Avalanche warning for region Svartisen Sunday 12.01.2020

Danger level 3 - Considerable avalanche danger

Published:
Challenging conditions due to several different avalanche problems. Conservative terrain choice is essential on freshly loaded storm slabs in the alpine. Wet snow in lower elevations and risk of avalanche releasing in full depth.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of new snow

Wet 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)

Saturday 11. January 2020

Mildvær i begynnelsen av uka førte til at snødekket under nysnøen er gjennomfuktet og generelt stabilt opp til ca 800 moh. Snøbyger i fjellet og kraftig vind fra V har flyttet på mye av løs snø i høyden og dannet myke fokksnøflak i leområder. På mer vindutsatte steder er det avblåst ned til bakken eller til gammel skare.

Observasjoner lørdag ved Storforshei tilsier 10-30 cm ubunden snø i beskyttede områder over ca. 250 moh. Økende vind har dannet fokksnøflak.

Mountain weather

Saturday 11. January 2020

20 mm precipitation, up to 40 mm in the most exposed areas. Moderate gale from south. -7 °C to -2 °C at 1100 m a.s.l. Cloudy.

Sunday 12. January 2020

15 mm precipitation, up to 25 mm in the most exposed areas. Gale from southwest, changing to strong breeze from the southwest during renoon. -7 °C to -2 °C at 1100 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

Fortsatt snøbyger i kombinasjon med sterk vind vil legge opp fersk fokksnø. Forholdsvis milde temperatur fører til at fokksnøflakene stabiliseres ganske raskt.
Synkende temperaturer bidrar til at mulighetene for våte skred under mildværsgrensen minker.
