Avalanche forecast for Nordenskiöld Land Monday 2017-01-23

3
Considerable
Published:

Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies, primary in eastern slopes. Avalanches in this layer may be triggered by a single skier. A persistent weak layer of facets may be triggered, especially where the snowcover is thin or by avalanches in the wind deposited snow.

Wind slab avalanches

Poor bonding between layers in wind deposited snow
Slab avalanche
2 - Small
Low additional load
Many steep slopes
Possible

Avoid steep (more than 30 degrees) areas with fresh wind deposited snow, especially convex terrain. An avalanche is easier to trigger where wind slabs are thin or soft. Look for areas where the wind recently has deposited snow, typically behind ridges, ribs and in gullies. Remember that local wind effects will cause variation in where the wind slabs occur.

Persistent deep slab avalanches

Buried weak layer of faceted snow near the ground
Slab avalanche
3 - Medium
High additional load
Many steep slopes
Possible

Avoid steep terrain (more then 30 degrees) and runout zones. NB, remote triggering is possible. You should not expect danger signs like whoumpf-sounds, cracking and recent avalanches when the weak layer are deep in the snowpack. Triggering of the weak layer are normaly only expected with large additional weight. Make very conservative route choices, especially in unknown terrain, after snowfall and if temperatures rise. Identifying areas where the weak layer is present might be difficult and requires experience.

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.

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.
