Pictures show torrential rain across areas including south west London, causing a number of London train and tube stations to close.
Underground stations including Wimbledon in the south and Chalk Farm and Hampstead stations in north London, have drawn their barriers due to the heavy rainfall.
Euston Station lines had to be shut down after the intense downpours on Monday evening, with people unable to travel in or out of the city via the major transport hub.
Cars were also filmed struggling to make their way through streets that appear to have turned into rivers after several inches of rainwater.
Raynes Park
The flooding problems appear to be concentrated in south west and north west London, including boroughs such as Richmond, Kingston, Merton and Sutton.
Residents in a number of areas such as South Hampstead, West Hampstead, Raynes Park, Friern Barnet, Isleworth and Wimbledon have taken to social media to post videos of the scenes and expressing shock at finding whole roads in their neighbourhoods submerged underwater.
Pictures have also emerged of people swimming in ponds created by the thunderstorms on Primrose Hill.
Sutton
In South End Green, firefighters were called to help carry some walkers to safety across roads that had been flooded by water pouring off Hampstead Heath.
Tenants of Lancaster West Estate in North Kensington, near Grenfell Tower, complained that a storm had caused a nearby manhole cover to blow off and “water and raw sewage” was flowing around the block.
London Fire Brigade said it had taken more than 1,000 calls related to flooding.

A spokesperson for the service said: “We’re asking people not to walk through or drive through the flood water. Flood water can be contaminated and vehicles can become unstable.
“We’re also asking people to look out for their neighbours and look out for weather warnings in their area.”
Elsewhere in the UK, Preston has also been affected by flooding with a section of the M6 having to be closed to traffic for some time on Monday afternoon. It has since reopened.
