For those of you with hatches in the Mother City, this is the perfect time to batten them down. A two-day torrent of rain is set to batter the south-west, according to the latest Cape Town weather projections from both the South African Weather Service (Saws) and Ventusky.

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:

Thunderstorms will persist through the night, as the rain continues to pound the Cape. A persistent, slighty eased blanket of rain will cover the region for a second consecutive day, finally losing its potency towards the end of Thursday evening. The 48-hour cumulative forecast suggests that areas near Ceres, Somerset West and Paarl could have 100mm of rain between now and Friday.
Will the rainfall reach the dams?
Voelvlei, based in Tulbagh, and both Steenbras facilities near Grabouw could get upwards of 70mm over the next couple of days. Meanwhile, a more modest amount of 20-30mm will fall over Theewaterskloof and the Berg River dam, based near the Franschhoek / Villiersdorp region.
