1. Sea surface temperatures rise above 26.5°C

2. Water evaporates and warm, humid air rises

3. Rising air cools, causing moisture to condense into clouds. Droplets form, releasing even more heat to power the storm. Low pressure over the sea draws more air upwards

4. The system spins as air rushes to the centre to fill the low pressure void

5. Once sustained winds reach 74mph, it is classified as a hurricane
