The hurricanes have very negative effect in the Central Americana and Caribbean regions.
Explanation:
The hurricanes are some of the most dangerous natural hazards in the world. They form usually in the warm waters between South America and North America, or rather in the Caribbean region. The strong winds and enormous amounts of rainfall have varying effects, depending on the place, and depending on the type of the place that has been hit by them.
The Caribbean and Central American regions are mostly consisted of poor, developing countries. The infrastructure is of bad quality, the organization levels are low, and the warning systems for dangers are often not functional or notify the people too late. This all results in tragedies when stronger hurricanes hit these regions, with the people having no time to escape because they have been notified too late, or not notified at all. The majority of the houses and other infrastructure gets totally destroyed, and the bad organization often lives the people on their own.
The results of this unfortunately are thousands of dead, badly injured, homeless, lack of food, lack of freshwater, and enormous material damage. This can easily be seen in the likes of:
- Dominican Republic
- Haiti
- Belize
- Guatemala
