Avalanche warning for region Hallingdal Thursday 05.12.2019

Danger level 2 - Moderate avalanche danger

Published:
It is possible to release small to moderate big avalanches in the fresh snow. Persistent weak layers are a problem at high elevations.

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)

Wednesday 4. December 2019

Tirsdag og onsdagens mildvær har fuktet øvre del av snøpakka helt opp til 800-1000 moh. I lavereliggende områder er snøen gjennomfuktet. Mest snø finner man i østlige og nordvendte leområder.

Det finnes kantkornet snø ved bakken, men snøen må trolig ligge på glatte flater av litt størrelse for at det skal skje brudd av betydning.

Både tirsdag og onsdag har det vært plussgrader opp til 800-1200 moh.

Mountain weather

Wednesday 4. December 2019

1-3 mm precipitation. Strong breeze from west. -4 °C to 0 °C at 1400 m a.s.l. Partly cloudy.

Thursday 5. December 2019

6 mm precipitation, up to 20 mm in the most exposed areas. Gale from southwest, changing to strong breeze from the southwest during the afternoon. -5 °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

Nedbør og kraftig vind vil gi ferske fokksnøflak i nordøstvendte hellinger. Her vil det være lett å løse ut skred.
Det kan fortsatt være mulig å løse ut skred i svakt lag av kantkornlag ved bakken.
I lavereliggende områder kan det gå enkelte våte løssnøskred.
