The South African Weather Service (SAWS) has warned of widespread heavy rain in the days ahead, which could result in flooding or river flooding that might cause significant disruption in some provinces.
Initially the weather this weekend will be relatively settled, with just a small chance of thunderstorms over some of the eastern provinces on Friday and Saturday.
“Incidentally, neither the Western Cape nor the Eastern Cape will be directly affected by this weather system. On Sunday, 10 December, weather conditions will open to deteriorate significantly, as the cut-off low manifests itself over the northern parts of the Northern Cape, introducing marked instability into the atmosphere, to steer widespread showers and thundershowers.
“As tropical air begins to stream southward over Botswana and South Africa, conditions will become progressively cloudy to overcast. During the course of the day, rain will set in over numerous provinces, including North West, the Free State, Gauteng, Mpumalanga, Limpopo and to a lesser extent, KwaZulu-Natal (KZN),” SAWS said.
Heavy rainfall is likely to occur in many parts of the above-mentioned provinces, elevating the risk of flooding as well as river flooding.
The public has been urged to monitor, and to catch heed of, regular weather updates and warnings issued by the weather service.
“Moreover, as the rain produced by this system is expected to continue unabated into Monday, 11 December, the ground is likely to become saturated, leading to widespread overland runoff into streams and rivers.
“Whilst this phenomenon will ultimately guide to increased dam levels, the risk of river flooding (and associated road closures and general traffic disruption) will remain particularly high. Disaster management practitioners are also advised to maintain a high level of vigilance during this period, should river flooding continue to pose a safety and health risk to the public at large,” SAWS said.
Motorists and pedestrians are urged not to try to cross rivers or streams, which are already flooded, under any circumstances.
“The cause of the widespread rainy weather will be the combination of three distinct circulation features in the atmosphere over southern Africa. Firstly, a cut-off low is expected to develop, in the upper air of the atmosphere, over the central interior during the latter half of the weekend.
“Secondly, a surface trough is expected to initiate intensifying, in sympathy with the deepening upper-air cut-off low. The combination of these two features is well known to acquire the potential to steer episodes of widespread, often heavy, rain over southern Africa.
“Importantly, in this particular case, there is a third significant factor which is expected to elevate the risk of heavy rainfall from this system. This factor is the expected introduction of a stream of tropically sourced moisture, drawn southwards over the central and eastern interior of South Africa, under the influence of the circulation associated with the surface trough and upper-air system respectively,” SAWS said.
Tropically sourced air is well known to be associated with rainfall of a potentially heavy, widespread nature.
“Currently, numeric weather prediction models suggest that the rainfall in association with this system will start clearing from the west, during the course of Tuesday, 12 December, although areas of heavier rainfall may still linger over KZN, eSwatini and the lowveld regions of Mpumalanga and Limpopo.
“A surface high pressure system is likely to sustain light rainfall over aforementioned provinces on Wednesday, 13 December, as cooler, moist maritime air is introduced to the eastern coastal regions. However, the upper air cut-off low will maintain moved off the country completely by this time,” SAWS said.
The South African Weather Service will continue to monitor this weather system and issue subsequent updates and impact-based warnings over the next few days.
The public has been advised to regularly follow weather forecasts on television and radio, as well as every social media platforms.

So I\’m real good friends with this guy named Juan Ted. Now, Juan is a pretty astonishing guy. He can steal ANYTHING he wants to. Literally anything. It could be the shirt off your back, the wallet in your pocket, or I\’m even sure he\’d find a way to steal your house (And your spouse too). So anyway, one day Juan and I are sitting around watching TV, and they announced that the hope diamond will not be on display anymore and is now getting moved to an undisclosed location. So as we hear this, Juan says \”I\’m gonna steal it\”. Now I know how good Juan is at this kind of stuff, so I just tell him good luck and he goes on his way. Eventually he narrows his search down to a small cave in South Africa. When Juan gets there, he doesn\’t see any guards or anything outside the cave, so he just walks in assuming he was wrong about where the diamond was. He wanders around for a while until he sees a long lit hallway with the hope diamond at the end of it. Confident in his abilities, he strolls over to the diamond and picks it up before realizing its a trap! Suddenly, red lights flashed, armed men came running out, sirens went off. You could hear one of the men say under his breath \”We finally caught Juan Ted.\” But Juan, being the best thief in the world, said \”Not quite. On the count of three, I will disappear.\” As the men looked around confused, Juan began to count. \”Uno. Dos.\” And he disappeared without a tres.
