Residents near Atlanta were asked again to shelter in place if a chemical cloud moved over their neighborhood as plumes from a chemical plant fire continued to shift overnight.

A weekend chemical plant fire that sent a massive plume of dark smoke into the Georgia sky has led to complaints about a strong chemical smell and haze several miles away across metro Atlanta

A small fire on the plant’s roof was initially contained but reignited Sunday afternoon, authorities said. More than 90,000 residents east of Atlanta were told to keep sheltering in place Monday a day after a chemical plant fire sent a massive plume of dark smoke high into the sky that could been seen for miles.
