Thunderstorms and heavy rain could cause flooding, travel disruption and power cuts later today, forecasters have said.
The Met Office has issued a yellow weather warning from 4pm to midnight across much of South Wales, southwest England and southern England.
Some areas could be hit by up to 40mm of rain falling within two to three hours, the weather agency said.
It added there was a “good chance” that driving conditions would be affected by spray, standing water or hail, while train services may also be disrupted.
Flooding to homes and businesses is also possible, along with “some short-term loss of power,” the Met Office added.
Forecasters believe thunderstorms are most likely to occur in south-facing coastal areas, with hail and strong winds accompanying the heaviest rainfall.
Further heavy showers and thunderstorms are expected across central and southern areas of the UK on Tuesday and into Wednesday.
The weather service said it also had “increasing confidence” that ex-Hurricane Kirk will track to the south of the UK, bringing heavy rains and strong winds to northern France.
Yellow weather warnings are issued by the Met Office for “low level” impacts which have the potential to cause disruption in some areas.
