Avalanche forecast for Svartisen Wednesday 2019-02-13

3
Considerable
Published:

The snowpack is unstable. Avoid areas with wind-deposited snow. It is also possible to trigger avalanches in a persistant weak layer in old snow.

New snow (slab avalanches)

Buried weak layer of new snow

Avoid terrain traps and steep slopes until the new snow has stabilized. The avalanche problem is generally widely distributed on any steep slope with deep new snow. Look for cohesive new snow that breaks apart or is poorly bonded to the old snow. Cracks around your skis are a typical dangersign.
3 - Large
Spontaneous release
Some steep slopes
Possible

Persistent weak layer (slab avalanches)

Buried weak layer of faceted snow beneath 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.
3 - Large
High additional load
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.
