Avalanche warning for region Jotunheimen Friday 20.01.2023

Danger level 3 - Considerable avalanche danger

Published:
Conditions are dangerous. Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Be aware of a persistant weak layer buried by windslabs.

Avalanche problems

Persistent weak layer (slab avalanches)

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

Buried weak layer of faceted snow near the ground

Wind drifted snow (slab avalanches)

You can 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)

Thursday 19. January 2023

Det ligger fokksnøflak med varierende fasthet i terrenget etter perioder med vind og nedbør siste dagene. Mange steder har nok flakene begynt å få godt feste til underlaget, men fortsatt finnes det ustabile fokksnøflak. Det ligger mye tørr løssnø i skjermede formasjoner.

Velutviklet kantkorn ved bakken har jevnlig gitt drønn flere steder, og det har tidligere blitt observert skred på dette laget nord og vest i regionen.

Mountain weather

Thursday 19. January 2023

No precipitation. Breeze from southwest. -16 °C to -9 °C at 1800 m a.s.l. Partly cloudy.

Friday 20. January 2023

No precipitation. Calm/light breeze from west. -27 °C to -9 °C at 1800 m a.s.l. Clear skies.

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

Vedvarende svakt lag med kantkorn ved bakken kan være mulig å påvirke, hovedsaklig der snødekket er tynt.
Rolig vær gir eldre fokksnø tid til gradvis stabilisering, men det kan fortsatt være mulig å løse ut skred i denne.
