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

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

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

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

Varselet er basert på et enklere datagrunnlag enn regionale varsler og utgis kun for faregrad 4 og 5

Det er mye snø fjellet i regionen nå, og i utsatte strøk ventes betydelige mengder nysnø over skoggrensa i kombinasjon med sterk vind. Skredfaren øker til 4- stor lørdag. Skiftende vindretning gjennom dagen gjør at det vil legge seg ferske fokksnøflak i mange himmelretninger. Det vil særlig være stor skredfare i områder der fokksnøen ligger oppå nedføyka kantkorn og/eller overflaterim.

Under snøgrensa (ca 500 moh) kan det være fare for våte snøskred i forbindelse med regn på snødekket.

Situasjonen er krevende og det forventes naturlig utløste skred!
