Avalanche forecast for Voss Thursday 2019-01-24

2
Moderate
Published:

Be aware of isolated wind slabs above treeline, otherwise stable conditions.

Wind drifted snow (slab avalanches)

Buried weak layer of new snow

Be careful and keep distance to each other in steep (above 30 degrees) terrain with fresh wind deposited snow, especially convex terrain. An avalanche is easier to trigger where wind slabs are thin or soft. Look for areas where the wind recently has deposited snow, typically behind ridges, ribs and in gullies. Remember that local wind effects will cause variation in where the wind slabs occur.

Poor bonding between layers in wind deposited snow

Notes

Overflatenær fasettering har pågått i 10 cm tjukt lag under eit topplokk av 4F vindpakka RG. Dette er ikkje skredproblem akkurat her, men viser at motoren har vært i sving.

Cornice fall

Incident

Var svært bevist og klar over skredfaren, men da det var mørkt og snøføyke var det ikkje sikt nok til å kunne ta trygge linjeval til kvar ei tid. Kom til eit bratt parti, og antok då at snøen kom til å skil ut i det eg slapp seg over skavlen, noko det også gjorde. I det eg kjem over skavlen innser eg at eg har tatt feil av storleiken på terrengformasjonen, som er større enn antatt. Følgeleg blir det som ein forventa skulle bli eit handterbart skavlbrot stort nok til å kunne begrave ein person. Mista skia og blir delvis begravd, fann att skia på ein meters djup etter kort tid.

Did not affect anything
