Tornadoes — not straight-line winds or powerful downdrafts called microbursts — struck the region on the night of April 28-29, according to on-the-ground surveys by National Weather Service experts. The overnight storms caused two deaths and destroyed a number of homes and buildings in Tennessee and Alabama.
"We look at patterns of debris and damage. Trees, if they're lying in different directions, that's one indication," said senior meteorologist Andy Kula of the Weather Service's Huntsville, Ala., office.
The strongest tornado was one in Lincoln County, Tenn., that claimed the lives of husband and wife John and Karen Prince, who died when their mobile home was blown away south of Fayetteville.
That tornado had a peak wind speed of 160 mph, which ranks as 3 on the Enhanced Fujita (EF) scale, the weather service determined. Its path was 500 yards wide and 20 miles long.
The second-strongest twister in the region was a 155 mph EF3 tornado that carved a path up to 600 yards wide through nine miles of Etowah and DeKalb counties in Alabama, destroying homes in places such as the Aroney community near Boaz.
The closest tornado to Chattanooga was an EF1 storm with a maximum wind speed of 105 mph that touched down just east of Cohutta, Ga., and tracked for a half mile into southern Bradley County, Tenn., along Hughes Lake Road, where a home was damaged.
"There was a house that was shifted off of its foundation," said Sam Roberts, a meteorologist with the Weather Service's Morristown, Tenn. office.
