Avalanche forecast for Nord-Troms Monday 2019-02-18

3
Considerable
Published:

Avoid avalanche terrain with newly deposited wind slabs. Persistent weak layers can be effected, particularly awith the tree line and where the snow cover is thin.

Wind drifted snow (slab avalanches)

Poor bonding between layers in wind deposited snow

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.
2 - Medium
Low additional load
Many steep slopes
Possible

Persistent weak layer (slab avalanches)

Buried weak layer of faceted snow above a crust

Avoid skiing in avalanche terrain (steep terrain more than 30 degrees and in runout zones). NB, remote triggering is likely. 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.

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.
