Avalanche problems

Persistent weak layer (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). Remote triggering is possible.

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 3. February 2023

Det var rolig vær og ingen nedbør av betydning de siste dagene. I starten av uken kom det 15-25 cm nedbør, mest ved kysten. Det gamle snødekket består stort sett av skare og smelteformer uten farlig lagdelingen. Over det ligger det mye løs snø i lavereliggende og vindskjermet terreng. I høyden er det fokksnø av varierende hardhet. Det har også dannet seg rim på overflaten etter kaldt og klart vær.

Det har utvikle seg et lag av kantkorn høyt i snødekke over skaren og under snøen som kom etter mildværet forrige helg.

Mountain weather

Friday 3. February 2023

No precipitation. Fresh breeze from southeast, changing to breeze from the southwest during the evening. -19 °C to -7 °C at 1100 m a.s.l. Clear skies.

Saturday 4. February 2023

4 mm precipitation, up to 10 mm in the most exposed areas. Rain up to 200 m a.s.l during the evening. Fresh breeze from south, changing to strong breeze from the south during the evening. -24 °C to -7 °C at 1100 m a.s.l. 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

Skredfaren ventes å øke til betydelig om kvelden. Økende vind mot kvelden vil danne ferske fokknsøflak. Skred kan løses ut i et svakt lag av kantkorn og/eller rim som ligger høyt i snødekket. Faren vil være størst der vinden har pakket overliggende snø til hardere flak.
