The South African Weather Service (SAWS) has warned that the Eastern Cape and KwaZulu-Natal will experience disruptive rain while severe thunderstorms are likely to occur in the Free State, North West as well as the Northern Cape.
“A cut-off low pressure system, surface trough and ridging high will result in scattered to widespread showers and thundershowers resulting in flooding in places,” said SAWS.
A surface high pressure south of the land will feed in a deep layer of moisture over the Eastern Cape, resulting in heavy downpours along the southeast coast between Cape St Francis and Port St Johns where the highest amounts of rainfall are expected between Monday evening and Tuesday afternoon.
The latest models are increasing rainfall along the south coast.
