Thunderstorm warnings have been issued for much of the UK as heavy rain means there is a risk of possible flooding.
A yellow weather warning covering much of England and parts of Wales is in effect until 5am Monday.
Forecasters warn the wet weather could lead to flooding, damaging businesses and homes.

A warning on the Met Office’s website said: “There is a small chance that homes and businesses will be flooded quickly and some buildings will be damaged by flooding, lightning, hail or high winds.”
It added there could be travel disruptions, including road closures and train cancellations.
Met Office meteorologist Rebecca Hudson said the risk was mainly confined to central and southern England.
She said the weather warning is almost “triangular” in shape, from East Yorkshire roughly down to the Cardiff area, East Devon, also to London and East Anglia.
Ms Hudson said there will be some “heavier showers” on Sunday evening before drying up on Monday – with some sunny spells even on the maps.
“There will be some heavier showers overnight from Sunday to Monday but these will gradually weaken and then Monday will be much drier with some sunny spells,” she added.
The Met Office shares advice from the RAC and National Highways, advising drivers to slow down during thunderstorms and find alternative routes when roads are flooded.
