Avalanche warning for region Voss Wednesday 14.02.2018

Danger level 3 - Considerable avalanche danger

Published:
Be careful in areas with fresh wind deposited snow. There may be pockets with a persistent weak layer beneath the wind deposited snow.

Avalanche problems

New snow (slab avalanches)

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

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)

Tuesday 13. February 2018

Mykje vind i helga har ført til danning av fokksnøflak i leområder over skoggrensa. Ryggar og andre utsatte terrengformasjonar er avblåst og det har danna seg store skavlar, særskilt i nordlig sektor.

I snødekket er det observert kantkorn ved skarelaget som blei danna 23.12. Desse er utvikla i ulik grad. Enkelte stadar kan det også vere nedsnødd rim.

Det blei observert fleire skred i fjella aust for Øvre Rong på mandag.

Mountain weather

Tuesday 13. February 2018

Little to no precipitation. Breeze from southeast, changing to strong breeze from the south during the evening. -13 °C to -6 °C at 1400 m a.s.l. Partly cloudy.

Wednesday 14. February 2018

12 mm precipitation, up to 18 mm in the most exposed areas. Strong breeze from south, changing to strong gale from the south during the evening. -8 °C to -4 °C at 1400 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

Nedbør som snø saman med ubunden snø i terrenget vil i kombinasjon med sterk vind frå sør føre til danning av nysnøflak i leområder over skoggrensa. Vinden skal auke frå stiv kuling til liten storm på kvelden, som også fører til auka snøskredfare. Det finnast kantkornlag i snødekket som kan påverkast der snødekket er tynt.
