A chemical plant fire southeast of Atlanta is still causing trouble two days later. Authorities on Tuesday alerted residents of the city's eastern suburbs to shelter in place again if a chemical cloud moves over their neighborhood.

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.
