Avalanche forecast for Nordenskiöld Land Thursday 2017-03-23

2
Moderate
Published:

There is a persistent weak layer buried in the snow cover that may be triggered by a skier or a snowmobile. Remote triggering possible on hotspots or on convex terrain where the snow cover is thin. Wind slabs may also form avalanches.

2 - Small
Low additional load
Some steep slopes
Possible

Be careful and keep distance to each other in steep (above 30 degrees) terrain 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.

2 - Small
Low additional load

Unlikely

Keep distance to each other and to release areas. NB, remote triggering is possible. 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. Danger signs are whoumpf-sounds, cracking and recent avalanches. However, absence of signs does not mean it is safe.
