On This Date: An F5 Tornado Roared Through An Iowa College
One state's earliest known most violent tornado carved through a town, including a college campus in an era decades before the first tornado warning was issued. On June 17, 1882, 143 years ago today, an F5 tornado tore an estimated 105-mile long path through parts of six central Iowa counties, claiming 68 lives and injuring another 300. According to the National Weather Service and tornado historian Thomas Grazulis, the twister killed 10 near the towns of Rippey, Kelley and southwest Marshal. County before it barreled into the town of Grinnell. At least 39 were killed and 73 homes destroyed in Grinnell, about 45 miles east-northeast of Des Moines. Both buildings of what was then known as Iowa College were destroyed, and three students were killed in their dorm rooms that day. Another 13 fatalities occurred southeast of Grinnell near Malcolm and Brooklyn, Iowa. Of the Hawkeye State's 11 known F5 or EF5 tornadoes, this was the earliest on record. It happened without warnings, as the first public tornado warning wasn't issued until 1952. It also happened over 100 years before the nation's Doppler radar network was built. This destructive tornado didn't spell the end for the college, though. Once news of the school's financial challenges after the tornado filtered through the press, and after one of the town's founders visited the Chicago Board of Trade, donations from across the nation allowed the school - now called Grinnell College - to rebuild.

On Today's Date: The Enigma Tornado Outbreak
Arguably one of the nation's worst tornado outbreaks still has many unknowns to this day, largely because it happened in the late 19th century. From Feb. 19-20, 1884, 141 years ago, a swarm of deadly tornadoes ripped through the Southeast from Mississippi and Kentucky to the Carolinas and Virginia. That much is certain. But it's called the "Enigma Outbreak" because there's no definitive count of the number of tornadoes or related deaths they caused. Tornado historian Thomas Grazulis listed 37 "strong tornadoes" in this outbreak across eight states, what would today earn at least an EF2 rating on the Enhanced Fujita scale. (This happened 36 years before the father of the scale, Tetsuya Fujita, was born.) Some accounts have at least 51 total tornadoes. In an era where weather forecasting was in its infancy without Doppler radar, radio or television, these outbreaks were far deadlier than today. At least 180 were killed in the South, but that's likely an underestimate, given that it hit in more rural, sparsely populated areas that may not have reported at the time. This outbreak would likely have been more of an unknown without the efforts of John Park Finley, whose pioneering efforts and detailed documentation of the outbreak laid the foundation for the future of tornado and severe thunderstorm forecasting in the 20th century.
