Buried weak layer of new snow

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)

Wednesday 18. December 2019

Det ligg laussnø i overflata etter nedbør under rolege vindforhold. Det eldre snødekket ber generelt preg av kraftig vind siste perioden med avblesne ryggar og mykje snø i typiske leformasjonar. I låglandet er snødekket i stor grad påvirka av varme og fuktigheit.

Det har tidlegare vore observert svakt lag kantkorn ved bakken, men omfanget og utbreiinga av dette er usikkert etter kraftig mildvêr førre veke.

Mountain weather

Wednesday 18. December 2019

3-6 mm precipitation. Breeze from west. -5 °C to -1 °C at 1100 m a.s.l. Cloudy.

Thursday 19. December 2019

10 mm precipitation, up to 20 mm in the most exposed areas. Gale from southeast, changing to moderate gale from the southeast during the afternoon. -5 °C to 0 °C at 1100 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

Kraftig vind og mykje ny nedbør vil gje stor snøtransport inn i hovedsakleg nordvestlege leområder. Stigande temperatur vil svekke bindingar i snødekket.
