The Met Office has issued a weather warning as London braces for heavy thunderstorms this afternoon.

After an amber warning for rain was issued at the beginning of the week, which caused travel chaos as train lines flooded.

A spokesman from the Met Office said: "Whilst some places will escape them, thunderstorms will break out this afternoon and evening giving torrential downpours in a few places.

"20 mm rain may fall in an hour and, in some places, 30 to 40 mm rain may fall in two or three hours, thunderstorms will then slowly ease through the evening."

There is a possibility of delays to public transport and last minute cancellations due to the amount of rain predicted.

Spray and sudden flooding could lead to difficult driving conditions and some road closures.

You are advised to take extra care when travelling today and not to go out unless it's really necessary.
