Johannesburg is bracing for another round of heavy thunderstorms this Friday, with the South African Weather Service (SAWS) warning that severe weather conditions could intensify before easing.
After Thursday’s chaos of flash floods and gridlocked traffic, the city remains on high alert, with emergency services mobilised across flood-prone areas.
Flash Floods Leave Trail of Damage
Thursday’s downpours left parts of Gauteng soaked and struggling. Roads turned into rivers, cars were submerged, and residents in low-lying areas battled rising water levels.
Among the worst-hit areas were Alberton, Bedfordview, Crown Mines, Buccleuch, Primrose, and Sunninghill, where rescue teams worked through the night to assist stranded motorists and families whose homes were flooded.
City on High Alert
Johannesburg Emergency Management Services (EMS) spokesperson Robert Mulaudzi said the city is maintaining a “high alert” status as more storms approach.
“We’re monitoring all areas, especially informal settlements and flood-prone zones,” said Mulaudzi. “Our rescue units are ready to respond to any flash flood incidents.”
He urged motorists to avoid crossing flooded roads and to drive cautiously.
“It only takes a small amount of moving water to sweep a car off the road. Please don’t take the risk,” he warned.
Climate Concerns Rising
While summer storms are a familiar feature of life in Johannesburg, experts say they’re becoming more frequent and intense due to climate change and poor drainage infrastructure. Blocked stormwater systems and unchecked urban development are worsening flood risks across the city.
Wider Weather Warnings
The storm system is not limited to Gauteng. SAWS has also issued thunderstorm alerts for the North West, Mpumalanga, Northern Cape, and Free State.
Meanwhile, the Western Cape is facing a yellow-level 1 heatwave warning, with temperatures soaring in Matzikama and Bergrivier until Sunday.
Residents Urged to Stay Safe
Authorities are urging residents to remain vigilant and take precautionary measures:
-
Avoid crossing flooded bridges and low-lying areas.
-
Unplug electrical appliances during lightning activity.
-
Keep emergency numbers close.
-
Move to higher ground if floodwaters rise nearby.
Despite a touch of humour flooding social media — with memes of floating taxis and soaked commuters circulating widely — the mood across Joburg remains cautious.
As Mulaudzi reminded residents:
“The best protection is prevention. Stay alert, stay indoors if possible, and never underestimate the power of water.”
