Monday's driving rain and cold wind are just a taste of what is to come, with snow predicted for the mountains of the Western Cape, the higher ground of the Eastern Cape, and the southern heights of the Northern Cape on Tuesday.
The SA Weather Service warned that there would be more snow and gale force winds on Tuesday morning - and, for those at sea, there would be high seas.
"The first cold front for the winter made landfall early this morning in Cape Town," said James-Brent Styan, spokesperson for Anton Bredell, the MEC for local government in the Western Cape.
"It has brought stormy, cold and wet weather, reinforced by gale force winds across large parts of the province," he said.
"We're happy to see some wet weather in the Western Cape because it means our dam levels will get a much-needed boost.
