The South African Weather Service (SAWS) said windy and stormy conditions would be likely over parts of the country from Wednesday, 29 September, until Saturday, 2 October. Communities in southern KwaZulu-Natal and the Eastern Cape are expected to be most affected by the change in weather.
The weather service said accumulated rainfall may result in localised flooding in KZN, the Wild Coast and adjacent inland areas of the Eastern Cape from Wednesday. This comes after a two-week rainfall recess over the central interior of the country, which ended on Tuesday.
“Apart from the interior of the Western Cape, the western parts of the Northern Cape and the central and eastern parts of Limpopo where no rainfall is forecast at this stage, citizens across other parts of the country could experience scattered (60%) to isolated (30%) showers and thundershowers,” said SAWS in a media statement on Tuesday, 28 September.
“Furthermore, strong winds may affect some poorly anchored informal settlements over the central areas of the country (northern Free State, North West and eastern areas of the Northern Cape).”

The weather service expects rainy and cooler weather conditions to last over parts of the Eastern Cape, KZN and the south coast and adjacent interior of the Western Cape from Wednesday to Friday. This weather is also expected to spread to the central and eastern interior of South Africa on Thursday.
“Minor localized flooding is possible in the Thabo Mofutsanyane municipality and the eastern areas of the Gariep District municipalities of the Free State, Alfred Nzo, OR Tambo, Joe Gqabi and Chris Hani District municipalities of the Eastern Cape, and in places over the southern parts of KwaZulu-Natal (Ethekwini Metro, Ugu, Harry Gwala, Umgungundlovu and Ilembe District Municipalities) on Wednesday and Thursday,” said SAWS.
Meanwhile, severe thunderstorms with hail and strong winds are a possibility over the eastern half of the Northern Cape and the western halves of both the Free State and North West on Thursday afternoon.
SAWS said the anticipated change in weather conditions is because a “well-defined and slow-moving” upper-air trough developed.
