Snow is also expected in four provinces according to Snow Report SA, with the first light snowfall starting on Tuesday evening.

Watches have also been issued for heavy rain and localised flooding for the South Coast in Western Cape and western coastal parts of Eastern Cape. 

Severe thunderstorms are also expected in the Highveld areas of Mpumalanga and the eastern parts of Free State.

Cold snap

According to SAWS, a steep upper-air trough, having the potential to cut off and further intensify, will result in significantly cooler weather over most parts of the country on Wednesday into Thursday, with the expectation of snowfalls on some southern mountains.

Very cold conditions are expected over the northern interior of the Eastern Cape on Wednesday and Thursday, spreading to the southwestern high ground of KZN and extreme northeastern parts of the Free State on Thursday.

Snow in November

Snow Report SA has released an advanced forecast for the Western Cape, Eastern Cape, Free State, KZN as well as Lesotho for this week.

According to their forecast, snow will start falling in South Africa on Tuesday night in the eastern parts of the Western Cape and the Sneeuberge in the Eastern Cape. 

Ben Macdui in the Eastern Cape should expect 40cm of snow from Wednesday morning, while Thaban Ntlenyana in Lesotho should get almost 1m of snow. 

By Wednesday afternoon the snow should have spread to the Drakensberg range in the Eastern Cape and by the evening it should hit surrounding towns. Sani Pass could possibly get 50cm on Wednesday evening.

"At the same time, snowfalls will commence throughout most of Lesotho, and into some high lying areas around Kokstad and Matatielle, with light falls possible to come down into KZN around Underberg and Himeville, and possibly even towards Bulwer by Thursday morning," says Snow Report SA.

It is also possible that the Clarens area in the Free State will see snow on Thursday morning, as well as the Harrismith and Van Reenen region, though forecasters note this is only a possibility at this stage. Snow should stop falling by Thursday evening.
