The South African Weather Service (SAWS) said flooding is expected in parts of the country, including the Northern and Eastern Cape, Free State, North West, Gauteng, KZN and the Highveld of Mpumalanga.
According to the weather service, the rains will be accompanied by cold to very conditions over the southern and southeastern interior of South Africa on Friday, which will spread to the central and eastern interior by Saturday.
City of Johannesburg EMS spokesperson, Robert Mulaudzi, said the weather service warned that the severe thunderstorms could lead to flash floods and extremely cold temperatures “in most parts.”
He urged Johannesburg residents to be safe and told motorists to avoid crossing flooded roads.
“Residents are also urged to use all heating devices safely not to leave them unattended to prevent fire incidents at home this weekend,” said the EMS spokesperson.
Joburg Disaster Management teams have been dispatched to all seven regions of the city, including the Swift Rescue Unit – a specialised team that responds to water-related emergencies.
Johannesburg residents are also urged to be extra cautious around water and churches are told to be careful while conducting baptisms as water levels are higher and dangerous, said Mulaudzi.
This warning follows an incident in Paulshof over the past weekend where a pastor and two of his congregants were trapped in a stream while conducting a baptism.
