Hurricanes are products of a tropical ocean and atmosphere.
Powered by heat from the sea, they are steered by the easterly trade winds and the temperate westerlies as well as by their own ferocious energy. Around their core, winds grow with great velocity, generating violent seas. Moving ashore, they sweep the ocean inward while spawning tornadoes and producing torrential rains and floods. Of these five, two will be major hurricanes, category 3 or greater on the Saffir-Simpson Hurricane Scale . The first use of a proper name for a tropical storm was by Clement Wragge, an Australian forecaster early in this century.
