Avalanche warning for region Hallingdal Saturday 29.01.2022

Danger level 3 - Considerable avalanche danger

Published:
Precipitation and strong wind will create fresh wind slabs in lee areas. Rain on snow can produce wet avalanches. Naturally triggered avalanches are possible.

Avalanche problems

Wind drifted snow (slab avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Buried weak layer of new snow

Wet snow (loose snow avalanches)

Avalanches may release spontaneously on a few steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Loose snow

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few 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)

Friday 28. January 2022

Store deler av regionen har tynt snødekke. Det er bare i høyfjellet lengst vest snødybden er normal for årstiden. Utsatte formasjoner avblåst til mildværsskare eller bar bakke, mens det er en god del innblåst snø i skjermede formasjoner i østlige fjellsider. Stein, lyng og busker stikker opp fra snøen.

Over 1200 moh finnes vedvarende svake lag under fokksnøen og det finnes begerkrystaller ved bakken. Kantkornlagene er for det meste dekket av tykk og fast fokksnø, men skredaktivitet sist lørdag viser at lagene er mulige å påvirke.

Mountain weather

Friday 28. January 2022

3 mm precipitation, up to 8 mm in the most exposed areas. Rain up to 400 m a.s.l during the evening. Fresh breeze from northwest, changing to moderate gale from the southwest during the afternoon. -10 °C to -4 °C at 1400 m a.s.l. Partly cloudy.

Saturday 29. January 2022

15 mm precipitation, up to 35 mm in the most exposed areas. Rain up to 1200 m a.s.l during renoon. Strong breeze from southwest, changing to gale from the northwest during the afternoon. -9 °C to 1 °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

Mye nedbør og sterk vind vil danne store ferske fokksnøflak i østvendte fjellsider i høyfjellet. Naturlig utløste skred er sannsynlig.
Milde temperaturer gir regn på snø opp til ca 1100-1300 moh. og det kan gå naturlig utløste våte løssnøskred. Utover ettermiddagen vil lavere temperatur og snøbyger gi en gunstig oppbygging av de ferske flakene under ca 1100-1200moh.
Skredfaren vil være størst i vest, der det kommer mest nedbør.
