Britain is braced for torrential downpours and storms later this week as the Met Office issued weather warnings on Tuesday (August 11).
A yellow weather warning for rain was issued for England and Wales as wet and stormy weather is forecast to sweep across Britain later this week.
The unpredictable weather is due to hit London and the South East on Thursday morning (August 13) with the warning in place from 6am until Friday (August 14).
The Met Office said: "A developing area of rain is expected to reach the south of England early on Thursday morning, before pushing north across much of southern UK during the day. The rainfall is likely to be heavy and thundery at times, with the potential for torrential downpours in places.
"The public should be aware of a significant risk of very localised disruption to travel due to surface water flooding. Lightning may be an additional hazard."
The Met Office's chief forecaster added: "An area of low pressure is expected to develop just to the north-west of Spain in the next 12-24 hours. This system is then expected to push north across Biscay and into the south of the UK early on Thursday.
"With very warm air entrained into the system, locally heavy and thundery rain is likely to develop as the system pushes across parts of England and Wales.
"Around 15mm-30mm of rain is possible in six-12 hours, with as much as 50mm possible very locally by the end of Thursday.
"The development of this system is very complex, and uncertainty in the details of this event is relatively high."
