The weather service warned of heavy downpours, strong damaging winds, hail, and excessive lightning, resulting in flooding and possible damage to settlements and infrastructure.
Gauteng
Damaging winds could damage settlements, disrupt beachfront activities and make navigation difficult in the Nelson Mandela Bay, Buffalo City, Ndlambe, Nqgushwa and Sunday’s River Valley Municipalities in the Eastern Cape.
Gauteng will be cloudy and cold with scattered showers and thundershowers.

Residents have been urged to avoid crossing flooded roads and bridges, and to seek shelter during thunderstorms.
Motorists have been urged to reduce speed, take extra care, keep their headlights on, and maintain following distances.

“Our specialised rescue unit remains ready to respond to any water-related emergencies. Motorists and pedestrians are asked to exercise caution, avoid flooded areas, and seek shelter during thunderstorms.
