#Heatwave: Record-breaking temperatures to grip SA
The extreme heat conditions today will affect Gauteng, Limpopo, the Lowveld, and the Free State.
JOHANNESBURG - The South African Weather Service has warned South Africans to stay indoors and out of the sun as record-breaking temperatures grip the interior.
The mercury is expected to soar over the 40 degree mark in some parts today with respite only expected from tomorrow.
The weather service said the extreme heat conditions today will affect Gauteng, Limpopo, the Lowveld, and the Free State.
Forecaster Jan Vermeulen said people must take precaution against the heat.
"We'd like to see people stay in well ventilated rooms, take enough liquids and also wear cool light clothes and don't participate in strenuous activities."
While the heatwave intensifies, dam levels have dropped significantly as the country experiences its most severe drought since 1992.
Spokesperson for the Department of Water Affairs Sputnik Ratau said the extreme heat is exacerbating the drop in dam levels.
"The heatwave has obviously meant that we've had more evaporation in our water resources, especially our dams and open reservoirs. So it implies that we've had less water that we've had to be able to put into the system."
ER24's Chitra Bodasing said symptoms of heat exhaustion must be monitored closely.
"Severe heat exhaustion could lead to heat stroke and that in turn could result in a person losing consciousness, experiencing seizure and cardiac arrest."
She said if these symptoms persist medical assistance should be sought as soon as possible.
In the Western Cape, ER24 treated several people over the last few weeks who have been affected by the blistering conditions.
A woman was recently airlifted off Table Mountain after suffering from heat stroke.
