After months of warm, sunny weather, the Met Office has issued a yellow weather warning in London.

The city is set to see heavy rain which could cause travel disruption today.

The heavy rain warning is in place from Thursday, October 12 at 9pm until midnight on Friday, October 13.

It is set to affect all parts of London much of the south, with both the west and east affected as well as far as Wales.

The weather warning across London will likely see some spray and flooding on roads probably making journey times longer.

The Met Office also warning that flooding to some homes and businesses is likely.

Plus bus and train services are probably affected with journey times taking longer.

Discussing the weather warning for rain, a Met Office spokesperson said: "Rain, heavy and persistent at times, is expected to develop through Thursday evening, before affecting much of England and Wales through Friday.

"Rain gradually clears from the north through Friday afternoon and evening.

"Widely 10-20 mm of rain is likely but in the wettest spots 30-50 mm is possible, and some high ground of Wales especially could see 60 to 70 mm.

"Across the south of the area its possible some thunderstorms may break out, and these could bring 20-30 mm of rainfall in a couple of hours."
