Gauteng residents have been urged to brace for more heavy rains, flash flooding and fierce thunderstorms.
The Gauteng Provincial Disaster Management Centre issued the warning on Friday, saying the developing of the La Nia system was intensifying, bringing unpredictable and fast-moving storms.
The South African Weather Service has also issued multiple severe weather alerts, including a Level 4 warning for parts of Limpopo and Level 2 alerts for the Free State, North West and Eastern Cape, due to heavy downpours, localised flooding, strong winds and small hail.
