What Is a Hurricane?

A hurricane is a warm core, low pressure weather system that has an organized circulation.

Depending on the location, the system may be called a hurricane (Atlantic/Eastern Pacific Ocean), a typhoon (western Pacific), or a cyclone (Indian Ocean).

The storm can be as small as Tropical Cyclone Tracey, which was about sixty miles wide when it struck in Australia in 1974. Or it can be as big as Typhoon Tip, which reached over 1200 miles in width in the northwest Pacific Ocean in 1979.
