Outline the formation of a tropical storm?

Tropical storms occur mainly along the east coast of America near to Florida, around the Indian ocean and at above 5' North and South of the Equator. In order for a Tropical revolving storm to form the water must first be above 27' celsius. This reuslts in low pressure which gradually sucks the hot surface of the water body up to fuel the storm. As winds come together to force the hot water vapour up it cools and condenses to form cumulonimbus clouds. This process continues fuelled by the large body of water and the clouds and the storm continue to grow. As a reuslt of the coriolis effect, the storm begins to revolve and an eye may form in the centre of the storm. At the eye wind speeds are low and conditions are calm, but surrounding it, winds are reaching speeds of between 75 and 150km/h, pressure is extremely low and torrential rains pour down. If the storm moves towards land it may loose its energy source and die out however, before this happens it can cause large amounts of inland flooding and the destruction of infrastructure as was seen in the 2005 Hurricane Katrina in America which led to 800,000 homeless and cost around $160 billion to the US government.
