Authorities on Tuesday alerted residents of Atlanta's eastern suburbs to shelter in place again if a chemical cloud moves over their neighborhood.

A weekend 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, where some schools canceled outdoor activities and residents living near the fire sheltered at home.

A shelter-in-place order had just been lifted Monday for more than 90,000 residents after a fire sent a massive plume of dark smoke into the sky Sunday.
