1 low: Triggering is generally possible only with high additional loads (e.g. groups without intervals) and on very steep, extreme slopes. Only a few small natural avalanches (sluffs) possible. Generally safe conditions.
2 moderate: Triggering possible in particular with high additional loads, particularly on the steep slopes indicated in the bulletin. Large natural avalanches not likely. Favourable conditions, for the most part. Routes should be selected with care, in particular on steep slopes, and at the altitude indicated in the bulletin.
3 considerable: Triggering possible even with low additional loads (e.g. single person), particularly on the steep slopes indicated in the bulletin. In some conditions, medium and occasionally large natural avalanches may occur. Partly unfavourable conditions. Experience in avalanche hazard assessment required. Avoid steep slopes at the altitude indicated in the bulletin if possible.
4 high: Triggering probable even with low additional loads on many steep slopes. In some conditions, many medium and several large natural avalanches are likely. Unfavourable conditions. Great experience in avalanche hazard assessment required. Limitation to moderately steep terrain; take care of run out zones.
5 very high: Numerous large natural avalanches are likely, even in moderately steep terrain. Very unfavourable conditions. Renunciation recommended.
