Although tropical cyclone Dineo has been downgraded to a tropical depression since making landfall, its effects were still felt across Mpumalanga and Limpopo where heavy rains and strong winds were experienced on Thursday. Dineo first hit Mozambique, where some areas reported more than 150mm of rain.

According to 24hr rainfall observations from 8am on Thursday to 8am on Friday, some areas in the lowveld received close to 100 mm of rainfall. Graskop in Mpumalanga  surpassed 100mm with a whopping 166mm.

The tropical depression is now situated over southeastern Botswana but is still affecting northeastern South Africa.

A warning for heavy rain leading to localised flooding is still valid in the Ehlanzeni District of Mpumalanga as well as Vhembe, Mopani and Capricorn Districts of Limpopo.

Flooding Awareness:

  • Do not try to cross flooded rivers or streams.
  • Do not drink floodwater since it may be polluted.
  • Stay away from collapsed power lines and cables after a flood as live electricity could still pass through them.
  • Turn off the electricity during a flood.
  • Store away clean drinking water and food.
  • Listen to weather reports and instructions of local disaster managers.
  • If necessary, evacuate the flooded area.

After a flood:

  • Avoid floodwaters; water may be contaminated by oil, gasoline, or raw sewage. Water may also be electrically charged from underground or downed power lines.
  • Avoid moving water. Remember fast flowing water only 16 cm deep can sweep you off your feet.
  • Be aware of areas where floodwaters have receded. Roads may have weakened and could collapse under the weight of a car.
  • Stay away from downed power lines, and report them to the power company.
  • Clean and disinfect everything that got wet. Mud left from floodwater can contain sewage and chemicals.

Windy conditions are also expected for the province and will spread westwards into the North West province today. Wind speeds exceeding 40 km/h in Limpopo, parts of the Highveld and the eastern parts of North-West with wind gusts of more than 60km/h are possible this Friday.

The system will weaken further as it moves into western Botswana over the weekend. However, it will get caught up in a trough that will form over western South Africa on Sunday.

The trough is also a low pressure, but it extends over a broad area. It will transport moisture from the tropics into western and central South Africa from Sunday through to mid next week.

Weather forecasting models are indicating significant rainfall over parts of North West, Free State, Eastern Cape and KwaZulu Natal, from Sunday into next week.
