To what extent can preparedness and planning mitigate the effects of tropical revolving storms? (40 marker)

A tropical revolving storm is a term that covers hurricanes, tropical cyclones, typhoons and willy-willies. These intense low-pressure weather systems are associated with catastrophic wind speeds averaging at 120kmph and torrential rainfall. Tropical revolving storms are huge and extremely violent extending to about 500km in diameter. They occur in the tropics and the sub-tropics and form over the oceans where sea surface temperatures are above 27’C.
Tropical storms are natural hazards, a natural event brought about by weather or climate that threatens life and property, and therefore cannot be prevented, however there are

Structural approaches may also be necessary to protect coastal areas. Preparedness includes the education of populations. People need to know the dangers and what they can do to avoid them. In Florida, evacuation routes have been prepared and cyclone shelters are clearly signed and posted. Planning includes land-use planning. This regulation is used to reduce the vulnerability of people and property so for example, only low value land uses (recreational) can occupy coastal strips, the areas most vulnerable to a storm. In Northeast Florida, coastal properties have been rallied above the ground on stilts and have non-residential functions on the ground (storage). This means that hazards like the storm surges do not impact the people and less damage occurs to infrastructure.
Warning systems put in place to predict incoming storms inform the public about them. This is linked with the effectiveness of the government and how developed the country is. A less developed country is less likely to have the money to be able to afford such technology and equipment meaning that no matter what form of planning or preparedness occurs, mitigation is less likely to be achieved. More developed countries have the money to install advanced technology and equipment to ensure that their population can be warned meaning that lives can be saved.

In late August 2005, Hurricane Katrina swept onto the coast of Louisiana with winds of over 160km per
