Avalanche warning for region Vest-Finnmark Saturday 04.01.2020

Danger level 3 - Considerable avalanche danger

Published:
Be careful in areas with fresh wind deposited snow. Old persistent weak layers exist in the snow cover, and are easy to trigger in some places.

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 above a crust

Wind drifted 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).

Poor bonding between layers in wind deposited snow

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)

Friday 3. January 2020

Torsdag var det forbigåande mildvær opp til ca. 800 moh, samt nedbør og sterk vind. Dette har påverka snødekket og har gitt tynn regnskare under mildværsgrensa og vindpåverka snø i fjellet.

Under gamle fokksnøflak er det stadvis svakt lag av kantkorn. Dette ligg vekselvis under, over og mellom porøse skarelag. Torsdag vart det observert mange drønn og skytande sprekker når laget blei påverka.

Det gjekk skred på veg mellom Øksfjord og Myrnes fredag morgon. Det har også gått to naturleg utløyste flakskred i Koppartindgryta dei siste dagane.

Mountain weather

Friday 3. January 2020

6 mm precipitation, up to 12 mm in the most exposed areas. Fresh breeze from southwest, changing to strong breeze from the northwest during the evening. -10 °C to -1 °C at 1100 m a.s.l. Partly cloudy.

Saturday 4. January 2020

6-10 mm precipitation. Moderate gale from northwest. -13 °C to -6 °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

Det finnast allereie nysnø- og fokksnøflak i fjellet, og nye vil bli danna når vinden dreier mot NV og gir meir nedbør og vind. Det kan då vere mogleg å løyse ut flakskred i mange himmelretningar. Vedvarande svake lag finnast i snødekket og påverknad av desse kan gi store skred.
