Monday looks wet and unsettled across much of the country, with showers and thundershowers spreading over Gauteng, KwaZulu-Natal, the Free State, Mpumalanga, North West and the Northern Cape, where several minor severe thunderstorm warnings are in place, so keep an umbrella handy and take care on the roads. Cape Town stands apart with clear skies and a warm high of 31C, while Gqeberha starts off misty and Polokwane stays cloudy, and Durban holds mild and muggy between 18 and 25C. Do bear in mind that extreme veld fire conditions remain a concern, so it is wise to stay cautious around dry, open areas even as the rain moves in elsewhere.
