It looks like it's going to be a cold and wet weekend for much of the country.

The South African Weather Service says another Spring cut-off low is expected to bring strong winds, heavy rain and very cold conditions across SA.

"The system is expected to pass over the western parts of the country on Saturday while propagating eastwards and eventually exiting the country by Tuesday. There will be near gale winds over the Cape provinces but fresh to strong wind over the North West, Gauteng, Free State and western parts of KwaZulu-Natal on Sunday, ceasing by Monday," the forecaster warned adding that this can result in damage to settlements, affect driving conditions along the N1 and N3 with possible problems for high-sided vehicles affected by winds, falling trees and possible blowing sand and dust.

Saws warned of scattered to widespread showers and thundershowers can be expected over the western parts of the country, while spreading over the central and eastern parts on Sunday and Monday but are expected to cease from the west by Tuesday.

Residents living in the south-west parts of SA can expect heavy downpours with rainfall accumulations exceeding 60mm n the south-west parts of the country on Sunday.

Saws said while it will advance along the south coast of the Western Cape and adjacent interior on Monday.

"This can be coupled with flooding of roads and settlements, damage or loss of infrastructure, property, vehicles, livelihoods and livestock, with the possibility hail. Along the coastal regions strong winds, coupled with very rough seas with wave heights of four to five metres, reaching higher heights by Saturday along the extreme south-western coastline by Monday. The waves are expected to subside on Tuesday," Saws said.

Meanwhile, temperatures are expected to be warm to hot, however a significant drop in temperatures can be expected from the west on Sunday, where temperatures will be cold to cool while these temperatures progress over the central by Monday.

Saws has issued these warnings for Sunday and Monday:
