Flash-flood hit Londoners were waking up in emergency accommodation this morning after their homes were deluged with water and left without power.
Some families in West London had to shelter in a makeshift community centre after they were washed out of their multi-million-pound properties.
Others were facing rush-hour chaos today as many Tube and rail services are still suspended after 'biblical' storms saw flash floods hit the capital last night and left a trail of destruction across the city.
Network Rail has confirmed widespread disruption continues across the Thameslink network despite services resuming within the last hour while Tube services on the Circle, District and Hammersmith & City lines remain partially suspended due to the flooding.
The London Overground also remains partly suspended with severe delays across the network while teams work to repair the damage caused.
Last night, flood waters poured through the streets of Portobello Road in Notting Hill after nearly three inches of rain hit the capital in just 90 minutes and in Raynes Park, south London, cars were left abandoned in around 2ft of water after torrential downpours caused travel chaos and left homes and businesses flooded.
Meanwhile in Turnpike Lane, north London, people were spotted wading through the water in the streets as the heavy rain pelted down and flooded the roads.
In other scenes, Sloane Square tube station in Chelsea was forced to shut down after fast flowing water poured down the steps of the underground and in South Hampstead motorists desperately tried to navigate their way through the roads as the heavy rainfall continued to fall.
Elsewhere, in St John's Wood, one homeowner was left shocked as water began to splurge out of their overflowing toilet through their property.
MPS Westminster also reported heavy flooding around Colville Terrace, Holland Road and Ladbroke Grove and said the emergency services were now evacuating areas due to flooded properties and collapsed ceilings.
A spokesman said: 'Reports of heavy flooding around Westminster including Colville Terrace, Holland Road and Ladbroke Grove Emergency services assisting in evacuating areas due to reports of flooded properties and collapsed ceilings. Road closures are in place.
It came as the Met Office issued a yellow weather warning for rain for a large section of southern England and the Environment Agency issued one flood alert for areas close to the upper River Loddon in Basingstoke, Hampshire.
As the intense downpours ensued, the London Fire Brigade confirmed they had received more than 1,000 calls related to flooding and urged people to 'only call if there was a genuine emergency'.
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.'
Yesterday, Euston Station lines had to be shut down and underground stations, including Chalk Farm and Hampstead stations in north London and Wimbledon in the south, also drew their barriers due to the heavy rainfall.
A Network Rail spokesperson said: 'The line between Watford Junction and Euston has been closed and engineers are on site inspecting the track as the water recedes. As soon as it is safe to do so, we will have trains on the move again.
'We would advise anyone travelling this evening to check with their train operator or the National Rail Enquiries website for the latest information.'
