A cut-off low (COL) pressure system is situated over the central interior of the country on Sunday, resulting in scattered to widespread showers and thundershowers over most parts of Gauteng, Mpumalanga, and Limpopo, but isolated over the eastern parts of Limpopo.

Some of these thunderstorms have the possibility to become severe and cause flooding, large amounts of small hail and excessive lightning, as well as strong damaging winds.

Scattered to widespread showers and thundershowers are possible over the central and eastern parts of the country by the afternoon, and snowfall possible in some of the mountains bordering Lesotho.

Rainfall of between 20mm and 40mm in possible in places, possibly resulting in significant impacts as the ground is already saturated. Major travel disruptions are possible.

From Monday it should be partly cloudy and cool to warm conditions over the central and eastern parts of the country, with isolated to scattered showers and thundershowers possible by the afternoon. It will be cold in places in the eastern half of the Eastern Cape, according to the SA Weather Service.
