Johannesburg - Limpopo, Mpumalanga and South Africa’s north-eastern regions should brace for further rainfall and high wind on Tuesday as Cyclone Eloise veers west, the South African Weather Service (Saws) said on Monday.
Eloise made landfall in southern Mozambique at about 2.30am on Saturday. It brought heavy rains and strong winds as it headed along the escarpment to the lowveld areas of Limpopo, Mpumalanga and the northern parts of KwaZulu-Natal.
Saws said rainfall of between 50mm and 128mm was reported in these areas from 12am on Saturday, with many trees being uprooted, and there was damage to temporary structures and roofs were blown off houses.
Strong surface winds circulating around the centre of Eloise resulted in south-easterly to easterly gale-force winds of around 80km/h on Monday, especially over northern Limpopo.
The forecaster expected Cyclone Eloise to reach the south-western borders of Botswana by Wednesday, and to connect with a system from the Atlantic on Wednesday which would likely result in rainfall in the North West and north-eastern Cape.
Eloise has put South Africa’s transport and other utilities on alert for possible disruptions.
Transnet’s port infrastructure and marine services operating division, the Transnet National Port Authority, put measures in place on Friday to ensure that minimal disruption was experienced by port users should Eloise hit Durban.
The Port of Durban’s general manager, Moshe Motlohi, said terminal operators had been directed to have business continuity plans on standby for adverse weather conditions.
Transnet’s National Ports Authority has an agreement with the South African Weather Service on an early warning system to help manage risks of adverse weather conditions, he said.
Peter Besnard, South African Association of Ship Operators and Agents chief executive, said that the harbour master had sent out a warning to all lines and vessel agents warning them of the circumstances that could prevail.
“Before the storm reached our shores we were plagued by wind in literally all coastal ports for a number of days, impacting heavily on ships berthing and port operations, and that coupled with labour issues from the Covid-19 pandemic and now the storm will surely add to the current woes being experienced,” said Besnard.
Eskom also put contingency plans in place on Friday, as most of its power stations are in Mpumalanga.
Eskom spokesperson Sikonathi Mantshantsha said they had experienced no negative impact from the storm by mid-afternoon on Monday and there had also been no impact on the Cahora Bassa transmission line infrastructure between South Africa and Mozambique, lines that were reinforced a few years ago after similar storms.
Typically, heavy rainfall for four or fewer days does not pose a significant threat to power station operations, but continuous heavy rainfall for more than four days can hamper coal handling at the power stations and at the mines supplying them.
Some power stations in Mpumalanga have been experiencing ash dam constraints, and continuous heavy rainfall over these power stations could hamper operations and recovery efforts already under way.
Extra staff were in place to attend to faults as they occurred.
Kruger National Park, made up of around two million hectares of wild land that runs through Mpumalanga and Limpopo, was in the high-impact zone as Eloise devastated parts of neighbouring Mozambique just days before.
SANParks communications manager Ike Phaahla said some parts of the park were still under water and could only be accessed once the storm subsided.
Before the arrival of Eloise, the park relocated tourists from areas which were expected to suffer the worst of the storm.
