Cyclone Tracy.
Cyclone tracy was caused by a huge tropical depression which was a mass of clouds in the arafura which developed into a tropical storm. This storm was unpredictable and changed direction by 90 degrees, heading towards Darwin. This intense tropical storm changed and became a small but very powerful cyclone (what Australians call a hurricane).

How do cyclones form?
Cyclones are formed when warm moist air from the ocean is risen resulting in less air near the oceans surface which results in low air pressure. Regions above or around this low air pressure area have high air pressure and the high air pressure air rushes down to fix the low air pressure. Then the high air pressure moistens and becomes warm and rises up again. This cycle continues and as all the air rises it becomes cooler and develops into clouds, and eventually the cloud development turns into a storm and winds around it make the storm spiral creating a dangerous cyclone. The ocean keeps feeding this cyclone with heat and water evaporating to the sky.
