Cold weather and rain expected for South Africa

South Africans can expect a cold snap to affect most the country from Wednesday onwards, according to the SA Weather Service.

Particularly cold daytime temperatures are expected to dominate the south-western parts on Wednesday, 16 August 2017, spreading to include the central and eastern parts on Thursday.

Significant snowfall can also be expected over the southern and central Drakensberg.

Snowfall could be heavy over the north-eastern parts of the Eastern Cape, possibly leading to the closure of the majority of mountain passes in the region as well as associated disruption of traffic flow.

Rain and showers are expected over the south-western parts of the country on Tuesday and Wednesday.

By Thursday, rainfall is expected to move eastwards, with the Eastern Cape and KwaZulu-Natal particularly well favoured to receive widespread rainfall.

These provinces may even experience heavy rainfall as well as localised flooding, especially along the coast and adjacent interior regions.

Along much of the southern coastline, periods of strong, gusty winds combined with moderate seas are expected.

These extreme weather conditions are due to the development of an intense trough (an extension of a low pressure) in the upper portions of the atmosphere, which is expected to move over the country on Wednesday.

Thereafter, the trough is likely to intensify further, becoming a so-called cut-off low pressure system on Thursday, 17 August 2017.

By Friday, this weather system is expected to exit the country, when rainfall will be restricted to the eastern extremities of the country, heralding a return to dry, settled weather this weekend.
