Avalanche warning for region Svartisen Friday 30.12.2022

Danger level 2 - Moderate avalanche danger

Published:
Wind deposited snow could rest on a persistent weak layer of facets. In some areas an avalanche can be triggered by snowmobiles

Avalanche problems

Persistent weak layer (slab avalanches)

You can trigger avalanches on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Buried weak layer of surface hoar

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

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 29. December 2022

Over tregrensa er snøen for det meste hard og bærande etter vindpåverknad. Men i områder under tregrensa der vinden ikkje har fått tak kan ein framleis finne laus og mjuk snø og godt skiføre.

Lokalt kan det framleis ligge att nedsnødd svakt lag av overflaterim som vart danna i midten av desember. På fjellet i indre strøk kan det vere svake lag av kantkorn frå kuldeperioden i november.

Mountain weather

Thursday 29. December 2022

2-4 mm precipitation. Rain up to 200 m a.s.l during the afternoon. Strong breeze from southeast, changing to gale from the southeast during renoon. -14 °C to -7 °C at 1100 m a.s.l. Cloudy.

Friday 30. December 2022

4-8 mm precipitation. Rain up to 400 m a.s.l during the afternoon. Gale from southeast, changing to strong breeze from the southeast during renoon. -10 °C to -4 °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

Snødekket vil vere hardt etter kraftig vind i fleire dagar. Dette gjer at det stort sett er vanskeleg å påverke svake lag i snødekket.

Det kan dannast enkelte små ferske flak av vinden og nysnøen som kjem.
