Cape Town – Despite having decreased in intensity, the South African Weather Service says highspeed winds in excess of 50/km and heavy rainfall can still be expected as the storm makes its way across the north, "posing a great risk" right into the weekend.

The South Africa government has called on communities to be on the high alert and take precautions especially ensuring children are safe and not crossing bridges or near possible rivers that are at risk of flash flooding.

Warnings of heavy showers and thunderstorms over the lowveld and escarpment regions of Mpumalanga and Limpopo remain for Thursday evening into Friday with an estimated 100 to 200mm rainfall expected over the eastern half of Limpopo province. These conditions will continue into Friday, 17 February, says the weather service. 

In the latter half of Friday, patches of heavy rain may also occur over the western parts of Limpopo as well as northern Botswana, as the remnants of the low track moves progressively further westwards over the African subcontinent. 

By Saturday, patches of heavy rain could even persist over the northern parts of Namibia and Botswana respectively.

Flood Risks

The risk of flooding will be particularly severe along the banks of the lower Limpopo river and Olifants river systems, as they flow through southern Mozambique, towards the floodplain region adjoining Xai-Xai in the south of Mozambique, the SA Weather Service warns.
