Avalanche warning for region Sunnmøre Sunday 08.12.2019

Danger level 3 - Considerable avalanche danger

Published:
Complex situation with persistent weak layers combined with considerable amounts of new snow and wind

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

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)

Saturday 7. December 2019

Siste dagane har det kommet ein god del snø i høgda. Nysnøen er vindpåvirka. Det gamle snødekket er påvirka av mildværet tidlegare i veka. Det gamle snødekket var prega av langvarig kulde som gav mykje laust kantkorn i botn av snødekket. Dette kantkornet er forholdsvis kraftig påvirka av mildværet, men mindre påvirka i høgda.

Observasjon fredag viser at kantkornlaget i botn av snødekket fortsatt er delvis aktivt eller vorte aktivt igjen i høgda. Dette er truleg frå omlag 800- 1000moh.

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

Det er krevande skredforhold i høgda. Eit aktivt kantkornlag i botn av snødekket kan påvirkast av skiløpar, samt at nysnø og vind frå ulike retningar siste dagane gir stadvis store mengder fersk fokksnø i leområder.
