Avoid terrain steeper than 30 degrees and runout zones where the avalanche problem is present. Remote triggering is possible.
NB: Identifying the avalanche problem is very difficult.
Avoid terrain traps.

• 2 Moderate • Mulighet for å løse ut små skred ved liten tilleggsbelastning der det har lagt seg flak av bundet vindtransportert snø. Skredproblemer knytter seg til nedføyket løssnø, men også vedvarebde svakt lag i forbindelse med gamle islag høyt i snødekket. Det er mulig å fjernutløse skred fra slakt terreng. • Noe minkede om det ikke kommer mere snø • Forecast correct

The bulletin does not include a detailed text about the avalanche conditions. This is only given in Norwegian. Translate it using google translate if you like. The text result will be informative, and most likely amusing
For planning your trip and recognizing avalanche terrain, use maps.
Norway has 1:50 000 maps for the whole country. Maps can be bought at bookstores and sports shops, or printed from the net.
For slope angle maps, download the app Varsom Regobs on App Store | Google Play or see our slope angle map at senorge.no ("helning" means slope angle).
Modelled snowpack and historic and current weather information can be found on the webpage senorge.no. This site uses information from the weather stations and interpolate values from the stations for gridded maps.
Detailed weather forecast can be found online at www.yr.no or www.storm.no. Yr.no is also in English, but the weather in text format is only given in Norwegian.
