Sunday looks like a real mixed bag across the country, with a wet, unsettled feel over the eastern and central regions where Durban, Bloemfontein, Polokwane and Mbombela can expect showers and thundershowers, and four separate minor Disruptive Rain warnings are in place to keep an eye on. Out west it’s a warmer, calmer story, with Cape Town basking in clear skies and a high of 30C, though two Extreme Veld Fire Conditions warnings are a stark reminder to stay cautious in the drier parts. Johannesburg, Gqeberha, Mahikeng and Kimberley should see partly cloudy skies in the low-to-mid 20s, while any warnings still active from today are worth watching as the afternoon winds down.
