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

Avalanche Problems

• Buried weak layer of faceted snow beneath a crust • Within half a meter • The collapsing weak layer is thin < 3 cm. A big and identifiable crystal in the weak layer. • N, NE, E, SE, S, SW, W, NW above 300 masl

Weather

• No precipitation • -3 °C • 5 m/s from NW ↘ • 100% clouds

Avalanche Danger Assessment

• Det er meldt mildvær fra fredag, men det er usikkert om det påvirker kantkornlaget fra 3-400m og oppover

Snow Cover

• No snowdrift • Storm slab (soft slab) • Dry • 20cm fokksnø i forsenkninger og bak rygger. 5cm på plasser hvor det er flatt. Ellers avblåst ned til bakken, spesielt i sydlig eksposisjon. Det observeres ett tydelig kantkornlag under skare, generelt i fjellet over 300moh. Krystallene har fasetter, men klarte ikke å observere stepp eller 120 grader. Laget var heller ikke så luftig, men svært sprøtt

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.
