Avalanche forecast for Lyngen Sunday 2019-01-20

2
Moderate
Published:

Light snow showers might create small windslabs and it might be easy to trigger small avalanches in the new snow. This is type of weather might give more snow and wind than forecasted. The old persistent weak layer of facets deep in the snow pack is still present, even without danger signals from the snowpack.

New snow (slab avalanches)

Buried weak layer of new snow

Be careful in steep slopes and around terrain traps 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.
2 - Medium
Low additional load
Isolated 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.
