Tornados which are caused by severe thunderstorms are not an unusual weather system in South Africa, according to forecaster at the SA Weather Services, Christina Thaele.
Two tornados swept through Magaliesburg and Tembisa this week, the second which ripped through parts of Tembisa on Tuesday afternoon and left a trail of destruction.
“The only thing unusual about this week’s tornado, is that this kind of system is normally experienced during spring and early summer seasons, and not during winter,” Thaele said.
Asked if South Africans should prepare themselves for similar weather conditions in the coming summer season, Thaele said it was still too early to say.
Meanwhile, sports fans planning to attend the rugby and soccer matches at Ellis Park and FNB stadiums can look forward to clear conditions throughout the weekend.
Contrary to the icy cold and wet weather conditions that gripped most parts of the country this week, Thaele said maximum temperatures are expected to gradually improve in Gauteng this weekend.
Johannesburg is set to peak at 20 degrees Celsius on Saturday before rising to 21 degrees Celsius on Sunday.
“Similar conditions can also be expected in other parts of the country, particularly those that were also affected by the cold and weather conditions. Residents in parts of KwaZulu-Natal and the Free State can still expect some light showers,” Thaele said.
But minimum temperatures are expected to remain in the cold category.
Despite the cold weather, Eskom said its power system has been able to cope with increased electricity consumption.
This week, President Jacob Zuma also launched Unit 4 of the Ingula Pumped Storage Scheme, marking a key milestone towards the full commercial operation of the entire pumped storage scheme ahead of the scheduled deadline of May 2017.
Upon completion, Ingula will be Africa’s newest and largest pumped storage scheme, and the 19th largest in the world.
Ingula’s Unit 4 came into commercial operation on June 10, six months ahead of schedule.
It has been consistently adding 333MW into the national grid to ensure security of supply.
It is the first of Ingula’s four units to come into commercial operation.
The remaining three units have been synchronised to the national grid and are on track for commercial operation within the first half of 2017.
Once completed, all four units of the Ingula Pumped Storage Scheme will produce a total of 1 332 MW pf electricity.
