   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. A tempest is a sudden and violent storm, such as
          those common on the coast of Italy, where the term
          originated, and is usually attended by a heavy rain,
          with lightning and thunder.

                Storms beat, and rolls the main; O! beat those
                storms, and roll the seas, in vain. --Pope.

                What at first was called a gust, the same Hath
                now a storm's, anon a tempest's name. --Donne.
