Africa-Press – South-Africa. South Africans have been warned to brace for yet another storm system over the long weekend, only a week after high seas and strong winds battered the coastline.
According to the South African Weather Service (SAWS), a cut-off low-pressure system is expected to develop along the west coast of South Africa on Saturday night.
“Cut-off lows are notorious for causing widespread severe weather, such as flooding, heavy rainfall, and severe thunderstorms,” the SAWS said.
Widespread showers and thundershowers can be expected across western, central, and southern South Africa, particularly from Sunday.
“Light rain can be expected along the Garden Route of the Western Cape as well as the coast and adjacent interior of the Eastern Cape on Saturday.
“Isolated to scattered thundershowers will develop from the afternoon over the interior, extending from the eastern parts of the Northern Cape to the western Free State and later, the interior of the Eastern Cape.”

The weather will rapidly intensify by Sunday, resulting in widespread thundershowers and rain over parts of the Western Cape, Northern Cape, Eastern Cape, and southern Free State.
The Western Cape, Northern Cape, and western areas of the Eastern Cape may experience severe thunderstorms where bursts of intense rainfall may cause flash flooding.
Strong to gale-force winds and very rough seas of four to six metres are expected along the coastal areas, particularly along the Western Cape and Eastern Cape coast on Sunday and Monday.
The cold front will bring icy temperatures to the western and southern parts of the country from Sunday, and light snowfall is possible over the north-eastern high-lying areas of the Eastern Cape and Lesotho on Monday.
On Monday, the cut-off low will move to the southern coast, bringing widespread and heavy rainfall over the southern parts of the Western and Eastern Cape. These areas could experience between 60-100mm of rain in 24 hours and gale-force winds.
The cold front is expected to move away from the country on Tuesday.
The SAWS currently has a weather advisory in place for cold and wet weather over the Western and Northern Cape from Sunday to Monday.
Last weekend, around half of South Africa’s coastline experienced waves of up to 9.5 metres during a storm surge, exacerbated by spring tide and a cold front.
