THUN'DER-STORM, n. [thunder and storm.]

A storm accompanied with lightning and thunder. Thunder clouds are often driven by violent winds. In America, the violence of the wind at the commencement, is sometimes equal to that of a hurricane, and at this time the explosions of electricity are the most terrible. This violence of the wind seldom continues longer than a few minutes, and after this subsides, the rain continues, but the peals of thunder are less frequent. These violent showers sometimes continue for hours; more generally, they are of shorter duration.
