今(26)日下午風起雲湧，一道強烈的積雨雲經過大多倫多地區，以近安大略湖稍南的地區尤為強烈。對流層的積雨雲發展成熟，大粒冰雹連同雷暴、陣風、大雨一同降臨多倫多大地。

冰雹 (Hail) 是在對流雲所形成的積雨雲中形成，當水汽隨氣流上升遇冷會凝結成小水滴，若隨著高度增加溫度繼續降低，達到攝氏零度以下時，水滴就凝結成冰粒；在它上升運動過程中，並會吸附其周圍小冰粒或水滴而增大，直到因其重量增加而下降，當其降落至較高溫度區時，其表面會融解成水；同時亦會吸附周圍的小水滴，此時若又遇強大之上升氣流再被抬升，其凝結成冰粒又不斷凝結變大，直到因自身重量而下落。若降到地面時未融化解成水,則仍呈固態的冰粒或冰雹。
