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.

O! beat those storms, and roll the seas, in vain. --Pope.
