Avalanche bulletin for the Lyngen Alps

On varsom.no you will find information about the snowpack and the avalanche conditions. The avalanche problems are of principal concern to the user. Knowing what causes avalanches can make it easier for you to avoid them.

Norwegian Avalanche Forecast Centre have created the homepage with inspiration from other alp countries like Canada, France and Switzerland.

Norwegian Water Resources and Energy Directorate have observer courses where they teach the participants how to move safely in the mountains and how they can measure risks. Visit Lyngenfjord are paying one of these courses a visit. Twenty people from different parts of Norway have gathered for three days education in weather, notification tools and snow profiles.

- We are getting special knowledge during these days but anyone who has made observations can report it to www.regobs.no. It is about time this homepage came up and a very good tool that everyone should use! Says one of the trained skier who reports daily to the service.

Avalanche danger scale

Danger level


Snowpack stability

Avalanche triggering probability

5 - Very high


The snowpack   is poorly bonded and largely unstable in general.

Numerous   large-sized and often very large-sized natural avalanches can be expected,   even in moderately steep terrain.

4 - High


The snowpack   is poorly bonded on most steep slopes.

Triggering   is likely even from low additional loads** on many steep slopes. In some   cases, numerous medium-sized and often large-sized natural avalanches can be   expected.

3 - Considerable


The snowpack   is moderately to poorly bonded on many steep slopes*.

Triggering   is possible, even from low additional loads** particularly on the indicated   steep slopes*. In some cases medium-sized, in isolated cases large-sized   natural avalanches are possible.

2 - Moderate


The snowpack   is only moderately well bonded on some steep slopes*, otherwise well bonded   in general.

Triggering   is possible primarily from high additional loads**, particularly on the   indicated steep slopes*. Large-sized   natural avalanches are unlikely.

1 - Low


The snowpack   is well bonded and stable in general.

Triggering   is generally possible only from high additional loads** in isolated areas of   very steep, extreme terrain. Only   sluffs and small-sized natural avalanches are possible.

Temperature: Temperature rise makes weaker bindings in the snow and the risk for avalanches increases.

Sun: Sunshine makes the snow binding weaker and affects the sunny cardinals.

Snowfall: When new snow falls, there is additional loads to the weak layer under.

Rain: Rain makes the snowpack heavier and the snow crystals weaker.

Wind: Wind creates snow edges and moves the snow to wind free areas that is changing the structure in the snow.

Human factors

It is important to know the group when going on a ski trip in the Lyngenalps. These are some measurable factors when judging the stability in the group.

- Communication and leadership. Does the group have a clear leader? How are you going to communicate during the tour and is it possible to be open with your own skills and limits?

-Size of the group. The bigger group, the more risks is it when going on a tour.

- X-factors. Unexpected happenings, for example a broken ski or an accident. What are the preparations for that?

Group dynamic

You can divide groups in three different categories.

  1. Fragile. The group is big; the participants have limited experience and there are no one leading the group.
  2. Conscious. The group is not that big, there is a guide leading the group and you are aware about the variety in the skiers’ experiences.
  3. Strong. A small group with a well-planned tour, the participants have ski experience and good knowledge about avalanches.

The group dynamic is an important factor when assessing avalanche risks. It is a big part of the human factor and


Keep you updated on www.varsom.no for your own safety and do not forget the important equipment:

- Avalanche transceiver. This tool transmits and receives signals from other avalanche applicants.

- Search stick. 2,5-3 metres is a good length.

- Shovel. The shovel should be strong so you can dig into hard, packed snow and ice without breaking or bending.

- Helmet and back plate. These are cheap life insurances.
