An alarming number of fatalities in recent years has led to Tennessee being dubbed part of Killer Tornado Alley.“We all think of Tornado Alley as part of the Midwest and Great Plains because that’s where historically most tornados have occurred,” said National Weather Service meteorologist Mark Rose during his address Thursday to McMinnville’s Noon Rotary Club. “While that may still be true, we are seeing a high number of fatalities in what we are calling Killer Tornado Alley, which includes part of Tennessee.”The epicenter of Killer Tornado Alley is in southeastern Tennessee, northern Alabama and Mississippi. A secondary alley radiates out and encompasses part of Middle Tennessee.
