SA Weather Service issues level 5 warning for disruptive rain on Wednesday



The South African Weather Service (SAWS) has issued an orange level 5 warning for disruptive rain leading to flooding of roads and settlements (formal and informal) as well as damage to property over
the David Kruiper Kai !Garib, Joe Morolong, Tsantsabane and !Kheis local municipalities of the Northern Cape province on Wednesday.

A yellow level 2 warning for disruptive rain and severe thunderstorms has also been issued over the Siyathemba, Siyancuma and Francis Baard local municipalities of the same province on Wednesday.

According to the weather service, the disruptive rain will lead to flooding of roads and settlements (formal and informal) as well as damage to property.

A cut-off low pressure system which developed along the coast of Namibia on Sunday moved over the Northern Cape on Tuesday, said the weather service.

Cut-off lows are associated with widespread instability in the atmosphere, which can promote periods of prolonged rainfall.

“Showers and thundershowers can be expected over parts of the Cape provinces from Monday onwards with associated cold daytime temperatures and windy conditions while spreading to parts of the Free State and North West on Tuesday night and Wednesday,” warned the weather service.

“Unseasonal (but not uncommon) 24-hour rainfall of 20 to 35 mm can be expected over parts of the
Northern Cape, Free State and North West. The onset of the rainfall is expected over the Northern Cape
on Monday, while spreading to the Free State and North West on Tuesday night. Strong gusty winds of 50
km/h can also be expected over these areas from Monday. Although cold daytime temperatures are
expected, snowfalls are likely to be confined to the Drakensberg regions and Lesotho on Wednesday,
spreading to the high-lying areas of the Western and Eastern Cape on Thursday.”
