Georgia Severe Weather Preparedness Week
Although not widely known, flooding kills more people than any other weather hazard. The majority of deaths from flooding occur when people become trapped in automobiles that stall while driving through flooded areas. Nearly half of all flood fatalities are vehicle related. Flooding is usually divided into two categories. These categories are flash flooding and river flooding. Both of these can cause death, injury, and property destruction.
Flash floods are usually caused by slow moving thunderstorms or thunderstorms that move over the same area one after the other, called training. These floods usually occur within 6 hours of heavy rainfall and are usually more life threatening as a result. Areas most prone to floods are mountainous streams and rivers, urban areas, low-lying areas, and culverts. A good example of flash flooding is the flooding in metropolitan Atlanta in September of 2009.
River flooding is caused by the gradual increase in the water level of a river or creek. These floods usually occur seasonally with general rains or with heavy rainfall from tropical systems. A good example of river flooding is the flooding that affected south Georgia after Tropical Storm Alberto in 1994.
So, what can you do to protect yourself and your family?
