Avalanche problems
Wind drifted snow (slab avalanches)
You can very 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)
Avalanches may release spontaneously on a few 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 above a crust
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.
Snow cover (in Norwegian), 20.03.2023
Store lokale variasjoner i snøoverflate. Under skoggrensen og i skjermede formasjoner finnes det fortsatt en del løssnø. På utsatte steder er det harde fokksnø flak etter sterk vind fra ulike retning under de siste dagene.
Det har utviklet seg vedvarende svake lag av kantkorn rundt skarelag under fokksnø. Observasjoner på lørdag tyder på at der dette lag kan påvirkes, så viser den gode evne til bruddforplantning.
På søndag meldes det om kraftig snøfokk på fjellet. På lørdag ble det rapportert inn noen store drønn i nærheten av Bomfjellet.
