Hurricane Fact Sheet

By: Gayle Olson

Hurricane Fact Sheet

  • A hurricane is a large whirling storm that usually measures 200 to 500 miles (320 to 800 km) across. 
  • The eye of the hurricane averages 14-25 miles (22-40 km) across. The eye is quite calm as compared to the winds in the eye wall.
  • On the average each year, six Atlantic hurricanes occur. There are 5 different types of hurricane categories.
  • Hurrican Season.
    In the North Atlantic hurricane season is from June 1 to November 30. Over the Western Pacific, the typical cyclone season is never quite over.
  • The winds of the hurricane spin in a counterclockwise direction in the Northern Hemisphere and clockwise in the Southern Hemisphere.
  • Sustained winds of 100-150 mph (160-240 km/h) occur with a typical hurricane. Some winds may exceed 200 mph (320 km/h).

  • As it travels across the ocean, a hurricane may pick up as much as two billion tons of water each day through evaporation and sea spray.
  • Some two million metric tons of air are circulated inFree Articles, up and out of the hurricane each second.

Heat from Hurricanes

  • If the heat released by an average hurricane in one day could be converted to electricity, it could supply the United States' electrical needs for about six months.
  • The heat energy released in a single day can equal the energy released by the fusion of four hundred 20-megaton hydrogen bombs.
