  Countywide, Shelby County

  2 injured

  What happened

  Rainfall estimated as high as 6 inches caused widespread flash flooding across the area. Numerous roads became impassable as nearly every creek and small stream flooded. Two men suffered minor injuries near Hurdland in Knox County when they drove their truck into a flooded road. Another man had to be rescued after he was swept down a slough along Route K near Colony. Near Newark, 2 men drove into high water, abandoned their vehicle, but did not notify any official source. The 2 were issued summonses for not reporting the incident, as rescue attempts were made on the submerged vehicle. In Edina, the Farm & Home store was flooded with virtually the entire inventory destroyed. In Knox County, Routes 11 and 151, and County Roads C, J, F, V, K, M, TT were all closed.
