Since 1985, the South Florida Metropolitan area (SFMA), which covers the counties of Miami-Dade, Broward, and
Palm Beach, has been directly affected by 9 tropical cyclones: four tropical storms and 5 hurricanes. This
continuous hurricane and tropical storm activity has awakened the conscience of the communities, government,
and private sector, about the social vulnerability, in terms of age, gender, ethnicity, and others. Several factors
have also been significant enough to affect the vulnerability of the South Florida Metropolitan area, like its
geographic location which is at the western part of the Atlantic hurricane track, with a surface area of 6,137 square
miles, and elevation of 15 feet. And second, from the 2006 Census estimate, this metropolitan area is the 7th
most populous area in the United States supporting almost 1,571 individuals per square mile.
Mortality levels due to hurricanes and tropical storms have fluctuated over the last 21 years without any signal
of a complete reduction, a phenomenon that can be related to both physical characteristics of the storms and
government actions. The average annual death count remains almost the same from 4.10 between 1985 and
1995 to 4 from 1996 to 2006. However, the probability of occurrence of a direct impact of an atmospheric
disturbance has increase from 0.3 to 0.6, with an average of three hurricane or tropical storm direct impacts for
every five. This analysis suggests an increasing problem with regard to atmospheric disturbances-related deaths
in the South Florida Metropolitan area. In other words, despite substantial increases in population during the last
21 years, the number of tropical cyclone-related deaths is not declining; it's just being
segregated among more storms.
Gaps between each impact can be related to mortality levels. When that time increases in five years or more,
such as Bob and Andrew or Irene and Katrina, or decreases in weeks or months, such as Harvey and Irene or
Katrina and Wilma, mortality also increases. A relief is also remarkable when that time is between one and four
years, which might be related to better government actions during a certain period after a strong hurricane impact.
Results reflect a lack of focus on hurricane and tropical storm related themes, while a decrease in funding can
be the consequence of less interest and much more attention on less probable hazards with a long term recovery
period. Even though the government has an important role in hurricanes and tropical storms mitigation, some of
the main ideas to decrease mortality are focused in networking between private and public sector and the
understanding of self-vulnerability of each individual.
