Avalanche warning for region Jotunheimen Tuesday 27.02.2018

Danger level 2 - Moderate avalanche danger

Published:
Be careful in areas with windslabs. A persistent weak layer of facets may be triggered, especially where the snow cover is thin.

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).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

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

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)

Monday 26. February 2018

Snødekket over tregrensa er generelt preget av vind med noen cm løs ubundet snø i overflaten. Det finnes fortsatt områder i regionen med løsere snø i skjermede formasjoner, men fokksnø med varierende overflate og hardhet dominerer. I skogen har vind stedvis dannet myke flak, ellers løs snø. Sola har påvirket snøoverflaten i bratt sørvendt terreng.

Dypt begravet kantkorn med overliggende fokksnø med varierende tykkelse er har vært generelt for regionen en stund.
Det ble observert rimkrystaller i overflaten lørdag.
Mandag observert et nytt utviklet kantkornlag rett under nysnøen.

Lørdag noen harmløse løssnøskred observert i Lom, solutløst i S-vendt bratt terreng.

Mountain weather

Monday 26. February 2018

Little to no precipitation. Breeze from northeast, changing to strong breeze from the east during the evening. -19 °C to -8 °C at 1800 m a.s.l. Partly cloudy.

Tuesday 27. February 2018

No precipitation. Moderate gale from east. -25 °C to -15 °C at 1800 m a.s.l. Partly 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

Kuling fra øst vil føre til at fokksnø i vestlig sektor vil øke i omfang og bli hardere. Det kreves mer for at skred løsner, men skredene kan bli noe større.
Vedvarende svake lag kan påvirkes der snødekket er tynt eller mykt.
