In meteorology, a tropical cyclone (also referred to as a hurricane, typhoon, tropical storm, cyclonic storm, tropical depression, and simply cyclone depending on strength and geographical context) is a storm system characterized by a low pressure center and numerous thunderstorms which generally forms in the tropics. While they can be highly destructive, tropical cyclones are an important part of the atmospheric circulation system, which moves heat from the equatorial region toward the higher latitudes. They develop over large bodies of warm water, and lose their strength if they move over land. This is the reason coastal regions can receive significant damage from a tropical cyclone, while inland regions are relatively safe from receiving strong winds.

Cyclone Tracy at landfall.
Cyclone Tracy was a tropical cyclone that devastated Darwin, Australia, from December 24 to December 25, 1974. It was recorded by The Age as being a "disaster of the first magnitude...without parallel in Australia's history." It killed 71 people - the official death toll was revised upwards from 65 to 71 in March 2005 - and destroyed over 70 percent of Darwin's buildings, leaving over 20,000 people homeless. Most of Darwin's population was evacuated to Adelaide, Whyalla, Alice Springs and Sydney, and many never returned to Darwin. The town was subsequently rebuilt with modern materials and techniques. Cyclone Tracy was at least a Category 4 storm, although there is evidence to suggest that it had reached Category 5 when it made landfall at Darwin.
