1974: A “Super-Outbreak” of tornadoes ravaged the Midwest and the Eastern U.S. Severe weather erupted early in the afternoon and continued through the next day. Severe thunderstorms spawned 148 tornadoes from Alabama to Michigan, most of which occurred between 1 PM (CST) on the 3rd and 1 AM on the 4th. The tornadoes killed 315 persons, injured 5300 others, and caused 600 million dollars damage. Alabama, Kentucky, and Ohio were especially hard hit by the tornado outbreak. One tornado destroyed half of the town of Xenia, Ohio killing 34 persons. Another tornado, near the city of Stamping Ground, Kentucky produced a path of destruction a record five miles in width. A tornado raced through Guin, Alabama at a speed of 75 mph. Two powerful tornadoes roared across northern Alabama during the early evening hours, killing fifty persons and injuring 500 others.
