The City of Johannesburg Emergency Management Services (EMS) has urged residents and motorists to exercise caution following severe thunderstorms across the city.
EMS said no major incidents had been reported across Johannesburg so far.
Motorists have been advised to drive carefully, maintain a safe following distance and avoid attempting to cross flooded roads or low-lying bridges.
Residents in low-lying areas have also been urged to remain vigilant and avoid crossing rivers and streams because of the risk of drowning.
The warning also extends to faith-based organisations, which have been urged to avoid visiting rivers and streams to conduct baptisms or cleansing rituals during the severe weather conditions.
EMS said its rescuers, together with the Aquatic Rescue Unit, would remain on high alert overnight while monitoring all seven regions of the city for possible emergencies.
Residents are encouraged to contact the Emergency Management Services Command and Control Centre on 011 375 5911 in the event of a life-threatening emergency.
The City has reiterated the importance of following safety precautions while severe weather conditions persist.
