The SA Weather Service (SAWS) predict heavy rain in some areas in SA.

"Cold to cooler, rainy and overcast conditions are expected to set in over the western parts of Northern Cape and Western Cape as well as the Eastern Cape, clearing partially from the west by Sunday, while KwaZulu-Natal will remain overcast until Monday."

"Scattered to widespread showers and thundershowers [are expected] over the eastern parts of Eastern Cape, KwaZulu-Natal, eastern Free State, North-West province, Gauteng, Mpumalanga, as well as the Limpopo province. Heavy rain leading to flooding is expected on Sunday in places over KwaZulu-Natal, the eastern parts of Mpumalanga and the Limpopo Province."

The agency also warns that the rains may "surpass the infiltration capacity of the ground, thus leading to overland runoff".

"Such runoff feeds into stream and river systems and often leads to river-flooding scenarios. The public should therefore remain vigilant and aware of the danger of localised urban flooding, particularly in low-lying areas and especially where the environment is modified by tarred roads and brick or concrete paving.

"Moreover, under such circumstances, the public are strongly discouraged from crossing low-water bridges, either on foot or in vehicles. In both cases there is the very real danger of being swept off the bridge, due to the extreme lateral force of floodwaters."

Scattered showers will be spread out through the rest of the country, except for the Northern Cape and the West Coast in Western Cape.
