Avalanche warning for region Jotunheimen Saturday 28.12.2019

Danger level 2 - Moderate avalanche danger

Published:
There is a persistent weak layer buried in the snow cover that may be triggered by a skier or snowmobile. Remote triggering possible on hotspots or on convex terrain where the snow cover is thin. Use caution in steep terrain with wind deposited snow.

Avalanche problems

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).

Buried weak layer of faceted snow near the ground

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)

Friday 27. December 2019

Nysnø uten vind har stedvis gitt en myk snøoverflate, men mange steder er det et tynt skarelag i snøoverflaten med løs snø under. Snømengden varierer med terrenget, med lite snø i vindutsatte områder og mer snø i leområder.

Det finnes vedvarende svake lag av begerkrystaller ved bakken og kantkorn høyere i snødekket.

Det ble rapportert om et str 2 skiløperutløst skred SØ for Vennisfjellet torsdag.

Det ble meldt om moderat snøfokk med vind fra V torsdag. Rim på hardt underlag ble observert 23.12.

Mountain weather

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

Vedvarende svake lag i snødekket kan påvirkes av skiløpere der snødekket er tynt. Vær oppmerksom på drønn i snødekket, fjernutløsning er mulig. Det oppfordres til konservative veivalg da skred som løsner i begerkrystaller ved bakken kan bli store.
Vind fra SV og nysnø gir fersk fokksnø i leheng som kan løses ut av en skiløper.
