A yellow weather warning has been put in place as England and Wales brace for flooding, heavy rain and thunder.
The thunderstorm warning, covering much of England and parts of Wales, is in place from 4am on Sunday until 5am on Monday.
Forecasters are warning that the wet weather could lead to flooding, leaving businesses and homes at risk of damage.

A warning on the Met Office’s website says: “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.”
It added that there could be disruptions to travel including road closures and train cancellations.
Met Office Meteorologist Rebecca Hudson said that the risk is mostly confined to Central and southern England.

She said the weather warning is almost in a “triangular shape”, from East Yorkshire roughly down to the Cardiff area, East Devon, to London as well, and East Anglia.
Ms Hudson said there will be some “heavier showers” over Sunday night, before drying out on Monday – with some sunny spells even on the cards.
“The heavier band moves through tomorrow morning and then weakens out into the afternoon but then there are some further heavy showers tomorrow night,” she said.
“And then as we go in overnight, things will gradually dry out into Monday morning.

“There will be some heavier showers overnight on Sunday into Monday, but these will gradually weaken and then Monday will be a lot drier with some sunny spells around as well,” she added.
Sharing advice from the RAC and National Highways, the Met Office is advising drivers to slow down in thunderstorms and find alternative routes if roads are flooded.
