Avalanche warning for region Hardanger Thursday 15.02.2018

Danger level 3 - Considerable avalanche danger

Published:
Avoid areas with fresh windloaded snow. Avoid lee areas where a persistent weak layer can be hidden in the snow pack. Avalanches are triggered most easily where the snow pack is thin, typically close to ridges and on convex formations.

Avalanche problems

New snow (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).

Buried weak layer of new snow

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)

Wednesday 14. February 2018

Nysnøen som kom før helga blei påverka i ulik grad av vind frå aust i helga. Mange stadar danna det seg fokksnøflak, men enkelte stadar er det framleis mykje snø tilgjengeleg til vindtransport.

I snødekket er det observert kantkorn ved skarelaget som blei danna 23.12. Desse er utvikla i ulik grad i regionen og ligg stadvis djupt i snødekket, men observatør meldte fredag at kantkornlaget er tynt og bryt lett og glatt nær Sauda skisenter.

Det blei søndag observert mange flakskred og sprekker i snøen ved påverknad av skiløpar.

Thursday 15. February 2018

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

Nedbør som snø saman med ubunden snø i terrenget vil i kombinasjon med sterk vind frå søraust føre til danning av nysnøflak i leområder over skoggrensa. Mest snø skal komme i sør- og vestlege delar av regionen og skredfaren vil difor vere størst her. Det finnast kantkornlag i snødekket som kan påverkast der snødekket er tynt.
