Maps: Where the Tornadoes Struck, Destroying Buildings and Homes

Dozens of people were killed as tornadoes swept across at least six states Friday night and early Saturday morning.

In Mayfield, Ky., one of the hardest-hit areas, a tornado tore through a candle factory southwest of town, ripped the clock tower off the county courthouse, and caused widespread damage. Despite initial fears of a death toll in the dozens at the candle factory, company officials said Sunday evening that eight people were dead and more than 90 employees had been accounted for.

The buildings highlighted below in red appeared to have been destroyed or damaged, based on an analysis of aerial images of Mayfield’s downtown area. The level of damage sustained by the remaining structures was unclear.

There were also six confirmed fatalities in Edwardsville, Ill., where the roof of an Amazon warehouse partially collapsed. In Bowling Green, Ky., a tornado reached wind speeds of 150 miles per hour and severely damaged homes and businesses. Officials in Arkansas said that at least two people were killed in the state. A 94-year-old died at a nursing home in Monette, Ark., and another person was killed at a Dollar General store in nearby Leachville.

The tornadoes were part of a weather system that was wreaking havoc in many parts of the country and hit Arkansas, Illinois, Kentucky, Mississippi, Missouri and Tennessee. In Kentucky, one tornado stayed on the ground for more than 200 miles.
