The thick haze that cloaked downtown Chattanooga and some surrounding areas Friday came from controlled burns in nearby counties, according to the Hamilton County Air Pollution Control Bureau and Georgia Forestry Commission.
Two prescribed burns in North Georgia were the likely source of the smoke in downtown Chattanooga, according to Georgia forestry officials.
The larger of the two fires is a 3,800-acre burn between 1,700 and 3,200 feet of elevation in Noontootla, Ga., southeast of McCaysville, Ga. A second, smaller fire in Sugar Valley, Ga., near Ringgold, Ga., is about 1,000 acres between 900 and 1,200 feet, state officials said.
Pollution Control Bureau Director Bob Colby said the Tennessee Division of Forestry also was burning 170 acres of forest floor in Sequatchie County on Friday afternoon. And controlled burns started in Marion County on Thursday.
"This is an ideal time of year for foresters to burn off all the fuel on the forest floor," Colby said. "Hopefully when it gets a little clearer and less windy we won't be impacted by burns happening outside Hamilton County."
There are currently eight controlled, burns in East Tennessee, including one near Etowah and one southeast of Tellico Plains, according to meteorologist Terry Getz with the National Weather Service in Morristown, Tenn.
Weather conditions are causing the haze to concentrate in the area instead of dispersing, Getz said.
"When you have warmer air off the surface and light winds when they're doing these burns, the smoke from the fires doesn't get as dispersed," he said. "It seems like there are light winds below 5,000 feet, and that smoke may be drifting over by Chattanooga and getting trapped. The haze is probably smoke, pollutants from the prescribed burns from the controlled burns."
Getz says the National Weather Service hasn't received notifications of wildfires in the area.
