Hailstorm and heavy rains have hit parts of Johannesburg, causing flooding and damage to property, no injuries reported.

Johannesburg emergency services spokesperson, Robert Mulaudzi, says they will remain on high alert overnight.

"The hailstorm has been reported in areas like Pualshof, Rosebank, Sandton, along the N1 highway, and also in Midrand. So far, we don't have any injuries that have been reported. However, as emergency services, we remain on high alert overnight to make sure we can respond to all incidents that might be reported overnight."

In Midrand, several cars lost their windscreens when hailstones as big as golf balls pounded unsheltered vehicles.

"We urge motorists to exercise caution while driving and residents in low-lying areas, especially in informal settlements, to avoid crossing rivers or streams and keep children away from those areas so we can prevent further incidents which might occur throughout the day," Mulaudzi said.

Forecaster Jacqueline Modika said the service had issued a yellow level 2 warning.

"Thunderstorms, by nature, are accompanied by hail, lightning, heavy rainfall, and strong winds over a short period of time," she said.
