  1. 1. The most powerful storm is the hurricane.
  2. 2. <ul><li>It is a large, swirling, low-pressure system that forms over the mid Atlantic ocean. </li></ul><ul><li>Its like a machine that turns the heat energy from the ocean into wind. </li></ul><ul><li>Similar storms are called typhoons and cyclones but there not as strong </li></ul>
  3. 3. <ul><li>There are several elements that—when combined at the &quot;right&quot; amount of time and under the &quot;right&quot; conditions—will create a hurricane </li></ul><ul><li>The beginning of life for any hurricane is a pre-existing tropical disturbance—an area of low atmospheric pressure </li></ul><ul><li>The warmth and moisture of the ocean during late summer and early fall months energizes the pre-storm conditions and leads to thunderstorms. </li></ul>
  4. 4. <ul><li>If thunderstorms persist and winds pick up to 40 miles per hour, the tropical disturbance officially becomes a tropical storm. </li></ul><ul><li>After a set amount of time, if the heat and water moisture continue to rise it will eventually turn into a hurricane. </li></ul>
  5. 5. <ul><li>When a hurricane strikes land, high wind, tornadoes, heavy rains, and high waves cause a lot of damage. </li></ul><ul><li>Floods from the rain can cause additional damage </li></ul><ul><li>Hurricane weather can destroy crops, demolish buildings, kill people, and other animals.. </li></ul><ul><li>As long as its over water, the warm, moist air rises and provides energy for the storm. </li></ul>
