JOHANNESBURG - A severe storm has caused major damage to Johannesburg's power grid, leaving a number of areas without electricity.

City Power says several of its substations have been affected by lightning, with roads flooded and traffic light problems.

It says the prospect substation, which affects central and south Johannesburg, has been damaged along with the Fordsburg substation.

City Power's Yumna Sheik says technicians are trying to restore power.

"We will not have time in terms of the restoration and [people must be] advised that it is because of the storm."

There are also delays in flights at OR Tambo International Airport due to the rain and lightning in Gauteng.

Details of what flights have been affected have not yet been confirmed.

Airports Company South Africa's Deidre Davids has advised commuters to check in with their airlines before arriving at Cape Town International.

"There are currently five arriving flights delayed as a result of adverse weather conditions in Johannesburg and two outgoing flights, which are currently delayed. We do expect the poor weather to have a knock-on effect on later flights today. So if you're travelling, be sure to make contact with your airline to get up-to-date flight information."

Commuters are advised to check flight times before leaving for the airport.

Meanwhile, Johannesburg Water has confirmed a water pipe has burst in Northcliff Koppie which is affecting major parts of the city this afternoon.

The same pipe burst in Randburg last week but was repaired.

Areas affected include Cresta, Robin Acres, Robindale, Ferndale, Blairgowrie and Linden.

Johannesburg Water's Hilgard Matthews said, "A pipe has burst and we just want to warn the people within those areas that the tower would be out of water within the next two hours."
