OBS

Il en résulte : augmentation de la densité et de la résistance de la neige.

CONT

[...] plus l'intensité [de la chute de neige] diminue, plus la métamorphose et le tassement du manteau (donc sa consolidation) ont le temps de se réaliser; le risque [d'avalanche] s'en trouve alors diminué à terme plus ou moins long.
