Some weather forecasters have suggested Tornado Alley, a swath through the Great Plains and Midwest that has seemed most prone to tornadoes, has shifted eastward to bring the killer tornadoes seen in the Chattanooga region this year.
But Greg Carbin, warning coordination meteorologist with the National Weather Service, says that is just too narrow a view.
Carbin says the alley really is a long L that for years has stretched into the Southeast.
But the tornadoes that mauled the Southeast six months ago were the super outbreak of all time.
Carbin said much more research is needed on the outbreak and the devastation it caused, but one thing is a pretty sure bet.
