Avalanche

Indications to skiers, day-trippers and mountaineers |
|
Low |
Triggering is possible only with high additional loads on a few very steep extreme slopes. Only a few small natural avalanches (sluffs) possible. |
Generally favourable conditions for ski-trips |
|
Moderate |
Triggering is possible with high additional loads, particularly on the steep slopes. Large natural avalanches not likely |
Favourable conditions for ski-trips but it is necessary to adequately consider dangerous local zones |
|
Considerable |
Triggering is possible, sometimes even with low additional loads. In certain conditions, medium and occasionally large sized natural avalanches may occur |
The possibility of ski-trips is limited and a good local evaluation is necessary |
|
High |
Triggering is probable even with low additional loads on many steep slopes. In some conditions, frequent medium or large sized natural avalanches are likely |
The possibility of ski-trips is very limited and an high quality local evaluation is necessary |
|
Very high |
Numerous large natural avalanches are likely, even on moderately steep terrain |
Ski-trips are generally impossible |
