With Cape Town's dam levels dropping to 53.7%, the city is urging residents to adopt water-saving measures ahead of an unpredictable winter.

Cape Town could see a passing afternoon shower on Thursday, while Johannesburg and Pretoria face cloudy skies with possible thunderstorms and rain during the day and into the night.

Cape Town officials have thanked residents for the recent drop in demand, however, the window to avoid water restrictions is narrowing.

Expect morning drizzle in Cape Town on Thursday. Gauteng will be very warm and sunny with a slight, late storm risk overnight.

With dam levels significantly lower than last year, Cape Town has just 90 days to manage water consumption and avert potential restrictions.
