The Great Tri-State TornadoMarch 18th, 2013 at 7:30 pm by Bill Steffen under Bill's Blog, Weather
Today (Monday, March 18) is the anniversary of the worst tornado in U.S. history (in 1925). It set records for longest tornado on the ground (219 miles) , most fatalities (695), fastest forward speed (average 56 mph, nearly 75 mph at the beginning). The twister crossed the Mississippi River about 75 miles southeast of St. Louis, moving from Missouri, across southern Illinois and into Indiana. The tornado followed a railroad line, destroying towns (four towns were completely destroyed) that had sprung up along the railroad. The twister averaged 3/4-mile wide and at times was over a mile wide. Survivors described the approaching storm as a rolling, boiling fog. Fires set by the tornado could be seen 60 miles from the tornado’s path.
A few years ago, my wife and I drove along the path of this storm and stopped at libraries and city halls to see what I could learn. At a mine, the entire above ground structures were destroyed, trapping miners underground (they were later rescued. Nine schools were destroyed and 69 children lost their lives that day. There were 2027 recorded injures (not counting those who were not counted at overcrowded hospitals). Fifteen thousand homes were destroyed. The twister occurred before the F-scale for rating tornadoes was established, but there is agreement that this one was an F5. Seven other tornadoes caused fatalities that day, another 52 total in tornadoes that occurred in northern Alabama, Tennessee, Kentucky and southern Indiana. Thorough new and continuing research has found no break in the path and also that the tornado touchdown may have occurred approximately 15 miles before previously thought, bringing the total path length to around 234 mi. Damage from the tornado totaled nearly 17 million dollars, which adjusted for inflation would be close to 2 billion dollars today.
Also, check out the squall line of storms moving thru Alabama and Georgia this Monday evening. Six injuries at Seney, GA. They’ve had softball-sized hail and gusts over 75 mph with these storms.
