PROBABILITY
INDICATIONS
RISK 1
WEAK
In most of the slopes the snowy mantle is well stabilized.
Exceptionally, avalanches can only be triggered on some very favorable slopes (*).
Excursions and ski descents are possible almost without restrictions.
RISK 2
LIMITED
On some slopes (**) sufficiently favorable to avalanches, the mantle is only moderately stabilized. In the rest, it is well stabilized.
Avalanches can be triggered mainly by strong overloads (***) and on some slopes whose characteristics are normally described in the bulletin. Spontaneous outflows of large avalanches are not expected.
Excursions must be made with prior planning. Caution is recommended when choosing itineraries, avoiding, as far as possible, sloping slopes with the indicated orientation and altitude.
RISK 3
REMARKABLE
On numerous (**) auspicious slopes, the mantle is only moderately or weakly stabilized.
Avalanches can be triggered even by weak overloads and on numerous slopes whose characteristics are commonly described in the bulletin. In certain situations, some spontaneous outflows of avalanches of medium and sometimes large dimensions are possible.
Sloping slopes in the indicated orientations and altitudes should be avoided. A lot of experience is required and a great capacity to appreciate the avalanche danger.
RISK 4
STRONG
On most of the slopes (**) sufficiently favorable to avalanches, the snowy mantle is weakly stabilized
Avalanches can be triggered even by weak overloads on most slopes sufficiently conducive to them. In certain situations, numerous spontaneous outbreaks of avalanches of medium dimensions and sometimes large are possible.
Excursions have to be limited to areas with moderate slopes. It is possible that the lower part of the slopes is equally exposed to avalanche danger.
RISK 5
VERY STRONG
General instability of the snowy mantle.
Many large spontaneous avalanches are expected, including areas with less than favorable slopes.
You have to give up on excursions.

(*) Slopes conducive to avalanches are those that have certain conditions of inclination, configuration of the terrain, proximity of the ridge 

(**) The characteristics of these slopes are generally specified in the bulletin: altitude, exposure, topography 

(***) Strong overload: for example, grouped skiers 

Weak overload: for example, isolated skier or mountaineer.

The term avalanche triggering refers to those caused by an overload, mainly by one or more skiers.

The expression spontaneous exit refers to avalanches originated without external action.
