Rainfall is expected over most of South Africa on Wednesday, 12 April. The South African Weather Service has forecast a 60% chance of rainfall across central Mpumalanga, from Ermelo to Nelspruit, as well as the south-eastern parts of Limpopo near Polokwane.

A 30% chance of rain has also been forecast along the Garden Route from George in the Western Cape, moving upwards towards Calvinia in the Northern Cape.

Cape Town to Worcester can also expect a 30% chance of rain. The City of Cape Town has warned that its dam levels are effectively at 15,2%. Consumption over the past week has been 742 million litres per day, which is 42 million litres above the collective usage target of 700 million litres per day in the province.  

Reduction of water pressure in the Western Cape

As of Monday, 10 April, the city began reduction of water pressure in certain areas including "Blackheath, Kleinvlei, Kuils River, Delft, Macassar, Firgrove, Somerset West, Strand, Gordon’s Bay, and Sir Lowry’s Pass Village in an effort to reduce water losses through leakage in pipework." 

"It will take a number of consecutive winters of good rainfall for our dam levels to recover – and there is no guarantee that we will have above average rainfall in the coming winter."
