Answer:
Temperature plays a huge role in the type of avalanche that you might witness along with the human urbanization. When the temperature is high, the top slopes of the snow mountains start to weaken and that can cause them to loose their position and fall down.
Too much heat cause snow to liquefy whereas slight warmth will cause dry ice avalanche or powder form avalanche. In some conditions, a whole chunk of the ice mountain can fall given the temperature is not supportive.
