A risk of flooding on Tuesday, according to the SA Weather Service, with models are showing areas of slow moving thunderstorms that may lead to places receiving 40-50mm of accumulated rain from the afternoon into the evening.

Significant impacts are possible due to it being the first significant rainfall for the season, therefore run-off is expected to be high and blocked drainage systems is possible.

Isolated showers and thundershowers are expected over the central interior on Wednesday.

Warnings from the SA Weather Service (SAWS):

A. yellow level 4 warning for severe thunderstorms on Tuesday with heavy downpours leading to localised flooding of susceptible roads and localised damage to infrastructure is expected over Gauteng, the eastern parts of the North West, north-eastern Free State and the extreme south-western parts of Limpopo.

B. yellow level 2 warning for wind and waves on Tuesday and Wednesday, leading to difficulty in navigation at sea as well as small vessels and personal watercrafts at risk of taking on water and capsizing in locality is expected between Hout Bay and Plettenberg Bay.

Extremely high fire danger conditions are expected over parts of the central Northern Cape as well as the extreme northern parts of Limpopo.
