Avalanche forecast for Jotunheimen Thursday 2019-02-14

3
Considerable
Published:

Precipitation as rain leads to higher avalanche danger. A weak layer deep in the snow pack can now become more active. Avoid fresh stormslabs above the new snow line.

Wind drifted snow (slab avalanches)

Buried weak layer of new 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.
3 - Large
Low additional load
Many steep slopes
Possible

Persistent weak layer (slab avalanches)

Buried weak layer of faceted snow near surface

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.
3 - Large
Low additional load
Many steep slopes
Possible

Wet snow (slab avalanches)

Water pooling in/above snow layers

Avoid avalanche release and run out areas. Wet snow avalanches tend to release spontaneously. Stability decreases when the snow surface gets wet and soft. Timing is important.
3 - Large
Spontaneous release
Some steep slopes
Possible

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.
