Though no crippling snow storms - which led to the closure of large sections of highways and mountain passes across the country this weekend - are expected for the rest of the week, the biting cold will remain.

"What has happened is by no means over," warned weather forecaster Dipuo Tawana.

Tawana said people should brace themselves for "extreme, bone-chilling cold" at the weekend.

Another cold front is due to hit Western Cape on Friday.

Tawana, whose warning was echoed by KwaZulu-Natal forecaster Bubele Bulo, said light rain would continue to fall as the weather system moved up the east coast.

"We have issued a warning about very cold conditions, especially over the Eastern Cape's high-lying areas.

"Temperatures will continue to drop when the next cold front hits," Tawana said.

Eastern Cape weather forecaster Pumla Goba said: "Inland day temperatures will range between 10C and 16C [tomorrow], increasing to between 13C and 21C [on Wednesday]. The next cold front is expected to hit Eastern Cape on Saturday."
