The National Weather Service says a single, multi-vortex tornado plowed through 49 miles of southern Indiana and northern Kentucky, killing 10 people along its path through New Pekin, Henryville, Marysville and Chelsea before it crossed the Ohio River near Bedford, Ky.
The weather service office in Louisville, Ky., on Tuesday completed posting its survey results online from the supercell that spawned the tornado that first touched down near Fredericksburg, Ind., about 30 miles northwest of Louisville, and finally ended 49 minutes later north of Bedford, about 35 miles northeast of Louisville.
It killed a family of five in a mobile home in the New Pekin area, a man near Henryville and four other people near Chelsea. At its greatest strength it rated EF4 and packed winds of 175 mph.
