A hailstorm has battered Johannesburg, with several road accidents being reported.

Radio 702’s early morning show has been inundated with calls and SMSes from people reporting heavy hail and rain.

Several said road conditions were very poor and urged motorists to drive with extreme caution.

Presenter Ray White said he had heard of a fatal accident in Randfontein. A caller said she was stuck behind a three-car pile-up.

One man, calling from Rosebank, said: “It’s white, white, white.”

Another woman said that even though she was driving at 50km/h, her brakes were not working because of the slipperiness of the roads.

On Twitter at 5.57am, the SA Weather Service posted this warning: “Severe thunderstorm over N. Joburg and Centurion with possible heavy falls that might lead to road flooding within the next 30min.” - IOL
