A yellow warning has been issued for rain across Bucks.
The Met Office said the warning will be in place from 5pm tomorrow (Thursday) until 10am on Friday.
Forecasters said: “There is some uncertainty in the details, but some locations may see up 20-30 mm of rain in two to three hours and perhaps 40-60 millimetres in four to six hours."
“Given the recent very wet weather, this will bring the potential for further flooding and transport disruption.”
