Avalanche forecast for Nordenskiöld Land Thursday 2019-02-14

2
Moderate
Published:

Wind deposited snow could rest on a persistent weak layer of facets. In some areas an avalanche can be triggered by snowmobiles. There are wind-slabs in the high mountains, most in eastern part of the region.

Wind drifted snow (slab avalanches)

Poor bonding between layers in wind deposited snow

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 - Medium
High additional load
Some steep slopes
Possible

Persistent weak layer (slab avalanches)

Buried weak layer of faceted snow near surface

Keep distance to each other when traveling in avelanche terrain. 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 and cracking which means that you influence weak layers and should avoid avalanche terrain. However, absence of signs does not mean it is safe.
3 - Large
High additional load
Some steep slopes
Unlikely

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.

Visit www.ut.no for topographic maps online. For slope angle maps, see NGI slope angel maps ("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.
