The City of Johannesburg’s Emergency Management Services warned of a drop in temperatures from Wednesday.
They also urged people to be careful when using heaters.
A recent fire in the Kwa Mai Mai informal settlement killed one person and displaced 50 others.
A cold front is expected to hit Gauteng on Wednesday with minimum temperatures as low as zero degrees Celsius in Johannesburg.
City emergency services spokesman Robert Mulaudzi said, “We just want to urge all residents to exercise caution when using heaters. Do not leave them unattended to avoid house fires. Things like heaters, kerosene stoves, braziers and candles.
“The city’s disaster management teams will remain on high alert to monitor our vulnerable communities and informal settlements across the city, using our disaster management teams in all seven regions of the city,” adds Mulaudzi.

Meanwhile, Cape Town traffic authorities have closed Spine Road between the N2 highway and Faure Road as much of the carriageway collapsed due to persistent rain.
Traffic spokesman Kevin Jacobs said the left lane on the N2 entering Spine Road is flooded.
Jacobs says this results in significant traffic delays.
“Traffic officers are diverting motorists around the scene. Motorists are advised to exercise patience when traveling in this vicinity. We advise motorists to look for alternative routes,” he explains.
