Hurricanes and Haiti: A Tragic History
By Jeffrey Masters, Ph.D. — Director of Meteorology, Weather Underground, Inc.
In many ways, the hurricane season of 2008 was the cruelest ever experienced in Haiti. Four storms--Fay, Gustav, Hanna, and Ike--dumped heavy rains on the impoverished nation. The rugged hillsides, stripped bare of 98% of their forest cover thanks to deforestation, let flood waters rampage into large areas of the country. Particularly hard-hit was Gonaives, the fourth largest city. According to reliefweb.org, the rains from 2008's four storms killed 793, left 310 missing, injured 593, destroyed 22,702 homes, and damaged another 84,625. About 800,000 people were affected--8% of Haiti's total population. The flood wiped out 70% of Haiti's crops, resulting in dozens of deaths of children due to malnutrition in the months following the storms. Damage was estimated at over $1 billion, the costliest natural disaster in Haitian history. The damage amounted to over 5% of the country's $17 billion GDP, a staggering blow for a nation so poor.

The year 2008 was only one of many years hurricane have brought untold misery to Haiti. Hurricane Jeanne of 2004 passed just north of the country as a tropical storm, dumping 13 inches of rains on the nation's northern mountains. The resulting floods killed over 3000 people, mostly in the town of Gonaives. Jeanne ranks as the 12th deadliest hurricane of all time on the list of the 30 most deadly Atlantic hurricanes . Unfortunately for Haiti, its name appears several times on this list. Hurricane Flora killed over 8000 people in 1963, making it the 6th most deadly hurricane ever. An unnamed 1935 storm killed over 2000, and Hurricane Hazel killed over 1000 in 1954. More recently, Hurricane Gordon killed over 1000 Haitians in 1994, and in 1998, Hurricane Georges killed over 400 while destroying 80% of all the crops in the country.
Surprisingly, only six major Category 3 and stronger hurricanes have struck Haiti since 1851. The strongest hurricane to hit Haiti was Hurricane Cleo of 1964, which struck the southwestern peninsula as a Category 4 storm with 150 mph winds, killing 192 people. Haiti's only other Category 4 storm was Hurricane Flora of 1963, which had 145 mph winds when it struck the southwestern peninsula, killing 8000. No Category 5 hurricanes have hit Haiti since 1851. The most recent Category 3 hurricane to hit Haiti was Hurricane David of 1979, which crossed northern Haiti as a Category 3 hurricane with 115 mph winds after hitting the Dominican Republic as a Category 5 hurricane with 170 mph winds. David weakened quickly to a tropical storm after crossing into Haiti, as caused no deaths in the country. The other major hurricanes to strike Haiti were Hurricane Inez of 1966, which hit southern Haiti as a Category 3 hurricane with 115 mph winds, killing 480 people; Hurricane Katie of 1955, which hit near the Haiti/Dominican Republic border with 115 mph winds, killing 7; and Hurricane Five of 1873, which hit the southwestern peninsula with 115 mph winds.

Why does Haiti suffer a seemingly disproportionate number of flooding disasters? The answer in that in large part, these are not natural disasters--they are human-caused disasters. Haiti is the poorest nation in the Western Hemisphere. With oil too expensive for the impoverished nation, charcoal from burnt trees has provided 85% or more of the energy in Haiti for decades. As a result, Haiti's 8 million poor have relentlessly hunted and chopped down huge amounts of forest, leaving denuded mountain slopes that rainwater washes down unimpeded. Back in 1980, Haiti still had 25% of its forests, allowing the nation to withstand heavy rain events like 1979's Category 3 Hurricane David without loss of life. But as of 2004, only 1.4% of Haiti's forests remained. Jeanne and Gordon were not even hurricanes--merely strong tropical storms--when they stuck Haiti, but the almost total lack of tree cover contributed to the devastating floods that killed thousands. And it doesn't even take a tropical storm to devastate Haiti--in May of 2004, three days of heavy rains from a tropical disturbance dumped more than 18 inches of rain in the mountains, triggering floods that killed over 2600 people.
What can be done to reduce these human-worsened natural disasters? Education and poverty eradication are critical to improving things. In addition, reforestation efforts and promotion of alternative fuels are needed.
In the past two decades, the U.S. Agency for International Development has planted some 60 million trees, while an estimated 10 to 20 million of these are cut down each year, according to the USAID director in Haiti, David Adams. If you're looking for a promising way to make a charitable donation to help Haitian flood victims, considering sending a check to the Lambi Fund of Haiti, which is very active in promoting reforestation efforts, use of alternative fuels, and infrastructure improvements at a grass-roots level to help avert future flood disasters.
