Heavy showers and thunderstorms are forecast for Oxfordshire today as the Met Office issued a severe weather warning.
The warning is for between 12.10pm and 9pm today and could see more than 30mm of rain in a two to three hour period as well as lightning.
A Met Office spokesman said: "The public should be aware of the risk of localised surface water flooding, with the added hazard of lightning in some areas.
"An unstable and moist flow across southern parts of Britain will provide the basis for some intense showers through today, and with the winds lighter than recent days, these will last longer where they do occur, perhaps producing in excess of 30 mm of rain in 2 or 3 hours in a few localities.
"But as so often happens on showery days, some places will escape the worst."
