Which Is More Dangerous, Dixie Alley Or New Madrid?

      I have decided to bypass another post on the New Madrid Fault just for the time being. The fault is still rumbling though. But the onslaught of severe and violent storms is taking center stage.  We hear about Tornado Alley all the time!

 

There is no doubt that more tornadoes occur in this alley/region compared to any other alley/region in the United States… However, there is another alley where some of the strongest long tracked tornadoes of all time have occurred… This alley is called Dixie Alley and I'm here to say it's very real and very dangerous! And we live smack dab in it.

      Richard Okulski, warning coordination meteorologist for the National Weather Service in Memphis, agreed. "There is an area from western Kentucky to northern Mississippi which is quite vulnerable to tornadoes," he said. "The area has been dubbed 'Dixie Alley.' This area has a longer severe weather season (November to May) and nocturnal tornadoes (10 p.m. to 6 a.m.) are common." Okulski said many homes in this area do not have basements or safe rooms to protect occupants. Not only have the frequency of tornadoes in Dixie Alley began to rival Tornado Alley, but the amount of destruction is staggering.

      Over the past three decades, tornadoes in this region have been responsible for roughly thirty deaths per year, far outpacing Tornado Alley mortality rates. Cataclysmic events such as the 2008 Super Tuesday tornado outbreak (87 tornadoes, 57 killed, three were in Muhlenberg County Ky.) and the tornadic outbreaks of April 2011 (541 tornadoes, 362 killed) characterize the raw natural power and lethality of Dixie Alley. Your local National Weather Service Agency releases Tornado Watches/Warnings to inform citizens of potential or imminent risk. The goal is to prevent destruction of life and property as quickly and effectively as possible. These warnings have become increasingly successful with the growth of the internet and data distribution. The NWS has preferred to take an over-cautionary approach when informing residents. On average, warnings result in false alarms 75% of the time but those numbers are decreasing. Often, local tornado sirens will be triggered without a confirmed visual at all, but the potential risk is enough to release a warning. The fundamental challenge to verifying a tornado touch down is that it must be done on-site, either by ground or aerial observation.

      That is why many counties in Kentucky have created organized Storm Spotter groups. The volunteers in these groups are highly trained and have experience in Dixie Alley spotting and are important in getting timely information to the National Weather Service. These individuals have become quite good at what they do. Tornadoes are difficult to see at night, even by trained spotters. Limited ground visibility from tree density and hilly, shifting roadways make ground observation as logistically challenging as it is dangerous. Down here in the Southeast we've got a lot more trees, so it makes them harder to see. Many of our tornadoes pop up at night, when most people are in bed. Because most people are in bed and possibly asleep, they miss the warnings of the approaching tornadoes. Just about anyone living in Dixie Alley for any length of time can tell you that the sound of tornado sirens wailing or Weather Radios screeching in the middle of the night is enough to either frighten or frustrate nearly everyone. It’s very likely that severe, tornadic storms will continue to increase in frequency and potency, continuing the trend seen in recent years in Dixie Alley.
