Weather forecasts and field observations are reliable.
Highly unfavourable conditions. Avoid open terrai.
The snowpack is poorly bonded and largely unstable in general.
Numerous very large and often extremely large natural avalanches can be expected, even in moderately steep terrain*.
Unfavourable conditions.Extensive experience in the assessment of avalanche danger is required. Remain in moderately steep terrain / heed avalanche run out zones
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 large and often very large natural avalanches can be expected.
Partially unfavourable conditions.Experience in the assessment of avalanche danger is required. Steep slopes of indicated aspects and altitude zones should be avoided if possible
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 certain situations some large, and in isolated cases very large natural avalanches are possible.
Mostly favourable conditions. Careful route selection, especially on steep slopes of indicated aspects and altitude zones.
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*. Very large natural avalanches are unlikely
Generally safe conditions.
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 small and medium natural avalanches are possible.
* The avalanche-prone locations are described in greater detail in the avalanche bulletin (altitude, slope aspect, type of terrain).
• moderately steep terrain: slopes shallower than about 30 degrees
• steep slopes: slopes steeper than about 30 degrees
• very steep, extreme terrain: particularly adverse terrain related to slope angle (more than about 40 degrees), terrain profile, proximity to ridge, smoothness of underlying ground surface
** Additional loads:
• low: individual skier / snowboarder, riding softly, not falling; snowshoer; group with good spacing (minimum 10m) keeping distances
• high: two or more skiers / snowboarders etc. without good spacing (or without intervals); snowmachine; explosives
natural: without human influence

The predicted level of danger of the avalanche is in accordance with the European Avalanche Danger scale (www.avalanche.org).
and the icons used to describe the principle avalanche warnings are consistent with those specified by the Utah Avalanche Centre (www.utahavalanchecenter.org).
The terms used for the predictions are also consistent with the specifications of the Centre de Prediccion de Lauegi (www.lauegi.conselharan.org)
