Avalanche warning for region Svartisen Monday 11.04.2022

Danger level 3 - Considerable avalanche danger

Published:
The situation is tricky, conservative terrain choices are recommended. Multiple avalanche problems are expected. Newly formed wind slabs can be triggered. Wet loose avalanches are likely in the afternoon as the sun heats the new snow. Old persistent weak layers can be triggered and produce large avalanches.

Avalanche problems

Persistent weak layer (slab avalanches)

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

Buried weak layer of faceted snow near surface

New snow (slab avalanches)

You can trigger avalanches 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 some steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

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)

Sunday 10. April 2022

Snøoverflaten varierer fra løs og ubunden snø i vindskjermede områder. Der vinden har fått flyttet på snøen, ligger det myke og litt hardere fokksnøflak.

Det er observert kantkornlag forholdvis høyt oppe i snødekket mellom lag av fokksnø. Det er også observert kantkornlag i overgangen mellom den gamle skare og overliggende fokksnølag.

Fredag er det observert tydelige faretegn fra snødekket og skred har blitt løst ut fra avstand.

Mountain weather

Sunday 10. April 2022

10 mm precipitation, up to 15 mm in the most exposed areas. Rain up to 300 m a.s.l during renoon. Moderate gale from southeast, changing to fresh breeze from the east during the afternoon. -8 °C to -3 °C at 1100 m a.s.l. Partly cloudy.

Monday 11. April 2022

Little to no precipitation. Breeze from east, changing to breeze from the northwest during the afternoon. -18 °C to -4 °C at 1100 m a.s.l. Clear skies.

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

Situasjonen ventes å være krevende med flere ulike skredproblem. Konservative turvalg anbefales.

Det mest alvorlige problemet er knyttet til svake lag av kantkorn. Det er lett løse ut store skred, også fra avstand (fjernutløsning). Problemet er mest utbredt i indre strøk.

Fokksnøflakene som ble dannet søndag ventes å stabilisere seg raskt. Men det kan være mulig å løse ut skred noen steder.

Utover ettermiddag kan det naturlig utløste skred når sola varmer opp nysnøen i bratte solhellinger.
