DETROIT, Oct. 20 (UPI) -- Parts of Detroit were blanketed Monday with thick smoke from a tire fire in nearby River Rouge, Mich., authorities said.
Billows of soot floated along Interstate 75 at the River Rouge bridge and into the Rosa Parks Boulevard area of Detroit, city fire Capt. Steve Varnas said.
"When that cools enough to settle, there's going to be black soot covering stuff," Varnas said, describing the smoke as heavy in carbon and, therefore, a serious health risk.
Residents in the smokiest areas were advised to remain indoors until the fire was fully contained, Varnas told the Detroit Free Press in a story published Tuesday.
The fire looked ominous but was being brought under control and there was no need to evacuate, a River Rouge police spokeswoman said.
