Syn: Tempest; violence; agitation; calamity.

Usage: {Storm}, {Tempest}. Storm is violent agitation, a commotion of the elements by wind, etc., but not necessarily implying the fall of anything from the clouds. Hence, to call a mere fall or rain without wind a storm is a departure from the true sense of the word.
