Cape Town - A heatwave with persistently high temperature is expected in places over SA's western interior while heavy rain and flooding continue over SA's east on Wednesday, 06 December.


A heatwave with persistent high temperature is expected in places over the western interior of the Northern Cape, West Coast District, Cape Metropole and Cape Winelands until Friday, 08 December.

Fire dangers

Extremely hot fire dangers are expected in places over the western interior of the Northern Cape, West Coast District and Cape Winelands in the Western Cape on Wednesday, persisting into Thursday and Friday.

Heavy rain and flooding alert

Heavy rain leading to localised and flash flooding is expected over the Highveld of Mpumalanga, south-western Limpopo, Gauteng, the eastern part of both of Free State and North West and over the western KwaZulu-Natal.

On Wednesday, a 30% - 80% chance of rain has been forecast in central parts of the Northern Cape and Eastern Cape, over SA's eastern parts, with rain across all provinces with the exception of the Western Cape.

The South African Weather Services also issued a watch for localised and flash flooding that can be expected over Mpumalanga, the south- eastern parts of Limpopo, the eastern and northern parts of KwaZulu-Natal and the extreme northern-eastern parts of Gauteng.

The SA Weather Services urges everyone that road flooding is a serious risk, drive safely.

Here's what can be experienced in affected areas:

Flooding of roads and settlements.
Occasional poor road visibility.
Fast flowing streams pose danger to life.
Displacement of affected communities.
Damage to property, infrastructure and loss of livelihood.

Precautions to take during flooding

If walking outdoors, SA Weather Service advises that you avoid crossing rivers and swollen streams where water is above your ankles.

"Just 15cm of fast-moving flood water can knock a person off their feet and a depth of 60cm feet is enough to float a car. Never drive on a road covered by water. You do not know how deep it is or if the road has been washed away," warns SAWS.

"If trapped within a vehicle by rising waters, abandon it immediately and seek higher ground," says SAWS, adding that people must listen to warnings and be even more cautious at night when it is harder to see flood dangers.
