Highest danger level per day:
2
Moderate
Published:

Avoid avalanche terrain with newly deposited wind slabs. The wind slabs are overlying a persistent weak layer, and avalanches can therefor be easier to trigger and get bigger than if persistent weak layers were absent.

Advice

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

Avalanche problems

Persistent weak layer (slab avalanches)

Buried weak layer of faceted snow beneath a crust

Avalanche Problems

• Dry slab avalanche • The weak layer collapses easily and clean (easy propagation). • Difficult to trigger • 1 - Small • W, NW above 900 masl

Snow Cover

• 90 cm in total • Some snow drift • 30 cm new snow • Much loose snow (10-30cm) • Moist

Danger Sign

• Recent snowdrift • Område: I denne fjellsiden. Beskrivelse: Innblåst nysnø i NV hellinger

Weather

• -3 °C • 6 m/s from NW ↘ • 100% clouds • Tett tåke og vind med snø i lufta. Dårlig sikt. Ca 10-50m med hodelykt.

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.
