WebPowder avalanche. Powder avalanches are dry avalanches with a track that runs over larger escarpments. The masses of snow accelerate due to the freefall and mix with the air. Depending upon how much snow rushes over the escarpment, powder avalanches can be harmless (spindrift) or create an enormous air blast – with major destructive potential.
