The destruction caused by hurricanes in the Caribbean and Central America is a force that has shaped history and will shape the future of the region. The danger arises from a combination of factors that characterize tropical cyclonic storms: rise in sea level, violent winds, and heavy rainfall. In the Greater Caribbean Basin from 1960 through 1988 (excluding the United States and U.S. territories) hurricanes caused more than 20,000 deaths, affected 6 million people, and destroyed property worth over US$9.5 billion (OFDA, 1989). The great bulk of this harm was done to the Caribbean island countries, whose small economies are least able to withstand such impacts.
Data on hurricane damage have been collected since the discovery of the Americas, and recent statistics show that mitigation measures have made a difference since the 1930s. While the ferocity of the storms has not abated over the years, and population has increased substantially in the area, the casualty rate has decreased as a result of the incorporation of mitigation measures and the increased effectiveness of preparedness activities. This improvement in saving lives has been countered by a marked increase in property damage. This is a clear indicator that structural mitigation measures are not keeping pace with the rapid increase in development in vulnerable areas.
A important feature of this chapter is its detailed discussion of hurricane hazard mitigation in small towns and villages. In this setting, largely beyond the reach of national mitigation activities, simple strategies are both essential and highly effective.

"Tropical cyclone" is the scientific term for a closed meteorological circulation that develops over tropical waters. These large-scale non-frontal low-pressure systems occur throughout the world over zones referred to as "tropical cyclone basins" (NOAA, 1987). The name for them varies: in the Atlantic and northeast Pacific they are called "hurricanes" after the Mayan word for devil, in the northwest Pacific "typhoons," and in the South Pacific and Indian Ocean simply "cyclones." Of all tropical cyclone occurrences, 75 percent develop in the northern hemisphere, and of these, only one out of three are hurricanes in the northeast Pacific or northwest Atlantic (UNDRO, 1978). The storms of the northern hemisphere travel westward; those of the southern hemisphere move eastward.
In the Atlantic tropical cyclone basin, which includes the Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico, hurricanes originate mostly in the northern Atlantic and to a lesser degree in the Caribbean. The areas most at risk are the Caribbean island countries north of Trinidad (73 strikes by major hurricanes between 1900 and 1988), Mexico and the southeastern United States, Central America north of Panama, and to a limited extent the northern coast of South America (Tomblin, 1979). Hurricanes also originate in the northeast Pacific, where they can affect the west coast of Mexico. Most of South America is essentially at no risk, because the tropical southwestern Atlantic and the southeastern Pacific are devoid of these meteorological occurrences, but systems originating on the west coast of Africa can potentially strike the northernmost part of the continent; for example, in 1988 Hurricane Joan formed on the northwestern coast of Africa and struck the coast of Venezuela and Colombia before hitting eastern Nicaragua.
