Avalanche warning for region Hallingdal Thursday 13.01.2022

Danger level 3 - Considerable avalanche danger

Published:
Wet avalanches can release in steep terrain because of rain. Fresh vind slabs are a problem at higher elevations.

Avalanche problems

Wet snow (slab avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Water pooling in/above snow layers

Wind drifted snow (slab avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

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)

Wednesday 12. January 2022

Snøoverflaten består i varierende grad av vindpåvirket snø med innslag av løsere nysnø. Der vinden ikke har tatt tak er det 10-30 cm løssnø. På de mest vindutsatte stedene er det avblåst til skare.
Under ca, 1200 moh er det gamle snødekket i varierende grad påvirket av smelte-fryseprosesser og det finnes skarelag flere steder.
Det er fortsatt noe oppstikkende stein og vegetasjon.

Over ca. 1200 moh finnes kantkorn omkring skarelag i snødekket og ved bakken. Det finnes i alle himmelretninger, men mest i Ø-vendt terreng.

Mountain weather

Wednesday 12. January 2022

5 mm precipitation, up to 30 mm in the most exposed areas. Rain up to 1400 m a.s.l during the afternoon. Moderate gale from west, changing to strong gale from the west during the afternoon. -4 °C to 2 °C at 1400 m a.s.l. Cloudy.

Thursday 13. January 2022

18 mm precipitation, up to 35 mm in the most exposed areas. Rain up to 1400 m a.s.l Thursday night. Gale from west, changing to storm from the west during the afternoon. -2 °C to 2 °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 i form av regn vil svekke snødekket og skred kan løsne naturlig. Temperaturen synker i løpet av dagen, og da vil også snøgrensen synke. Mot ettermiddag kan det bli dannet ferske fokksnøflak i leheng i høyfjellet på grunn av nysnø og svært sterk vind. Så lenge været står på kan skred løsne naturlig her også.
