Rain set to slam the south-west

Gale force winds topping 70km/h and high seas with waves rising above the seven-metre mark have been predicted for coastal areas, whereas the City of Cape Town itself could see the worst of the downpours and flooding. More than 50mm of rain is expected to land in the region over the next 48 hours.

But where will the rain fall hardest, and who will get the lion’s share of the deluge? We’ve got all the information mapped out for you here, including a quick look at how the latest Cape Town weather forecast will affect the depleted dams within the metropolitan area.

Latest Cape Town weather forecast for Wednesday 10 June

The first few spots of rain will land on Tuesday evening, before Wednesday brings the Mother City everything from booming thunderstorms to possible flash floods. The rain will fall steady in the early hours of the morning, but just after 4:00, it starts to pelt it down.

You can expect heavy showers across the entire western coast, with central and southern areas of the province also affected. The later stages of the morning – between 9:00 to 12:00 – promise to bring the most precipitation with them. Over a 24-hour period on Wednesday, 30-40mm could hit Cape Town, and up to 65mm of rainfall could douse the Cape Winelands over the course of a single day:
