Strategies that help to prepare for and manage the effects of tropical cyclones

Being prepared is essential to preventing loss of life and property when a Tropical Cyclone approaches.
First World countries are better prepared in this regard. Far more loss of life occurs in Third World countries due to less advanced warning systems and a lower level of preparedness.

The link below is a First World example of preparing communities for a Hurricane.
