Snow quality
Au-dessus de 2600m indice de risque limité, plus bas indice faible.
Stability: Hivernal en haute altitude, enneigement modeste plus bas.
Déclenchements provoqués : - Au-dessus de 2600/2800 m, les 10/20 cm de neige récente ont été transportés par le vent. En résultent quelques petites instabilités en neige densifiée plutôt identifiables, encore assez réactives. Ces plaques occasionnent de petites avalanches, taille 1. - Dans les versant Nord au dessus de 2800/3000 m, les couches fragiles persistantes sont encore peu enfouies et donc sollicitables. Cassures généralement 30/40 cm, voire 50 cm dans les secteurs mieux servis ce jeudi, le long de la frontière italienne. L'emprise des plaques est encore limitée par l'enneigement modeste, on s'attend donc surtout à des taille 1, en terrain bien dégagé et lisse on peut atteindre la rare taille 2. - Plus bas que 2800/3000 m, le manteau était humide et a partiellement regelé, neutralisant d'éventuelles instabilités.Départs spontanés : petites purges en terrain raide en versants ensoleillés, seulement au delà de 2600/2800 m où la neige est tombée froide.
