Isolated thunderstorms with very heavy rain, hail and gusty winds are possible later this afternoon and early evening.
The public should be aware of the risk of very localised surface water flooding, particularly if the thunderstorms affect urban areas.
Increasingly hot and humid conditions are likely across many central and southeastern parts of England during today, with the high temperatures likely to trigger a few intense thunderstorms during the late afternoon and evening. These could produce 30 mm of rain in less than an hour, large hail and also squally winds.
