Kent's mini heatwave could be brought to an end by thunderstorms.
The Met Office has issued a yellow weather warning for the county which is in place from noon on Friday until 6am Saturday.
Across Kent people have been basking in temperatures in the high 20s and the forecast predicts they'll rise above 30 today and tomorrow.
It prompted health authorities to issue a heat health warning to vulnerable residents.
But now the nation's weather service is predicting thunderstorms are set to hit parts of the county including Kent, bringing the sunshine to an abrupt end.
It said there is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds.
There could be a direct impact on roads and public transport with delays likely to train and bus services.
There is also a small chance some communities may be cut off by flooded roads and power cuts could occur.
The Met Office forecast said: "Heavy showers and thunderstorms are likely to break out on Friday afternoon and evening.
"Many places will miss the storms, but where they do occur, torrential downpours could bring 30-50mm rain in an hour, with hail and lightning."
