CONYERS, Ga. — Editor's note: This live blog is no longer being updated; for Thursday's updates, head here.
A chemical cloud continues to loom over Conyers following a fire at a BioLab facility on Sunday.
The most recent shelter-in-place guidance advises people to stay indoors at night, from 7 p.m. to 7 a.m., when conditions are worse. This is to last through Friday. 11Alive Meteorologist Melissa Nord explains here why conditions are worse at night.
Georgia's Emergency Management Agency/Homeland Security (GEMA) overnight chlorine levels at the BioLab site where the plume is emanating from went above the "action level" at some points.
"Overnight, monitoring around the Bio Lab facility detected some exceedances above the action level for chlorine. Workers on site have continued to make progress in neutralizing the product. As the neutralization process continues, periodic increases in chlorine levels around the facility are expected," a release said.
An action level is, according to the EPA, "the concentration of a contaminant which, if exceeded, triggers treatment actions or other requirements."
Both GEMA and Atlanta-Fulton County EMA say wind shifts are expected to bring the chlorine smell and haze west toward Atlanta by Thursday morning, with Atlanta-Fulton County EMA saying this could last "several days" possibly through Sunday.
A shelter-in-place advisory was lifted Monday evening before the county changed course hours later early Tuesday morning and re-issued an advisory specifically for those who see the plume directly in their area, after increased reports of symptoms related to the chlorine smell and haze in the area.
"During certain times, due to weather and inversion in the evening, air quality readings may dip to concerning levels for those in direct exposure to the plume," Rockdale County said.
A Georgia Poison Center hotline has been set up at 404-856-6252 for anyone wishing to report symptoms such as nose, throat or eye irritation or difficulty breathing.

7:54 p.m. | Rockdale County officials are addressing concerns about the plume and the change in color. A fire did not restart. Officials said the increased volume of plume and changes in color are not from a fire but from the process of cleaning up the debris. There is a product under the building debris that is being disturbed during the cleanup process. Until the cleanup is done, there will be fluctuations in the plume.

2:00 p.m. | Now the Atlanta-Fulton County EMA has put out a release concurring with the earlier GEMA information about a wind shift bringing the chlorine smell and haze westward (i.e. toward Atlanta) by tomorrow morning.
Atlanta-Fulton County EMA adds a new detail, however, saying this could last "several days, possibly through Sunday, October 6."
The agency said:
At this time, chlorine levels in the air are at safe levels and there are no active advisories in place in Fulton County. Rockdale County Emergency Management Agency has issued a shelter-in-place advisory that applies within in Rockdale County.
While wind patterns this week have been primarily in an easterly direction, weather forecasts show that winds are expected to shift in a westerly direction starting Wednesday night. This shift in wind patterns may increase the presence of smoke and airborne chlorine in Fulton County and other parts of the state located west of Rockdale County.
It is predicted that haze and chlorine smell will be most noticeable in parts of Fulton County in the morning hours starting on Thursday, October 3. This pattern may last for several days, possibly through Sunday, October 6.
Fire departments across Fulton County are continuing air quality monitoring. AFCEMA is coordinating with these agencies.
12:20 p.m. | Georgia's Emergency Management Agency/Homeland Security (GEMA) issued some new information about the plume Wednesday afternoon.
It says overnight chlorine levels at the BioLab site where the plume is emanating from went above the "action level" at some points.
"Overnight, monitoring around the Bio Lab facility detected some exceedances above the action level for chlorine. Workers on site have continued to make progress in neutralizing the product. As the neutralization process continues, periodic increases in chlorine levels around the facility are expected," a release said.
This comes as GEMA also said "current weather models show the winds will begin to shift from the east to the west after sunset Wednesday." That would push it more toward the City of Atlanta.
"Smoke is predicted to settle towards the ground as it moves toward Atlanta. There is a high likelihood that people across Metro Atlanta will wake up on Thursday morning seeing haze and smelling chlorine," the release stated.
GEMA additionally says officials will have a device called a Trace Atmospheric Gas Analyzer on hand to monitor levels. It is described as a "self-contained mobile laboratory capable of real-time monitoring of outdoor air or emissions."
