Snow quality
Indice de risque faible.
Stability: FAIBLE ENNEIGEMENT SUR LE MASSIF, RISQUE FAIBLE
Départs provoqués : Dans les faces Nord sommitales (au-dessus de 2700 / 2800m), quelques instabilités de surface peuvent demeurer dans la neige récente, parfois travaillée par le vent. Elles deviennent plus dures à déclencher, et restent de petites tailles, les quantités de neige mobilisables étant faibles. Départs spontanés : Peu probables.
