Cape Town - The South African Weather Service has warned of disruptive weekend snowfall over mountain passes in the South, Central and North Eastern parts of the Western and Eastern Cape, with heavy flooding anticipated in parts of the Western Cape.

This as a cold front is set to sweep over the Western and Eastern Cape from Friday, followed by a ridging high pressure system that will result in a deep layer of moisture, with low-freezing levels expected over the Eastern Cape.

The SA weather service forecasts showers can be expected in places on Friday, together with snowfall over the high terrain expected from mid-morning on Friday.

Emergency assistance as heavy flooding expected

Heavy rain leading to flash flooding is expected in places over the Cape Metropole and Cape Winelands from early Friday morning, subsiding by Friday evening.  

The City of Cape Town has advised those affected to call the 107 Public Emergency Contact Centre in the event of flooding or any other weather-related emergency by dialling 107 from a landline (this is a free call) or 021 480 7700 from a cellphone. The relevant network charges will apply for such calls.

By Friday afternoon, rain is expected over the Eastern Cape and by the evening rain is expected over the southern parts of KwaZulu-Natal.

Mountain Pass closures due to hazardous snowfall

Travellers are also being warned certain mountain passes may be closes, specifically the Outeniqua Mountains, Winterberg and the Southern Drakensberg towards the north-eastern corner of Eastern Cape.

Snow is expected to hit the Sneeuberg range near Nieu-Bethesda, but the snowfall is forecast to be short-lived with no closures required in the area. 

In addition to this, the SA weather service has advised small stock farmers to take the necessary precautions against the expected cold, wet and windy conditions. Farmers will especially need to take care on Saturday night in the north-eastern extremes of the province.

Gale force winds expected

High seas with wave heights in excess of 6m are expected between Cape Columbine and Plettenberg Bay on Friday, as gale force westerly to north-westerly wind at 65-70km/h can be expected on Friday afternoon between Slangkop and Cape Agulhas. 

By mid-morning on Saturday, gale force westerly winds are also expected along the coast and adjacent interior between Plettenberg Bay and Port Alfred, only moderating towards Saturday evening. 

While the SA weather service expects a further drop in maximum temperatures from Saturday, no rainfall has been forecast over the extreme Eastern parts of province, towards Mthatha.  

Temperatures already began plummeting on Thursday with -3°C recorded for Gauteng's Vereeniging and the Northern Cape's Sutherland, while the mercury dropped to 0°C in Mpumalanga's Standerton, the Northern Cape's Calvinia as well as the Free State's Bethlehem.

On Friday, maximum temperatures in Johannesburg will be 21°C, Pretoria will be 23°C and Bloemfontein in the Free State will be 19°C.
