2010 Billion-Dollar Weather Disasters
by Chris Dolcy, meteorologist, The Weather Channel
Since 1980, a total of 99 weather-related disasters have resulted in damages and costs reaching or exceeding $1 billion.
In 2010, three weather events were added to this exclusive list, which is compiled by the National Oceanic and Atmospheric Administration (NOAA).
The map below shows the number of these disasters that have occurred in each state since 1980. Keep in mind, a single billion-dollar disaster can include multiple states.
So, why does the South have the greatest concentration of these disasters? I'll give you one hint: it's related to the Gulf of Mexico and the Atlantic.
If you guessed tropical storms and hurricanes, then you are correct. In fact, they account for 27 of the 99 billion-dollar weather disasters since 1980.
