Rescuers made the grim discovery of a woman and the mangled remains of her car in the Umbilo River near Sarnia, west of Durban, on Friday.
This followed heavy rainfall in KwaZulu-Natal on Thursday which lead to several roads being flooded, including in Kloof, Hillcrest, Springfield, Reservoir Hills, Isipingo, Verulam and Tinley Manor.
Garrith Jamieson of ALS Paramedics said rescue teams resumed at first light on Friday after having to stop a search for the missing car, with a single occupant believed to have washed away, on Thursday night because of the danger of the raging river and dark conditions..
He said the vehicle was located just under a bridge in Gordon Road, off Stapleton Road, at about 2am.
