Following a week of extreme heat and dryness over southern Africa, parts of South Africa are in for a prolonged spell of widespread rainfall, heavy in places, the SA Weather Service warned.
Heavy rain is expected from Saturday over the Eastern Cape and KwaZulu-Natal and will spread to parts of the Free State, Gauteng, Mpumalanga, and Limpopo on Sunday.
The weather service has warned South Africans of a dramatic drop in daytime maximum temperatures over the eastern provinces, including Gauteng.
Much of the highveld can expect maximum temperatures in the low teens on Monday and Tuesday, with Johannesburg likely to peak at only about 11 to 12°C. Some high-lying areas may even see single digit maximum temperatures

“In addition, a significant lowering of the altitude at which sub-zero temperatures occur, commonly referred to as the ‘freezing level’, will most likely result in disruptive snowfall over the Drakensberg mountains and Van Reenens Pass on the N3 highway in KwaZulu-Natal on Sunday. Lighter snowfalls can be expected over higher peaks of adjoining provinces such as the Eastern Cape and extreme eastern Free State,” said the weather service.
“There is even a small, but distinct possibility of light snowfalls over the Roossenekal pass as well as the Belfast and Dullstroom areas of the Mpumalanga escarpment early next week.”
Cold, moist and windy conditions are expected over the Highveld from the east on Sunday, resulting in severe thunderstorms with large, damaging hail, heavy downpours and strong, damaging surface winds.
