DOWNPOURS are expected to hang around for much of the weekend in Burton and South Derbyshire following the hottest day of the year.
Temperatures reached 27C yesterday after an early-morning drenching gave way to blistering sunshine.
But people in the region are now being warned to be wary of the possibility of flash flooding as well as the intense heat.
Downpours and thunderstorms were expected to arrive in the region last night and while conditions are set to remain warm, the wet weather is likely to dominate.
The Met Office said that it would still be warm and humid in between the showers.
A spokesman said: "Some areas will miss the worst of the storms while nearby spots experience severe downpours, with some localised flooding. The public are advised to stay in touch with the latest forecasts and warnings through Saturday."
While the weather remains warm, advice has been issued to the elderly, young people and those with illnesses.
Staffordshire County Council's health chief Robbie Marshall said: "It's important to keep an eye on elderly relatives and neighbours."
