Today, I've posted all survey qns on facebook and done some research, some of which may be of some help to marcus who is researching on evacuation plans. Research is as follows:

Hurricanes
Description
Tropical cyclones can produce extremely powerful winds and torrential rain, as well as high waves and damaging storm surge as well as spawning tornadoes. They develop over large areas of water, gathering heat and energy through contact with warm water and loses its strength as it moves over land. Although their effects may be deadly, such “disasters” also help relieve drought conditions.

The eye
A powerful cyclone will harbor an area of sinking air at the centre of circulation. If this area is strong enough, an “eye” will be developed. Surprisingly, weather in the eye is normally calm and free of clouds, though the sea may be extremely violent.

Evacuation/safety plans
If news report that a hurricane is approaching, this are some steps you can take. Lock all windows and bring in all outdoor equipment that can be blown away. Make sure you have a radio with you so you can listen to storm advisories. In most places, banks and ATMs are usually closed so have some cash in handy. If your house isn’t on a higher ground, go to a shelter. Lastly, DO not drink tap water until officials say its safe to do so.
