Avalanche warning for region Hallingdal Tuesday 14.04.2020

Danger level 2 - Moderate avalanche danger

Published:
Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger here.

Avalanche problems

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).

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)

Monday 13. April 2020

Siste døgnet har mildvær og gjenfrysing gitt smelte/fryse-skare under ca 1000 moh. Over mildværsgrensa har nysnø og sterk vind gitt ferske fokksnøflak i østlige fjellsider. Det ligger mye snø i terrenget. I østlige fjellsider er det bygget opp stedvis store skavler den siste tiden. Kuler og rygger mot vest er stedvis avblåst til gamle skarelag.

Det er tidligere observert svake lag av kantkorn rundt skarelag nede i snødekket og ved bakken. Vedvarende svake lag ligger for det meste under solid skare og vurderes nå til ikke å være et aktivt skredproblem.

Søndag formiddag har Hemsedal skisenter (1344moh) V stiv kuling og -8 grader. Kommet opp mot 15 cm nysnø i regionen siste døgn.

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

Vind og litt nysnø kan gi myke fokksnøflak i østvendte fjellsider. Det kan være mulig for en skiløper å løse ut skred i disse. Ellers stabile forhold.
